With the 6mm Dasher cartridge becoming popular with PRS/NRL competitors as well as the benchrest crowd, we thought it was time to re-visit a special rifle chambered for the 6mm Dasher wildcat. This gun has a great story behind it. Forum member Bob A. (aka “Killshot”) used his “Forum Classifieds Special” to beat all comers in the F-Class Division in the American-Canadian Match and the Long Range Regional Match in 2013 in Sacramento, CA.
Bob’s 6mm Dasher sports a blue-printed Rem 700 action. Who says you need a high-dollar custom action to run with the big dogs? In fact, this same gun, built with components sourced from AccurateShooter Forum Classified Ads, set a Sacramento F-Class range record of 200-17X a few years back. In this story, Bob talks about the build, and he explains his methods for loading ultra-accurate Dasher ammo.
Bob’s Budget-Build Dasher F-Classer
I wanted to build a proper rifle for F-Open but needed to keep it simple and, well, cheap. I found a solid “base” to build on in the form of a Dave Bruno-built, “pre-owned” 6-6.5×47 Lapua that I located in the AccurateShooter Forum classifieds in late 2011. The base action was a trued and blue-printed Remington 700 receiver circa 1971 with a spiral-fluted bolt. It was in a Shehane ST1000 stock painted sky blue and had a Jewell 1.5-oz BR trigger. I sent the bolt to Greg Tannel (Gretanrifles.com) to have the firing pin hole bushed and sleeved, the ejector removed and the hole filled and the face trued. I upgraded to Tannel’s Light Steel firing pin assembly while it was out.
Having the working bits completed, I needed a barrel. So I went to the AccurateShooter classifieds again and found a 1:8″-twist, 30″ x 1.25″ (diam.) Bartlein with a 0.236″-land bore. I called Dave Kiff and explained my pursuit and he recommended his PT&G “world record” 6 Dasher reamer (.2704″ no-turn neck and .104″ freebore). A month or so later the reamer and gauges arrived.
I had the barrel chambered by Marc Soulie of Spartan Precision Rifles (510-755-5293, Concord, CA). Marc is a great builder and I’m pleased to call him a friend.
The rifle got its good looks from a Pennsylvania artist named Kenny Prahl. His Prahl Designs shop (724-478-2538) added the white ghost-flames over the existing sky blue metallic paint.
Looks Great, Shoots Better
Fire-forming showed great promise — ten-shot groups of half an inch at 200 yards were typical. I lost only one case to a split neck and the “blow lengths” are good and consistent. This was followed up with load development which saw 100-yard, five-shot groups in the .1s and .2s as the rifle showed its preference for Reloder 15 over Varget powder, and for CCI 450s over all other primers. The bullet of choice was the ever-popular Berger 105gr Hybrid Target.
In February 2012 I began shooting the Dasher in monthly club matches at the Sacramento Valley Shooting Center, the home range of a number of excellent F-Class, Benchrest and High Power shooters. Using a Farley Coaxial rest up front (also picked up from a WTB ad on AccurateShooter’s Forum) and an Edgewood bag in the back, I gradually improved my gun-handling to the point where I could shoot a respectable score. This was very different from the bipod shooting I’d done in the past in F/TR.
Dasher Loading Tips
My chamber is set up for blue box Lapua 6mmBR brass. My case preparation is straight-forward. I fire-form with virgin cases right out of the box. I don’t size them but I will give the primer holes a good look and clean up the flash hole with a .058″ bit in a pin vise. To fire-form, I seat a Berger 108gr BT .030″ into the lands over a standard 6mmBR load of Varget.
For match loads, I use Alliant Reloder 15. While Varget is less sensitive to temp changes, RL15 has given me lower extreme spreads and better long range control. [Bob acknowledges that every barrel is unique, so a different powder, such as H4895 might work better for you.]
I clean my fired cases with stainless steel media in a Thumler’s rotary tumbler after every firing. I anneal after every other firing using a Bench-Source machine which is very well made and easy to operate. I use a Whidden full length bushing die with Redding bushings for sizing.
After sizing, I chamfer the inside of the neck with the K&M tool which has a pilot rod centered in the flash hole. Then I’ll give the neck and mouth a “once over” with some 0000 steel wool. I finish loading off with a Redding Competition Seating Die with the micrometer top.
I use a carbide ball on the expander rod of the full length sizing die. I use a .266″ TiN-coated bushing and the ball just kisses the inside walls of the sized neck. I get very consistent neck tension this way and have had no issue with split necks.
Seating Depth Considerations
With fire-formed brass, the junction of the bullet’s bearing surface and boat-tail is above the neck/shoulder junction of the case, so I have no issues with donuts. You can see how a loaded round looks in the photo at left. For occasional trimming, I use a very nice little Possum Hollow trimmer that indexes on the case shoulder.

Here’s a tip for guys who shoot the 6 PPC, 6 Dasher, 6 BRA, .284 Shehane, or other wildcat cartridges that require fire-forming. Use your fouler shots to fire-form new cases. That way your fouler shots do “double-duty” and you get your brass fire-formed without putting extra rounds through your expensive barrel.
This procedure is recommended by Joel Kendrick, the 2004 IBS 600-yard Shooter of the Year. After he cleans his barrel, Joel knows it takes two or three shots to foul in the bore before accuracy returns. When shooting his PPC, Joel uses those fouler shots to fire-form his new brass. Joel explains: “I like to have relatively new brass always ready. By fire-forming a couple cases after each barrel-cleaning during a match, by the end of the weekend I’ve got a dozen or more freshly fire-formed cases to put into the rotation. If you do this with your fouler shots you get your fire-forming accomplished without using up any extra barrel life.”
This not only saves barrel wear, but it saves you trips to the range for the purpose of fire-forming. We thank Joel for this smart suggestion. For those who do not have a dedicated barrel for fire-forming, this should help keep your round-count down. Note: With this fouler fire-forming routine, you should ALWAYS do the fire-forming with the SAME POWDER you load for your match ammo. Joel currently works as the Supplier Quality Process Engineer for MMI-TruTec, a company that offers barrel surface coatings that can further extend your barrel life.

While there are many very, very talented women shooters, it’s still a bit unusual to see many ladies on a long-range firing line. It’s even more unusual to find a women shooter who regularly beats all the “good ol’ boys”. This week we feature Katy from California, who has competed in Varmint Silhouette matches with a very stylish and accurate Stolle 6BR. Along with husband/spotter Don (who shoots a 6mm Dasher), she has been one of “Top Guns” at the popular Pala Shooting Range in North San Diego County. Here’s a view of the Pala facility, looking down-range at the rows of silhouette targets:
Pala — A Mecca for Southern California Shooters
Near the Indian Casino and Resort in Pala, California is one of the longest rifle ranges in the state. Pala hosts a wide variety of shooting matches — cowboy action, lever action silhouette, black powder silhouette, hi-power silhouette, tactical pistol and rifle matches, to name a few. The black powder buffalo and tactical rifle matches use the longest range with 900-meter targets. Katy and her husband Don have competed in Varmint Rifle Silhouette matches, which were held monthly in years past. Range Info: Range.palatribe.com.
Katy tell us: “These Varmint Silhouette matches are a lot of fun! It’s very satisfying to see the little critters fly off the rail. A good spotter will note how the target flies when hit–‘Did it turn right or left? Did it lift up or fall back?’ Steel targets reveal more about real world ballistics than just a hole in a piece of paper. And nothing beats reactive targets for fun shooting.”
For Katy and Don, shooting is a family affair: “I started shooting the varmint rifle silhouette at the encouragement of husband Don. He bought/built himself a 6mmBR to shoot the varmint rifle match and re-barreled an old Hart-sleeved Remington 700 to fast-twist .223 for me to use. I did pretty well for a beginner, winning a match after just a few months of competition. Winning with that .223 had competitors scratching their heads. Frankly, it was just a fortuitous combination of great spotter, steady hold, and a good rifle. That .223 was certainly a very accurate piece. I always expected the bullet would hit right where the rifle was aimed, if we called the wind right. But like all good things, with time the .223’s accuracy began to fade. As the barrel finally gave up the ghost, a replacement was ready–a bright red Panda bear chambered in 6mm BR.
Beating the Guys at their Own Game
With my old .223, I won five varmint matches between December 2000 and April 2002. I also won my class (Master) in June, 2001. However, with the 6BR Panda, I shoot higher scores and have now had four match wins between May, 2003 and August 2004. And I won my class twice in 2003. Over time, as our competitors’ skills and firearms have improved, the criteria for shooter classification has been upgraded. Originally, one could miss 10% of the animals and qualify as a “Master” shooter. A few years ago, the criteria was tightened to 5% misses to earn “Master” status. This 6mmBR has kept me up in Master class.
I’ve done well enough with my little Red Panda that folks have been asking me about my shooting technique. Both Don and I shoot free recoil. We keep everything off the rifle except the trigger finger and thumb. Keep your shoulder back from the butt, and make sure your cheek doesn’t contact the stock and that your shooting cap doesn’t hit the scope. Fine-tune your elevation by squeezing on the rear bag. I use a front rest forearm stop to keep the rifle in the same place on the front rest. After firing, pushing the rifle back against the front stop usually verifies rifle tracking and allows a quick check of how far off the sighter shot’s impact was from point of aim.”
The Female Perspective — Katy’s Views on Shooting
We all know women can be crack shots. The little lady in the picture proved that more than a century ago. Competitive shooting is one of the few sports where women can and do compete head-to-head with men — and often win. [Amanda Elsenboss recently won the National High Power Championship and the National Long Range Championship. And Nancy Tompkins and her daughter Sherri Gallagher have won National shooting titles.] But the fact remains shooting is still very much a male-dominated sport. Here are some of my thoughts on how that might change.
Beneficial Aspects of Shooting
The first and most important benefit of competitive shooting is learning to handle a rifle/firearm safely. We’re well past the time when women should have conquered their fears of guns. An added benefit would be increasing a woman’s ability to respond to any threats. I remember when I was in college and we took my anti-gun roommate out to the range for a shooting lesson. She had a great time shooting away. She learned that firearms are not just “scary”, but also an enjoyable tool.
How to Get More Women Involved
Since we aren’t going to get the silencer legislation changed to improve women’s enjoyment of the sport, we will have to promote other aspects of shooting. I think shooting sports can increase self-confidence, giving women a sense of accomplishment and inner strength to remain calm under stress. It is very satisfying to see a positive result (at very long distance) of your focused efforts. Developing skill at any sport can improve one’s self-image and coordination. Encourage the women in your life to join you at the range. Believe it or not fellows, your wives and girl friends like to spend time with you. At Pala, some of the wives make the best spotters, even though they don’t shoot.
I find these varmint silhouette matches ideal from the standpoint of a woman’s participation. First, you get to lay down and shoot–that’s much more relaxed than classic position-shooting. Second, the really heavy rifle is supported on front and rear rests so that all you need to do is carefully guide the rifle, concentrate on the sight picture and pull the trigger when everything lines up. And, by the way, I clean house and prepare the meals, while my husband Don cleans the rifles and prepares the ammunition.
Dealing with Noise Pollution
The first thing a women notices at the range is how much noise these rifles make. How can anyone carry on a decent conversation, much less think with all the racket? Practice days are the worst–there is just constant gunfire with very few ceasefires. Matches are fine, because there is only gunfire during warm-up and then for 8 minutes during each relay. On the firing line, I wear both fitted earplugs and ear muffs to tolerate the decibels. Being heard and understood is always a problem during the match.
Shooters’ Techno-Babble–I Guess It Really Is a “Guy Thing”
One of my fellow female shooters commented that, at the range, the guys never seem to talk about anything but firearms and their accouterments at the range. Although I am familiar with the term “minutes of angle” I have gotten sloppy in my speech and generally just report how many clicks one needs to adjust for the wind or the sighter shot. Reading Don’s equipment discussion confused me when he kept referring to MOA. I have been with non-shooting friends several times when knowledgeable shooters start talking firearms. It is as if they are speaking a different language, and my friends look to me with a puzzlement on their faces. Well, in fact it has its own language and I think I’m getting finally getting able to speak it.
Katy’s 6BR — Technical Primer by Hubby and “Loadmaster” Don
Way back in 1990 a Precision Shooting magazine “Trading Post” advertisement offered a low-mileage, Panda-actioned .262″ neck, 6mm BR rifle and all the reloading accouterments. This light-varmint class rifle was built in the mid-1980’s around an unusual round Panda action with straight-fluted bolt. As configured, the gun had performed very well indeed–shooting many groups in the zeros. The action is glued into a Lee Six thumbhole BR stock and uses externally accessible pins to hang the 3 oz. trigger. The scope is an older 36X Leupold BR model, held by Kelbly rings on a Davidson base. The original barrel was a 4-groove, 14-twist, apparently made by Pat McMillan. A hand-written information tag taped to the underside of the barrel was discovered upon its removal, and indicates the barrel was fitted by JACO, April 1986. Anyone know who that is?
The 14-twist barrel could not stabilize any bullets greater than about 80 grains. It would keep an 80-grain Starke inside 0.4″ at 200m with a velocity of 3120 fps using 31.8 grains of Varget. However, the 80-grain bullets were blown all over by the winds out to 500 meters.
Past success with Pac-Nor pre-fit barrels inspired me to order a 28″, 4-groove, 8.6″-twist barrel chambered with their .262” neck 6mm BR reamer. Pac-Nor crowned and chambered the barrel; and, in this case, threaded it to fit a Panda action. After we installed the barrel on the action, we found that the bolt nose touched the conical barrel breech face. 0.010” needed to be removed from the cone face so that the bolt closed with a perfect fit. Headspace is now just right at 1.167″.
Load Development
My experience with a couple of other fast-twist 6BRs, one also chambered with Pac-Nor’s .262″ reamer, suggested that the 95gr Berger VLDs would work well the estimated 0.060″ freebore in Katy’s rifle. The goal was to get 2800-2900 fps velocity with inherent accuracy no worse than half the smallest silhouette size. That meant we needed a load that delivered repeatable 0.4 MOA accuracy or better.
A new batch of Lapua 6mm Norma BR brass was neck-turned to 0.0083″ wall thickness to fit the chamber and fire-formed during barrel break-in, following Pac-Nor’s guidelines. We tried a bunch of different moly-coated bullets at 200 meters, most with moderate charges of H322. The results of the bullet-testing ranged from poor (over an inch) to astonishing (68-grain, flat-base Eubers over 29.7 grains of H322 went into about .25″ at 200 meters!) But these flat-based bullets lacked the high ballistic coefficient we wanted for the varmint silhouette match. So we tried the 95-grain VLD Bergers (0.5+ BC) and produced several good loads, all sparked by Federal 205m primers. The best load seemed to be 28.2 grains H322 at 2860 fps, followed by 30.4 grains N135 at 2920fps, and 31.0 grains of Varget at 2890 fps.
All loads shot better than 0.4 MOA, but the H322 seemed a little more accurate, and about twice as much H322 was on hand. So, after about 120 shots the barrel was conditioned, brass formed and a match load selected for the 95 VLD Bergers. Bullets are seated about 0.010″ into the rifling for a typical cartridge LOA of 2.325”, which puts the heel of the 95 VLD boat-tail just below the case neck-shoulder line. Cases are sized with a Wilson neck bushing die that works only the upper 2/3 of the case neck to support the bearing surface of the seated bullet.
Don’s Handy Guide to Varmint Silhouette Shooting
Varmint Silhouette–Origins and Basics
Over a decade ago, a metallic silhouette match was devised for typical varmint rifles at the North County Shootist Association range near the hamlet of Pala, in north San Diego County, California. The course of fire used the conventional rifle silhouette range with banks of 10 special varmint targets sized 0.8 to 1.0 MOA (Minute of Angle) in width. At five different yardages, ten steel “critter” targets are set as follows: 200 Meters – Field Mice (“pikas”); 300 meters – Crows; 385 meters – Ground Squirrels; 500 meters – Jack Rabbits; 600 yards – Prairie Dogs. The folks at Pala run a tight ship, cycling multiple relays efficiently, so everybody gets to shoot 50 targets (10 each at five different yardages), and the show is usually completed by 1:00 pm. There’s a one-hour sight-in period starting at 8:00 am, and the match starts at 9:00 am sharp. Newcomers should definitely arrive no later than 7:45 am, because you may need that full sight-in period to acquire solid zeros at all five yardages.
Firearms are limited to field-portable, varmint-caliber rifles in either custom or factory class, and having a maximum 6.5mm bore, but bullets must weigh no more than 107 grains. You can shoot prone or from a bench using a front rest and bag rear. For more information, visit Range.palatribe.com.
Match Rules and Shooting Procedures
Matches are fired as a team — shooter and spotter. The course of fire typically consists of 10 steel, knock-down varmint animal targets at each of the five distances. After firing a sighter, targets are taken from left to right, one shot per target. Missed targets remain standing. Any target struck out of sequence is also a “miss”. The shooter’s objective is to sequentially knock-off (clean) all 10 targets. The spotter’s duties are to support the shooter in all aspects of shot preparation. First and foremost, the spotter tries to see each shot impact and call appropriate windage and elevation adjustments for the shooter. In shifty conditions, a good spotter is vital.
Let’s start at the beginning. Before the match there is usually an opportunity to fire a few fouling shots and check sight settings for load and distance. An initial read on conditions–mostly wind direction, strength and consistency–is also made. The spotter should checklist the shooter to make sure they are set up for the relay distance and have adjusted their sights to the correct elevation and windage.
It could be argued that for the shooter, the first shot at a given distance, the sighter shot, is the most important shot fired. Since the sighter targets are fixed (don’t fall over) and freshly painted, bullet impact is obvious to both shooter and spotter. If the bullet hits where expected–point of aim–the spotter then tracks and calls observed changes (mostly wind) relative to the shooter’s initial scope settings. If point of impact shifts on subsequent record targets or the shooter misses, appropriate sight adjustments are recommended to the shooter. Admittedly, it is sometimes difficult or impossible to see the point of impact on these small, reactive targets. However, an estimate of bullet strike can be made from target behavior such as rotation and/or impact trajectory.
The Guacamole Connection
Katy and Don are avocado farmers. From time to time they’d bring a few avocados to the range to give to the other shooters. In addition, on some months, Katy would bring some home-made Guacamole made from the avocados on their ranch. Katy says “Fellow shooters appreciate a batch of guacamole so much they bring their own chips to go with the dip. I keep getting suggestions that I go into the business of making and selling guacamole. Guess I could start by selling it at the range.”
Katy’s Guacamole Recipe
4 ripe avocados, peeled and pitted
1/2 lemon squeezed (I use Meyer lemons, lime juice is also good)
1/2 cup fresh salsa — your favorite variety
1 tsp garlic salt or fresh garlic chopped
All of the above quantities can be adjusted for taste. Mash the ingredients with a potato masher. Serve with chips, fresh vegetables (carrot sticks, celery, broccoli), or as garnish for tacos, burritos, taquitos, etc., and as special treat – spread on warm buttered toast for breakfast.
Good Shooting and Bon Appetit! — Don & Katy

This week’s featured firearm belongs to John “SnakeEye” Seibel, founder of the VarmintsForFun website. In recent years, John has become a “true believer” in the little 20-Caliber cartridges. He says this light-recoiling 20 PPC, Rampro-actioned pistol is perfect for a quick shot on a critter, taken from the front seat of his truck. John tells us: “A long-range pistol is an ideal truck gun in my opinion. It stows in a small area and doesn’t take up the room a rifle does. Just keep ear protection near by at all times! I’ve taken varmints as far as 400+ yards with this 20 PPC pistol, so why would you need a rifle?”
Perspectives on Pistols for the Varmint Hunter
by John Seibel
I decided to try my hand at shooting varmints with a pistol one day when I grew tired of wrestling a rifle around in the truck for a quick shot. Many times when traveling around on the farm you’ll spy a groundhog or fox that usually isn’t more than 200 yards away. A single-shot pistol like the Thompson Contender could fit the bill. With its compact length, around 20 inches, a long-barrel pistol can lay on the truck’s passenger seat for easy access. I usually keep my two leather brick-style sandbags laying beside the console and seat. I have a box made from hard rubber that I lay across the top of the door. I then lay the two bags on top. This makes a nice platform to rest the pistol’s forearm. I like to use a forearm that is at least two inches wide. That lets the gun lay steady—almost like you are shooting from a bench rest. For the shooting hand, I prefer a pistol grip with finger grooves and a slight overhang or flare for the web of your hand.
As for optics, I tried long-eye-relief pistol scopes but they lacked the magnification you need for long-range target shooting or varminting. Those pistol scopes have really long eye-relief because they are designed to work with the pistol held at arm’s length. When shooting at the bench or from a truck that’s not what you want. By the time you find the target and get your eye in the exact location, the varmint has moved on or died of old age! After much fiddling around with pistol-type scopes, I finally decided to use rifle scopes on my long-range pistols. The minimum I use is a 4.5-14×40. Eye relief on a Leupold 4.5-14x40mm is about 3.5 inches at 4.5 power. Field of view is better with rifle scopes too and it’s easier to acquire your target. For this type of shooting a light-recoiling caliber is essential or you will have scope-eye bad! I currently have three long-range pistols and use them to shoot 17M4, 20 PPC, 22 BR, and .223 Rem. The featured gun may be the most accurate of my pistols, and your editor thinks it’s the most handsome of the three.
The Rampro Pistol Project — Working with John Illum
A couple of years ago I called John Illum of Rampro about building the ultimate long-range pistol. It just so happens that John was a big time long-range pistol shooter. I told him that I wanted a gun that didn’t recoil badly and wouldn’t torque when fired. As I am a quadriplegic, with no grip in my hands, the gun had to handle well under recoil so I didn’t drop it. Recoil had to be straight back–no twisting.
Well Illum listened to me and came up with a gun that performs just the way I wanted. Illum suggested a rear grip stock of his own design. It has a 2.25″ wide forearm and a rear grip with a slight palm swell that fits your hand perfectly. Another nice feature is the finger grips. It has an extended overhang or “beavertail” that fits comfortably in the web of your hand. Of course it had to be walnut! I chose Rampro’s STP small action with a PPC bolt. His bolt uses a Sako-type extractor. The action is a single-shot. Being right-handed, I chose a right bolt, left port configuration. This works really well in a pistol. You can load with your left hand and see the round laying in the action–that’s what you want in a pistol without a safety.
Gun Specifications John Illum’s Rampro actions are chrome-moly steel. Commonly you’d see them blued, but I had him put a brushed nickel finish on the action and rings. From a few feet away it looks like stainless. The trigger is Illum’s own design set at 8 ounces, and there’s no creep that I can detect. The action has Remington barrel threads and will accept Remington type triggers. One neat thing is that the action was milled with an integral recoil lug (much like the current Surgeon Action). And the bolt is milled all in one piece–no soldered-on handles. My only gripe with this bolt handle is that it could be a tad longer, but it still is manageable for a single-shot. You’ll also note how slick and streamlined the scope rings are. Illum made those as well. His rings mount to the action via two screws from the inside of the ring, a very elegant set-up for sure. (I currently have a 6.5-20x40mm Nikon scope on this gun. If I had to do this project over again the only thing I would change would be installing a 30mm scope because I like ‘em!).
The barrel is a PacNor Super-Match heavy taper with flutes milled by John Illum, who did all the gunsmithing on this pistol. Twist rate is 1 in 12 inches, with an 11° crown, polished to a mirror finish. The barrel was bead-blasted on the exterior to cut glare. I had Illum cut a 20 PPC minimum-spec chamber, with a .237″ neck. That way I don’t have to turn necks on the Lapua Brass (220 Russian necked down to .204). This is a varmint gun–there’s no need for turned necks. [Editor’s Note: Rampro is no longer in business. However, John tells us “I haven’t had any problems with the action so far. If I did, most competent gunsmiths could fix them easily.”]
Handgun Handling Tips
If you want to shoot a long-range pistol but have never have shot this kind of gun before, try to find a mentor — someone with a gun like this who can school you a bit in the correct technique. The first thing you notice is that you have no comb or cheek piece to help align your head and neck. And getting used to the optics takes some practice. Most people fit a pistol-type (long eye-relief) scope, but these can be awkward to use, and somewhat frustrating at first — the field of view is very restricted. Move your head very slightly and you can lose the sight picture completely. You can solve that problem by using a standard rifle scope, but that will put your head very close to the eye-piece — just three to four inches. With that arrangement, if you don’t hold the gun correctly … POW instant scope-eye!
Now once you get the hang of shooting a long-range pistol you will find it can be just as accurate as a rifle. But there is a trick to shooting them. Shooting a long-range pistol is a whole new world — you need to hold it just right. If you don’t let the gun roll back a little (i.e. if you grip too hard) you will get vertical stringing. I hold my hand against the back of the grip to guide the gun but let it almost free recoil. Looking at how compact the pistol is, you might think “Hey, this would make an ideal ‘walking-around’ varminter.” Well, that’s not really the case. For real precision shooting a solid benchrest type set-up is a must. You can attach a bipod to a long-range pistol, but you would need a flat surface. A fence-post top would work pretty well without a bipod if you carry a small light bag. Overall though, this type of pistol works best as a sandbag gun. For a walking-around gun, you’d be happier with a rifle I think.
Load Development and Accuracy
When I built this gun, Hornady had just released the 32gr V-Max (see footnote), a good match for my barrel’s 1:12″ twist. I choose the 20 PPC because of the very good Lapua brass (220 Russian parent case). I figured teaming Lapua brass with the little .204 bullet would offer excellent accuracy combined with very low recoil. My expectations were fulfilled. The brass proved to be excellent and the PacNor loved the little V-Max pills.
I tried quite a few different loads and most powders that I tried worked very well. These included: H322, Benchmark, AA 2460, and Reloader 7. Amazingly, with just 14″ of barrel, all of these powders delivered impressive velocities–ranging from 3914 to 4074 fps. I settled on 48 Harrell’s clicks of Accurate Arms (AA) 2460, which drives the 32gr V-Maxs to 3995 fps.
With AA 2460 the gun will shoot in the low 3s at 100 yards consistently — as long as I steer the gun right, which takes some practice. I think groups in the low 0.3″ range is excellent for a non-benchrest factory bullet. Despite having no buttstock to grab, recoil on my 20 PPC pistol is very minimal — it just rocks back into your hand. The main problem is to keep the scope from smacking you, since I used a rifle scope with short eye-relief. Muzzle flash and noise are tolerable but DO NOT shoot one of these without good ear protection. Your ears are very close to the muzzle.
I also have a 20 PPC rifle built on a BAT action with a Richard’s #008 laminated stock cut down in size. That gun’s 1:9″-twist Lilja barrel lets me shoot the Berger 50gr LTB bullets. In the wind, these perform quite a bit better than the 32s. My two favorite loads for the 50 grainers are: a) 26.0gr VV N135, CCI 450 primers, 3615 fps; and b) 27.3gr Hodgdon Varget, CCI 450s, 3595 fps. The BAT 20 PPC also shoots really well with the 40gr V-Max, pushed by N135 and Fed 205M primers.

One important thing to remember if you build a pistol is to make sure the receiver came from the factory as a pistol and was titled as a pistol. Rifle actions are illegal to use as a pistol. Yes, that’s a nonsensical law, but it’s still on the books. You can use factory pistol actions such as the XP 100.
If you want a new custom action such as a BAT (my favorite), you can order it as a pistol action and when you get it, register it as a pistol. Note, in some states there may be additional fees, waiting periods, or restrictions for pistol actions (as opposed to rifle actions). Check your local laws before ordering the action.
Future Trends in Varmint Hunting — Plenty of Twenties
I think these sub-caliber rounds, both 20s and the 17s, are the future of recreational varminting, at least out to medium distances. The Twenties offer low recoil, excellent accuracy, and components keep getting better and better. The bullet-makers are finally making high-quality bullets in appropriate weights. Compared to something like a 22-250, I’ve noticed that my 20 PPC rifle has a lot less noise, a plus when you want to be quiet around other people and varmints.
The flat trajectory is another big advantage in the field. With the 20 PPC, zeroed at 100 yards, I can pretty much hold dead center and get hits out to 300 yards or so without touching the scope to add elevation. [Editor: The same is true with the 20 Practical cartridge, basically a .223 Rem necked down to .20 Caliber. It has proven very accurate and easy to tune.]
The 20-Caliber cartridges we have now, in particular the 20 PPC and 20 BR, are very well-refined. You don’t have to do a lot of tuning or tinkering to have a very accurate, effective varmint-slayer. In fact, if I could dream up a signature “20 VFF” (Varmints For Fun) cartridge it would basically be the 20 PPC. In truth, nearly any of the popular 17- or 20-Caliber cartridges will perform well if you start with top-quality brass. The sub-calibers have less recoil and burn less powder, and there are very good components for most varmint and target-shooting applications. To me it seems that these small calibers work so well because of good components, low recoil, and efficient cartridge designs (particularly in the VarTarg and PPC cases).
WARNING: For your own safety, ALWAYS reduce all starting charges by 10% and work up carefully! Ambient temperature changes, powder lot variations, and differences in barrel friction can result in significantly increased pressures.

Here’s a tip for guys who shoot the 6 PPC, 6 Dasher, 6 BRA, .284 Shehane, or other wildcat cartridges that require fire-forming. Use your fouler shots to fire-form new cases. That way your fouler shots do “double-duty” and you get your brass fire-formed without putting extra rounds through your expensive barrel.
This procedure is recommended by Joel Kendrick, the 2004 IBS 600-yard Shooter of the Year. After he cleans his barrel, Joel knows it takes two or three shots to foul in the bore before accuracy returns. When shooting his PPC, Joel uses those fouler shots to fire-form his new brass. Joel explains: “I like to have relatively new brass always ready. By fire-forming a couple cases after each barrel-cleaning during a match, by the end of the weekend I’ve got a dozen or more freshly fire-formed cases to put into the rotation. If you do this with your fouler shots you get your fire-forming accomplished without using up any extra barrel life.”
This not only saves barrel wear, but it saves you trips to the range for the purpose of fire-forming. We thank Joel for this smart suggestion. For those who do not have a dedicated barrel for fire-forming, this should help keep your round-count down. Note: With this fouler fire-forming routine, you should ALWAYS do the fire-forming with the SAME POWDER you load for your match ammo. Joel currently works as the Supplier Quality Process Engineer for MMI-TruTec, a company that offers barrel surface coatings that can further extend your barrel life.

Can you form a wildcat cartridge such as the 6mm Dasher or 6 BRA (BR Ackley) without expending primer, powders, and bullets? Absolutely. Using the hydro-forming method you can form improved cases in your workshop with no firing whatsoever, so there is no wear on your precious barrel. Watch this video to see how it’s done for the 6 Dasher:
6 Dasher Case Hydro-Forming Demonstration:
Forum member Wes J. (aka P1ZombieKiller) has produced a helpful video showing how to form Dasher cases use the Hornady Hydraulic forming die kit. This includes a two-part die (body and piston), and a special shell holder. To form the case, you insert a primer in your virgin brass, top the case off with with a fluid (water or alcohol), then run the case up into the Hydro-forming die. A few stout whacks with a hammer and your case is 95% formed.
Hydro-Forming Procedure Step-by-Step:
1. Insert spent primer in new 6mmBR brass case.
2. Fill with water or alcohol (Wes prefers alcohol).
3. Wipe excess fluid off case.
4. Place case in special Hornady shell-holder (no primer hole).
5. Run case up into Hydraulic forming die.
6. Smack top piston of forming die 3-4 times with rubber mallet or dead-blow hammer.
7. Inspect case, re-fill and repeat if necessary.
8. Drain alcohol (or water) into container.
9. Remove primer (and save for re-use).
10. Blow-dry formed case. Inspect and measure formed case.
Wes achieves very uniform cartridge OALs with this method. He measured ten (10) hydro-formed 6 Dasher cases and got these results: two @ 1.536″; 2 @ 1.537″; and 6 @ 1.538″.
Three or Four Whacks Produces a 95%-Formed Case
With a Hornady hydro-forming die, hydraulic pressure does the job of blowing out the shoulders of your improved case. The process is relatively simple. Place a spent primer in the bottom of a new piece of brass. Fill the case with water, and then slip it into a special Hornady shell-holder with no hole in the middle. Then you run the case up into the forming die. Now comes the fun part. You gently insert a plunger (hydraulic ram) from the top, and give it three or four stiff whacks with a mallet (or better yet, a dead-blow hammer). Remove the plunger and you have a 95% formed case, ready to load.
Special Shell-Holder
Hornady supplies a shell holder made specifically for the hydro die; there’s no hole in the bottom of it. Just insert a spent primer into the primer pocket and you’re ready to go. The spent primer, combined with the solid shell holder, keeps the water from seeping out of the primer pocket. The primer pushes out a little bit during this process, but it’s impossible for it to come out because of the way the shell holder is designed. The shell holder has a grove which allows the case to slide out of the shell holder even when the primer protrudes a bit.
Another Option — Hydro-Forming by DJ’s Brass Service
If you want to hydro-form your brass to save barrel life but you don’t want to go through the effort, or purchase the hydro-forming dies, there is a very good option. Darrell Jones of DJ’s Brass Service will do the job for a modest charge. You send Darrel your brass and he does all the hard work, preparing perfectly formed brass. Darrell can also anneal and/or neck-turn your cases — all for a reasonable fee.
DJ’s Brass Service offers case hydro-forming to your exact specs. Darrell Jones offers this service for a variety of popular cartridges: 6 PPC, 30 PPC, 30 BR, 6 BRA (BR Ackley), 6mm Grinch, 6 BRDX, 6 BRX, .260 Ackley, .284 Shehane and of course the very popular 6mm Dasher. After hydro-forming your brass, Darrell can also neck-up or neck-down the cases to meet your needs. For example, if you shoot a 22 Dasher, Darrell can hydro-form the cases to a 6 Dasher and then neck them down to .22 caliber. He can also turn the necks to your specs (for an additional charge). Hydro-forming by Darrell costs $0.60 (sixty cents) per case with a minimum order of $60 per hundred. NOTE: After cases are hydro-formed by Darrell, every case is washed, cleaned, and re-annealed. This cleaning and annealing process is included in the $0.60 (sixty cents) per case price.

Chris Nichols with potential world record (1.297″ 4-Target Agg) Heavy Gun Targets!
Report by Bart Sauter, Bart’s Custom Bullets
Chris Nichols is one of the best 600-yard shooters in the game. This 2019 season he compiled one of the most impressive mid-range benchrest seasons ever. Check out the stats — Chris’s nine-match, Two-Gun Group Aggregate (Agg) for the year is 1.983″! That’s under two inches average at 600 for 72 record targets fired in competition. Many 600-yard shooters aspire to shoot a single, 4-target Agg that measures 1.983″, but doing that for 72 targets is amazing!
And of the nine matches Chris shot, he took SIX Overall Two-Gun wins — a 67% win ratio. And in the process Chris also shot what is possibly the smallest 4-target Heavy Gun Agg ever recorded — 1.297 inches. Hey readers — that Agg works out to 0.206 MOA average group size — well under quarter-MOA for four, 5-shot groups at 0.34 MILES (600 yards)!
Chris with 0.665″ group at 600 yards. This is the smallest HG group fired in the IBS in 2019.
The Equipment: 6mm Dasher Light Gun and Heavy Gun
Chris likes to run 1.550 stainless steel Bat “B” actions, Jewell triggers, Brux or Bartlein barrels. He prefers wooden stocks as he feels they produce a better resonance for Long Range rifles. Chris has his own stock design crafted by Johnny Byers. Imagine a Wheeler LRB stock front half mated with an McMillan ST 1000 rear section and you have Chris’ stock! It features a Wheeler-type, 4″-wide fore-end with an ST 1000 low-comb profile in the back. Both Light Gun and Heavy Gun sport Vortex 15-60x52mm Golden Eagle scopes mounted with Harrell’s double screw tall rings. Chris does NOT use either muzzle brake or tuner.
Here is Chris at his home range with his Light Gun (17 lbs. max).
Chris Nichols’s Heavy Gun is a true heavy coming in at around 42 pounds. It was responsible for the HG Agg of 1.297″ (potential new world record). His season-long aggregate with his Heavy Gun was 1.861″ for 36 targets! This rifle has similar components as his Light Gun, except the barreled action rides in a barrel block in a McMillan HBR 50 BMG stock.
Both rifles ride a top of a Sinclair competition rest with a Protector DR Flat Top rear bag. When Chris goes to HG gun he simply switches tops (made by Daniel Greenlaw) on his front rest to accommodate the larger forend. As Chris says ,” This keeps things simple and exactly the same. ” Just the way he likes it.
Reloading for the 6mm Dasher
Chris’s load choice for both LG and HG is Hodgdon Varget pushing 105gr Berger VLDs. He uses CCI 450 primers, seated with an old Lee hand primer. When it comes to reloading, Chris likes to keep things as simple as possible. “If people saw me reloading they’d probably laugh!” Chris revealed that he doesn’t anneal or clean his cases. He just sprays them down with Hornady One Shot Case Lube, resizes, then runs a brush down the necks, and cleans the primer pockets. The only cleaning his cases get is when he wipes the lube off of them. Chris WILL trim and chamfer as needed.
Chris says seating consistency is critical — he uses a K&M Arbor press with force dial indicator. I asked if there were certain numbers he looks for when seating. Chris replied, “I’m only concerned with consistency and not a certain number, 5 pounds or 60 pounds. It doesn’t matter as long as they are the same. I take what the brass gives me.”
Tuning the 6mm Dasher for Record-Setting Accuracy
I asked Chris what was special about his Dasher and how he kept it tuned and so competitive? His reply is something all shooters should pay careful attention to: “[Success] starts with having a good reamer, bullets and barrels. But more than that, it’s KNOWING your Cartridge, KNOWING your bullets, and KNOWING your barrels! I’ve shot it so much I just know what to do. I’m comfortable with it. I know how to get it to shoot and when it’s not, I have a pretty good idea how to get it back in tune. Once you know your equipment, then you can learn how to get the most out of it.”
Chris has a range at his house and he tunes at 300 yards. He looks for consistent, 300-yard 5-shot groups of 0.600″ or less! He wants to see nice round groups! Not groups with four in and one out or vertical strings. Chris starts by finding “touch” (to the lands) then he moves the bullets .002″ off the lands and begins tuning. Chris has found that usually somewhere around .008-.012″ off the lands is where his Berger 105gr VLDs shot best. I asked Chris what’s the biggest factor contributing to his success? He said, one big thing was that he can do his own work. That’s a huge advantage.
Look for Accuracy First, Velocity Second
Early on Chris had it in his mind that for a 6mm Dasher to shoot best he needed to achieve a certain velocity range — 2990 to 3030 FPS. The problem was he wasn’t paying attention to what the target was telling him. He’d get to the speed he was looking for but the accuracy wasn’t there. Once he started slowing the speeds down and giving the barrel what it wanted, then the accuracy came! Also with the slower speeds came better consistency.
Chris Nichols’s Tuning Tips for 6mm Dasher:
• Take consistency over speed.
• Only change one thing at a time and run it to the ground.
• Every barrel is a little different, so give it what it wants.
• Pay attention to what your target is telling you.
• Don’t be afraid to REDUCE your powder load.
Chris Nichols’s Advice for New Shooters
Chris says the best thing a new shooter can do is align themselves with knowledgeable people, and if they will talk, listen! Next, be ready to buy the best equipment or be ready to buy it twice. Chris also says: “Don’t cheap-out on sighters. Sighters need to be just as good as your record rounds.”
In the Beginning — Learning the 600-yard Benchrest Game
Chris’s shooting career began in 2012. His first win came in 2014. He was shooting beside guys like Sam Hall, Larry Isenhour, Mike Hanes, Jeff Godfrey James Coffey, and Chad Jenkins, who are very tough competition indeed. He said when he won he was ecstatic and he’ll never forget it! That first trophy had him feeling like he’d just won the Nationals! Chris shot a 6BR for the first two years of his career, before switching to the 6 Dasher. I asked him why he switched? He said, “guys were starting to shoot the Dasher and winning with it!”
I asked Chris if he had a mentor and he said, “not really”. He learned by watching the guys who consistently finished Top 5 at matches and occasionally asked them a question. Not two questions, just one! Chris didn’t want to push his luck by asking too much. Then Chris would take that information and test it and apply it to his own shooting. Chris says, “he learned mainly by the ‘school of hard-knocks’. The good thing about learning that way is it sticks with you!”
Chris Nichols 2019 600-Yard Win List and Statistics
With the 6mm Dasher cartridge becoming popular with PRS/NRL competitors as well as the benchrest crowd, we thought it was time to re-visit a special rifle chambered for the 6mm Dasher wildcat. This gun has a great story behind it. Forum member Bob A. (aka “Killshot”) used his “Forum Classifieds Special” to beat all comers in the F-Class Division in the American-Canadian Match and the Long Range Regional Match in 2013 in Sacramento, CA.
Bob’s 6mm Dasher sports a blue-printed Rem 700 action. Who says you need a high-dollar custom action to run with the big dogs? In fact, this same gun, built with components sourced from AccurateShooter Forum Classified Ads, set a Sacramento F-Class range record of 200-17X a few years back. In this story, Bob talks about the build, and he explains his methods for loading ultra-accurate Dasher ammo.
Bob’s Budget-Build Dasher F-Classer
I wanted to build a proper rifle for F-Open but needed to keep it simple and, well, cheap. I found a solid “base” to build on in the form of a Dave Bruno-built, “pre-owned” 6-6.5×47 Lapua that I located in the AccurateShooter Forum classifieds in late 2011. The base action was a trued and blue-printed Remington 700 receiver circa 1971 with a spiral-fluted bolt. It was in a Shehane ST1000 stock painted sky blue and had a Jewell 1.5-oz BR trigger. I sent the bolt to Greg Tannel (Gretanrifles.com) to have the firing pin hole bushed and sleeved, the ejector removed and the hole filled and the face trued. I upgraded to Tannel’s Light Steel firing pin assembly while it was out.
Having the working bits completed, I needed a barrel. So I went to the AccurateShooter classifieds again and found a 1:8″-twist, 30″ x 1.25″ (diam.) Bartlein with a 0.236″-land bore. I called Dave Kiff and explained my pursuit and he recommended his PT&G “world record” 6 Dasher reamer (.2704″ no-turn neck and .104″ freebore). A month or so later the reamer and gauges arrived.
I had the barrel chambered by Marc Soulie of Spartan Precision Rifles (510-755-5293, Concord, CA). Marc is a great builder and I’m pleased to call him a friend.
The rifle got its good looks from a Pennsylvania artist named Kenny Prahl. His Prahl Designs shop (724-478-2538) added the white ghost-flames over the existing sky blue metallic paint.
Looks Great, Shoots Better
Fire-forming showed great promise — ten-shot groups of half an inch at 200 yards were typical. I lost only one case to a split neck and the “blow lengths” are good and consistent. This was followed up with load development which saw 100-yard, five-shot groups in the .1s and .2s as the rifle showed its preference for Reloder 15 over Varget powder, and for CCI 450s over all other primers. The bullet of choice was the ever-popular Berger 105gr Hybrid Target.
In February 2012 I began shooting the Dasher in monthly club matches at the Sacramento Valley Shooting Center, the home range of a number of excellent F-Class, Benchrest and High Power shooters. Using a Farley Coaxial rest up front (also picked up from a WTB ad on AccurateShooter’s Forum) and an Edgewood bag in the back, I gradually improved my gun-handling to the point where I could shoot a respectable score. This was very different from the bipod shooting I’d done in the past in F/TR.
Dasher Loading Tips
My chamber is set up for blue box Lapua 6mmBR brass. My case preparation is straight-forward. I fire-form with virgin cases right out of the box. I don’t size them but I will give the primer holes a good look and clean up the flash hole with a .058″ bit in a pin vise. To fire-form, I seat a Berger 108gr BT .030″ into the lands over a standard 6mmBR load of Varget.
For match loads, I use Alliant Reloder 15. While Varget is less sensitive to temp changes, RL15 has given me lower extreme spreads and better long range control. [Bob acknowledges that every barrel is unique, so a different powder, such as H4895 might work better for you.]
I clean my fired cases with stainless steel media in a Thumler’s rotary tumbler after every firing. I anneal after every other firing using a Bench-Source machine which is very well made and easy to operate. I use a Whidden full length bushing die with Redding bushings for sizing.
After sizing, I chamfer the inside of the neck with the K&M tool which has a pilot rod centered in the flash hole. Then I’ll give the neck and mouth a “once over” with some 0000 steel wool. I finish loading off with a Redding Competition Seating Die with the micrometer top.
I use a carbide ball on the expander rod of the full length sizing die. I use a .266″ TiN-coated bushing and the ball just kisses the inside walls of the sized neck. I get very consistent neck tension this way and have had no issue with split necks.
Seating Depth Considerations
With fire-formed brass, the junction of the bullet’s bearing surface and boat-tail is above the neck/shoulder junction of the case, so I have no issues with donuts. You can see how a loaded round looks in the photo at left. For occasional trimming, I use a very nice little Possum Hollow trimmer that indexes on the case shoulder.

The 6BR Improved cases have become very popular in tactical competitions. In fact the Precision Rifle Blog reports that the majority of Top 10 PRS and NRL shooters are now running some version of the 6mmBR Norma case — such as the 6mm Dasher, 6BRX, or 6BR Ackley. In fact “40% of those ranked in the top 10 in either league were running a 6mm Dasher”. This short, fat 6BR improved case can push the 100-107gr bullets to 2950+ fps, a well-known accuracy node. Yes the 6mm Creedmoor and 6XC can push heavy 6mm projectiles faster to be sure, but there is a trade-off in barrel life. The 6BR Improved cases represent a “sweet spot” for the tactical game, offering outstanding accuracy, with less recoil than bigger cartridges, including the 6.5 Creedmoor.
The only real downside to the short/fat 6BR-based cartridges is that they can be finicky when feeding from a magazine, at least without some modifications to the follower and feed lips. There are kits that can help with this, but now there is an even better solution — a premium custom action designed specifically to feed the 6mm Dasher (and similar cartridges) from a magazine. This action, the Borden Super Short 6, was recently, unveiled on Facebook by PRS competitor John Hargett. This action, available in both right- and left-hand versions, features a dedicated new Super Short 6 (SS6) magazine optimized for Dasher-sized cartridges. The bolt has a shorter throw than a standard Rem short action. We think this new action could become VERY popular with tactical shooters, and varmint hunters.
John Hargett says: “Installing spacer kits or possibly having a nose dive in full-size .308 mag is in the past! This will fit all 700 stocks and chassis and AICS bottom metal. So no need to change what you are already using. Borden creates a masterful action at an extremely affordable price.”
Key Facts about the Borden Super Short 6 Action and SS6 Magazine:
1. Rem 700 Footprint — The Borden Super Short 6 action is internally tailored to the 6mmBR cartridge and its wildcats, but externally maintains Rem 700 action dimensions. This means the action IS compatible with the stock and chassis you currently own. And, the Borden Super Short 6 comes in both right-hand and left-hand versions, with PVD coating available (on action and/or bolt).
2. Rem Trigger Compatibility — The Borden Super Short 6 action works with Rem-compatible triggers, and the actions are specifically timed to work with trigger of your choice.
3. Dasher-friendly New Mag Design — The patent-pending Super Short 6 magazine is sized right for the 6mm Dasher and all the 6BR family. The follower and feed lips are configured to allow smooth, reliable feeding with no “magazine nose dives”. Even with the optimal design, the SS 6 magazine will work with all chassis profiles and bottom metal made for AICS-type magazines.
Here is the description from Borden Rifles website:
“The new action from Borden Accuracy (Borden Super Short 6) features a Rem 700 short action-compatible footprint with a shortened magazine well and shortened port set up specifically to reliably feed 6 BR, 6 Dasher, 6 BRA, 22 BR cartridges. The bolt has modified Borden bumps to aid in cycling in the dirty environment. The pictured action shows our standard bolt handle and tear drop knob. Production models will feature a handle that is threaded on the end so individuals can use their preferred knobs. I have been one of the individuals that developed the bolt timing and neutral handoff with the trigger for competition shooting to minimize rifle upset in the bags when closing the bolt. These actions will be available with either the neutral timed handoff or with about .03 to .035 inch cock on close. The cock on close option has much easier bolt lift that seems to be favored by PRS competitors. For now the bolts will have spiral flutes but future versions will have diamond flutes as an option. Development work will be done to also handle the .223 Rem and the PPC family.”
6mm Dasher and 6BR Wildcats Favored by Top PRS/NRL Shooters
1. The vast majority of PRS Shooters surveyed are now shooting a 6mm cartridge of some kind.
2. While the 6mm Creedmoor is still very popular, the 6mm Dasher is now the #1 cartridge among leading PRS and NRL competitors surveyed. (SEE Chart HERE)
3. If you include the 6BRX, 6BRA, and original 6mmBR cartridge along with the 6mm Dasher, this full family of short, fat cartridges is now used by twice as many top PRS/NRL competitors as the 6mm Creedmoor. And the 6.5 Creedmoor has really fallen from favor.

St. Thomas Groundhog Shoot, Report by Jonathan Trivette
Nestled at the base of a mountain in south-central Pennsylvania is the St. Thomas Sportsmen’s Association. On a cool Saturday morning you’ll find some of the area’s best shooters at the monthly Groundhog Match. The match attracts shooters from Virginia, Maryland, West Virginia, and of course Pennsylvania.
It may not be the longest-yardage match in the area, but it can be the one of the toughest. The range is sloped up the mountain a little so the winds can be very tricky. Often times the three wind flags at 200, 300, and 400 yards will all be blowing in different directions.
A Class for Everyone
St. Thomas’s Groundhog match has five different classes: Heavy (Unlimited) Custom, Light Custom, Heavy Sporter, Light Factory Sporter, and an AR Class. The Heavy Custom is any gun over 17 pounds while Light Custom is any gun up to 17 pounds. The Heavy Sporter is any factory gun that has a heavy/varmint barrel on it. The Sporter class is any factory rifle that has a light profile barrel on it. And the AR class is any AR style rifle. CLICK HERE for Match Rules.
Groundhog Match Format
Signups start at around 7:00 am the day of the match. During sign-up you’ll choose a bench from the 20 available benches. The cost is $15 per gun and you can shoot as many guns as you would like. I’ve shot as many as four different guns but that makes for a busy day. For the Heavy Custom and Light Custom you will shoot 5 shots for score at 200, 300, and 400 yards. In the Heavy Sporter class you will shoot 5 shots for score at 100, 200, and 300 yards. In the Sporter and AR class you will shoot 3 shots for score at 100, 200, and 300 yards.
The Targets feature a groundhog with scoring rings on the left side and 5 practice rings on the right side. Shooters get as many practice shots as they want, subject to a time limit. The three relays run 6 minutes, 6 minutes and 9 minutes respectively.
The match is very well-organized yet has a “laid-back” feel. The first relay starts at 9:00 am and the match is usually over around 1:30 pm. There’s a covered picnic table area for socializing with fellow shooters while waiting on your relay. They have doughnuts and coffee in the morning and usually have some very good chili and hot dogs (for lunch) in the concessions area.
Groundhog Match Results April 16, 2016
On Saturday the weather was perfect and conditions were very good early on. However, by the time the last relay rolled around, mirage made it difficult to see. Ben Brubaker obviously had less trouble than most finishing 1st (143.02) and 2nd (143.02) in the Heavy Custom Class and 1st (144.04) and 3rd (142.04)in the Light Custom class using a 6mm Dasher in both classes. Bob Daron won the Heavy Sporter class with a score of 144.04 followed by Fred Kaminsky with a 142.06. Sporter class proved to be a family affair, with the Bollinger brothers, Glenn (87.01) and Bob (83.02) finishing first and second. We had one junior shooter on Saturday, 7-year-old Lydia Funk. The talented yound lady shot a 68 in Sporter class with her .223 Rem.
You may have missed the first Groundhog Shoot of the year, but there are several other chances for you to get out and test your skills against some of the best shooters in the region. St. Thomas Sportsmen’s Assn. has one shoot a month until October on the second Saturday of each month. Don’t think you have to be a professional shooter to come to these matches. Take it from me as I started shooting these matches about five years ago with a $270 Savage sitting on top of homemade sand bags. The guys here are great to shoot with and are always willing to help out a fellow shooter. They made me feel right at home and always helped me when I have any questions. I started doing this to become a better shooter for deer hunting. I continue to do it because I fell in love with the sport. So if you are looking for something to do on the second Saturday of the month come out and test your shooting skills and enjoy the fellowship of like-minded shooters.

DJ’s Brass Service now offers custom case hydro-forming to your exact specs. Darrell Jones offers this service for a variety of popular cartridges: 6mm Dasher, 6mm BRX, 6mm BRDX, and 6mm Shehane. After hydro-forming your brass, Darrell can also neck-up or neck-down the cases to meet your needs. For example, if you shoot a 22 Dasher, Darrell can hydro-form the cases and then neck them down to .22 caliber. He can also turn the necks to your specs (for an additional charge).
Darrell is a hydro-forming wizard who has perfected the process over the last couple of years. He has learned a few special techniques along the way to ensure uniform case-forming. Without revealing any trade secrets, we can say the Darrell has very special dies and Darrell doesn’t use a mallet or hammer — he has a system that is much more consistent. Darrell tells us: “Many of my customers take this brass and load it ‘as is’ and go straight to a match and shoot some very nice groups.”
Hydro-forming by Darrell costs $0.60 (sixty cents) per case with a minimum order of $60. Neck-turning is an additional $0.50 (fifty cents) per case plus actual return shipping. The turnaround is usually less than five days.
With Darrell’s hydro-forming service you don’t have to buy any special dies or other equipment. Darrell says: “Simply send me the brass you need or have it dropped-shipped to me along with a fired case that has not been sized. If you need formed brass for a new build (gun not yet fired), let me know and I will size the brass to fit within .001 of a PT&G GO gauge.”
For more information, visit DJsBrass.com, or call Darrell at (205) 461-4680. IMPORTANT: Contact Darrell for shipping instructions BEFORE sending brass for processing. In a hurry, don’t have time? Just call Darrell and he’ll make something work for you.
Hydro-Forming Customer Reports
Here are testimonials from recent customers.
“Recently had Darrell Jones of DJ’s Brass Service hydro-form 6 BRX brass for me. The turn around time was very fast and the brass was to the exact specification I ask for. I actually shot the hydro-formed brass in a match [without further fire-forming]. It shot a 3.597″ — pretty amazing. Let DJ do the work for you!” — Mike Wilson (3 Time IBS Record Holder; 2013 and 2014 1000-yard IBS Shooter of the Year.)
“Darrell Jones of DJ’s Brass Service went far beyond the call of duty, to assist me in preparation to shoot for my first time in an IBS match. I have had an interest in 1000-yard competition for many years and finally got the opportunity to try it. After researching the winning competitors, rifles, and rounds I ordered a Panda action with Krieger barrel in 6mm Dasher from Kelby’s. It was one week before the match and I had a rifle and no rounds. I contacted Darrell to hydraulically form 6mm dasher from Lapua 6mm BR brass. He formed the brass and had it in the mail the next day[.] Since I have only reloaded for hunting or magazine fed rifles I was not familiar with proper seating to allow land engagement of the bullets for 1000-yard accuracy. Darrell took the time to advised me every step of the way to allow me to shoot a 3.158″ (5) shot group to win my first round of my first competitive match ever.” — Mike Youngblood

Dasher Loading Tips
I use a carbide ball on the expander rod of the full length sizing die. I use a .266″ TiN-coated bushing and the ball just kisses the inside walls of the sized neck. I get very consistent neck tension this way and have had no issue with split necks.
Here’s a tip for guys who shoot the 6 PPC, 6 Dasher, 6 BRA, .284 Shehane, or other wildcat cartridges that require fire-forming. Use your fouler shots to fire-form new cases. That way your fouler shots do “double-duty” and you get your brass fire-formed without putting extra rounds through your expensive barrel.

Beneficial Aspects of Shooting

Firearms are limited to field-portable, varmint-caliber rifles in either custom or factory class, and having a maximum 6.5mm bore, but bullets must weigh no more than 107 grains. You can shoot prone or from a bench using a front rest and bag rear. For more information, visit 
Let’s start at the beginning. Before the match there is usually an opportunity to fire a few fouling shots and check sight settings for load and distance. An initial read on conditions–mostly wind direction, strength and consistency–is also made. The spotter should checklist the shooter to make sure they are set up for the relay distance and have adjusted their sights to the correct elevation and windage.
Katy and Don are avocado farmers. From time to time they’d bring a few avocados to the range to give to the other shooters. In addition, on some months, Katy would bring some home-made Guacamole made from the avocados on their ranch. Katy says “Fellow shooters appreciate a batch of guacamole so much they bring their own chips to go with the dip. I keep getting suggestions that I go into the business of making and selling guacamole. Guess I could start by selling it at the range.”
John Illum’s Rampro actions are chrome-moly steel. Commonly you’d see them blued, but I had him put a brushed nickel finish on the action and rings. From a few feet away it looks like stainless. The trigger is Illum’s own design set at 8 ounces, and there’s no creep that I can detect. The action has Remington barrel threads and will accept Remington type triggers. One neat thing is that the action was milled with an integral recoil lug (much like the current Surgeon Action). And the bolt is milled all in one piece–no soldered-on handles. My only gripe with this bolt handle is that it could be a tad longer, but it still is manageable for a single-shot. You’ll also note how slick and streamlined the scope rings are. Illum made those as well. His rings mount to the action via two screws from the inside of the ring, a very elegant set-up for sure. (I currently have a 6.5-20x40mm Nikon scope on this gun. If I had to do this project over again the only thing I would change would be installing a 30mm scope because I like ‘em!).

I think these sub-caliber rounds, both 20s and the 17s, are the future of recreational varminting, at least out to medium distances. The Twenties offer low recoil, excellent accuracy, and components keep getting better and better. The bullet-makers are finally making high-quality bullets in appropriate weights. Compared to something like a 22-250, I’ve noticed that my 20 PPC rifle has a lot less noise, a plus when you want to be quiet around other people and varmints.

St. Thomas Groundhog Shoot, Report by Jonathan Trivette
The Targets feature a groundhog with scoring rings on the left side and 5 practice rings on the right side. Shooters get as many practice shots as they want, subject to a time limit. The three relays run 6 minutes, 6 minutes and 9 minutes respectively.
