There are hundreds of cartridge types capable of winning in F-Open. For F-TR you can shoot either the .223 Rem or .308 Win, but you have many load options. This article will focus on proven choices, currently used by the top F-Class shooters in the world. Our discussion will analyze cartridge selection based on the four different F-Class sub-disciplines: Open Mid-Range, Open Long-Range, F-TR Mid-Range, and F-TR Long Range.

Mid-Range F-Open Cartridges
For starters, a .300 WSM is certainly capable of winning mid-range matches but it is not ideal. So what is ideal, and why? F-Class Mid-Range matches usually are usually shot at 300, 500, or 600 yards — or all three. At those distances the 6mm and 6.5mm cartridges rule. In moderate conditions, the 6mm Dasher is unbeatable. Its low recoil along with its super grouping ability and good ballistics make it my number one choice for Mid-Range.
Best bullets for the 6mm Dasher are: Vapor Trail 103gr, Berger 105 Hybrid, 108 BT, and 105 VLD (hunting). Best powders are: Varget, H4895, and Reloder 15.
Choices for Mid-Range in Tougher Conditions:
We all know that conditions are not always “moderate” that’s why something a little bit bigger will save you a “Nine” or two. The 6.5X47 Lapua was designed for 300-meter competition, but as soon as it was released, it was adopted by F-Class, benchrest, and tactical shooters. It offers great ballistics with very low recoil and big “accuracy window”. Lapua makes great brass for it (no surprise there) and Berger makes great bullets: 130gr VLD, 140gr VLD, 140gr Hybrids. Best powders in most barrels are Varget and H4350, I don’t use double-based powders such as Reloder 17 and the Vihtavuori N500 series because of their unpredictable performance day to day (greater temp sensitivity).
The 6.5X47 Lapua necked down to 6mm is also a great option for mid range matches. I was able to easily get 3200 fps with 105 hybrids and H4350.
Choice for Long-Range F-Open Competition
In Long-Range F-Open Class (out to 1000 yards), the big, high-BC bullets rule. If I had to pick one cartridge for F-Class (both mid- and long-range) I would pick the .284 Winchester or one of its variants. The .284 Win is currently dominating in F-Open competition. It offers great barrel life, it is super-easy to tune and its recoil is very manageable. The best bullets for it by far (in my opinion), are the Berger 180 Hybrids. But Sierra’s new 183gr MK bullet (with factory-uniformed meplats) seems to perform very well as does the Berger 180 VLD. Best powders for the .284 Win are H4350 and H4831SC.
Long-Range Only F-Open Cartridge
As much as I like the .284 Win, for long-range competitions I like the .300 WSM even more. If you look at a .300 WSM and a 6mm Dasher side by side, they appear almost identical in geometry — the .300 WSM looks like an “super-sized” Dasher. Both cartridges are currently the “darlings” of long-range benchrest due to their extraordinary grouping ability and huge “node’’ windows. Big accuracy windows allow loads to perform well in different conditions and geographical locations. That’s obviously very important if you travel to compete. The .300 WSM loaded with Berger 215gr or 230gr Hybrids is very tough to beat at long range, and it is currently my number one choice.
The 7mm RSAUM is another outstanding long-range round. It resembles a 6BR on steroids and it is almost as easy to tune. Best bullets for it are Berger 180gr Hybrids, 195gr EOLs, and Sierra’s 183gr MatchKing. Best powders for the 7mm RSAUM are: H4350, H4831SC, and VV N160.
Top Caliber/Bullet Combos for F-TR
In F-TR competition, the choice is clear — a .308 Win throated for Berger 185gr BTLRs and 200gr Hybrids will win in mid-range AND long-range comps. Many championships have been won, and many records set with those two bullets in the .308 Win. To quote Danny Biggs (a two times FTR National Champion) “The 185 BTLR is the best bullet for .308 Win ever made”.
The Berger 215gr Hybrids have been used to win many competitions including recently the 2015 F-Class Nationals. Bryan Litz won both the Mid-Range and Long-Range 2015 Championships using 215s. Bryan’s rifle is shown below:
I recommend chambers throated for the 185/200 grain projectiles over the 215/230 grain bullets. The reason is that if you have your barrel throated out for the 215s or the 230s, you could have a “slow” barrel and max out on pressure before the desired velocity is reached. Optimum freebore for the 230s is too long for the 185/200s, so you would be limited to using only 215/230gr bullets in that barrel.Furthermore, the recoil increase with heavier bullets is substantial, causing the rifle to be more difficult to shoot.
.223 Rem — Not A Competitive Option
I would stay away from the .223 Remington. On paper the 90gr VLD will shoot inside most .308 Win loads even at a 1000 yards. But in reality, on average, the .223 Rem, regardless of what powder/bullet combo is used, cannot compete with the .308 Win. [Editor: The equipment lists at major F-TR matches will confirm Kovan’s conclusion here.]
Conclusion (and Other Options)
This article covers only the (currently) most popular cartridge/bullet combos for F-Class (F-Open and F-TR). As I said in the beginning, many cartridge types are capable of winning but are not listed due to their low popularity, case design, or lack of quality components. All of the above information is based on my personal experience and it is meant to help new shooters choose the right cartridges for F-Class matches. Thanks for reading and good luck — Emil Kovan

How well can the 6mm Dasher perform at 1000 yards when conditions are good, and the shooter is riding a hot streak? Well here’s a shot-by-shot record of Scott Nix’s 4.554″ 10-shot group shot at Missoula, Montana at the Northwest 1000-yard Championship a few years back. All 10 shots were centered for a 100-6X score. That’s about as good as it gets. If Scott had stopped after 5 shots, his group would have been under 3 inches!
Video Demonstrates Amazing 1000-Yard Accuracy
Watch the video. You can see the group form up, shot by shot. It’s pretty amazing. Scott’s first shot (at the 45-second mark of the video) was right in the X-Ring, and four of Scott’s first five shots were Xs. That’s drilling them! This video was recorded from the pits at the 1000-yard line, during record fire.
Share the post "The Amazing 6mm Dasher: 10 Shots in 4.554″ at 1000 Yards"
Rodney Wagner shot the smallest 5-shot, 600-yard group in the history of competitive rifle shooting. First measured at a mere 0.349″, then certified on the IBS Record books at 0.336″, Rodney’s group is mind-blowingly small — and it was centered for a 50 score. This amazing group shows what can be done with a great gun, a talented shooter, and superb hand-loaded ammunition. Today’s Tech Tip reveals some of Rodney’s reloading methods that helped him put five shots you could cover with a dime into a target 600 yards away.
Creating Ultra-Accurate Benchrest Ammunition
Rodney takes great care in loading his brass, and he employs a few tricks to get superior consistency.
Fire-Forming — To prepare his cases for fire-forming, Rodney starts by turning his Lapua brass to just past where the new neck-shoulder junction will be: “I just cut enough for the 6mm Dasher neck. A little bit of the cut shows on the shoulder after forming.” Then Rodney runs a .25-caliber K&M mandrel through the whole neck, expanding the neck diameter. After the entire neck is expanded, Rodney re-sizes the top section with a Wilson bushing, creating a false shoulder. Then, as further insurance that the case will be held firmly in place during fire-forming, Rodney seats his bullets long — hard into the lands. When fire-forming, Rodney uses a normal 6mmBR load of 29.8 grains of Varget: “I don’t like to stress my brass before it has been hardened. I load enough powder to form the shoulder 95%. Any more than that is just wasted.” Rodney adds: “When fire-forming, I don’t want to use a super-hard primer. I prefer to use a Federal 205, CCI 200, or Winchester — something soft.” Using a softer primer lessens the likelihood that the case will drive forward when hit by the firing pin, so this helps achieve more consistent “blow lengths”.
Ammo Loading — Rodney is fastidious with his brass and weighs his charges very precisely. Charges are first dispensed with an RFD manual powder measure, then Rodney trickles kernel by kernel using a highly-precise Sartorius GD-503 laboratory scale. He tries to maintain charge-weight consistency within half a tenth of a grain — about two kernels of Varget powder.
One important technique Rodney employs is sorting by bullet-seating force. Rodney batch-sorts his loaded rounds based on seating force indicated by the dial gauge on his K&M arbor press: “I use a K&M arbor press with dial indicator strain gauge. When I’m loading I pay lots of attention to seating effort and I try to batch five rounds that feel the same. For record rounds I try to make sure I get five of the same number (on the dial). When sorting based on the force-gauge readout, you need to go slow. If you go too fast the needle will spike up and down before you can see it.”
In practice, Rodney might select five rounds with a gauge value of 25, then another five with a gauge read-out of 30 and so on. He places the first five like-value rounds in one row of his ammo caddy. The next like-value set of five will go in the next row down. By this method, he ensures that all five cartridges in a five-round set for a record target will have bullets seated with very consistent seating force.
Unlike some top shooters, Rodney does not regularly anneal his cases. However, after every firing, he does tumble his Dasher brass in treated corncob media. After sizing his brass, before seating the bullets, he runs a nylon brush in the necks: “The last thing I do before firing is run a well-worn 30 caliber nylon brush in the necks, using a small 6-volt drill for power. This is a quick operation — just in and out the neck”. Sometimes, at the end of the season, he will anneal, but Rodney adds: “If I can get 10 firings out of the case I’ve done good.” He usually makes up new brass when he fits a new barrel: “If it is a good barrel (that I may shoot at the Nationals), I’ll usually go ahead and prepare 200 pieces of good brass.”
Tips for 600-Yard Shooters New to the Game
In the course of our interview with Rodney, we asked if he had any tips for shooters who are getting started in the 600-yard Benchrest Game. Rodney offered some sensible advice:
1. Don’t try to go it alone. Find an old-timer to mentor you. As a novice, go to matches, watch and ask questions.
2. Go with a proven cartridge. If you are shooting 600 yards stick with a 6mmBR or one of the 6BR improveds (BRX or Dasher). Keep it simple. I tried some of the larger cartridges, the 6XC and 6-6.5×47 Lapua. I was trying to be different, but I was not successful. It wasn’t a disaster — I learned something. But I found the larger cases were not as accurate as a 6BR or Dasher. Those bigger cartridges are competitive for score but not for group.
3. You don’t have to spend a fortune to be competitive. Buy a used rifle from somebody and find out if you like the sport. You can save a lot with a used rifle, but do plan on buying a new barrel immediately.
4. Don’t waste weeks or months struggling with a barrel that isn’t shooting. My best barrels, including this record-setting Brux, started shooting exceptionally well right from the start.
Rodney’s record group was measured at 0.349″ at the match, then IBS record-certified at 0.336″.

IBS Match Report by Tom Jacobs and Jim Bauer
“What a wonderful match” — those words were heard often during this year’s IBS 600-yard National Championship match. Tom and Sara Jacobs hosted the 600-yard Nationals September 26-27 at their Vapor Trail Valley Range in Spickard, Missouri. Attendance was strong, with 78 competitors from 14 different states. The Vapor Trail Valley range holds both 600-yard and 1000-yard yard matches throughout the year. Located in northwest Missouri, Vapor Trail Valley sits in the middle of crop ground and cattle country. The terrain is a mixture of tree lines and green pastures.
It seemed every aspect of the match came off flawlessly, thanks to the hard work of the organizers. Even the weather cooperated, with 80 degree days and 60 degree mornings. The wind was mild but twitchy, providing a challenge for the competitors. Overall though, conditions were generally good and some very impressive results were recorded. Despite the twitchy winds, over the course of the weekend, some eighty perfect 50-point targets were shot. That’s darn good shooting overall.
Interesting Factoids from Vapor Trail:
1. Competition is VERY tight now. The difference between 1st place and 20th place in Light Gun Group Aggregate was .478″, less than half an inch. The difference between 1st and 20th place in Heavy Gun Group aggregate was .480″, again less than half an inch.
2. 6mm cartridges, particularly the 6mmBR and Dasher, now dominate the 600-yard Benchrest game.
All but one Light Gun was chambered as a 6mm, mostly 6BRs or Dashers. Even in the Heavy Gun division, 6mms ruled — 58 out of 61 Heavy Guns were chambered for 6mm cartridges, mostly Dashers.
3. These rigs are capable of extreme accuracy. The ten best Light Gun groups were all under 1.250″ (FYI, at 600 yards, one-quarter-MOA is 1.570″). And, as you can see at right, the three smallest Light Gun Groups were all under 0.9″. Think about that — a one-inch group used to be considered darn good at 300 yards.
This photo shows the winners in the front row, kneeling. Left to right are: Bud Larson (HG Score), Richard Schatz (2 Gun Overall, HG Group) , and Jim Bauer (HG Overall).
After Friday practice, the match began with the Light Gun relays on Saturday. Both Light and Heavy Guns shoot 8-target Aggregates. At the end of the day Saturday, Tim Gonnerman was the Light Gun Group winner with a 2.236 Agg , edging runner-up Jason Walker by a mere .003″. That’s about as close as it gets. Dan Hullinger won Light Gun Score with a 382 (Danny Wake also had a 382 but placed second on the tie-breaker). Richard Schatz, “Mr. Consistent”, placed 4th for score and 5th for group to take the Light Gun Overall title. Last year’s two gun Champion Ryan Hunt finished in second place.
Equipment Choices of Two Gun Top 20
If you review the equipment list for the Top 20 Two Gun competitors, you’ll find that Nightforce scopes were used by 19 shooters, while BAT actions were used by 15 shooters. Remarkably, 17 out of the top 20 used rifles chambered in 6 Dasher. Hodgdon Varget was the most commonly-used powder followed by Alliant Reloder 15. In the barrel department, Brux enjoyed a slight edge over Krieger, with ten shooters using Brux Barrels vs. seven using Kriegers.
Note the large, extended-width base-plate under the forearm. This spreads the load and provides more stability when used with super-wide SEB MAX front rest.
The Heavy Guns came out on Sunday. Early morning relays saw a dead-flat wind condition that constantly changed as the day progressed. Scores settled a little and groups opened up, creating a little room between competitors. In the end, Bud Larson won the Heavy Gun Score title with a 385 total. This year’s Shooter of the Year leader Andy Ferguson was close behind with a 384. The Heavy Gun group champion is Richard Schatz with a 2.003 Agg, followed by Jim Bauer with a 2.017. The Heavy Gun overall went to Jim Bauer followed by “Andy Who?” Ferguson (see photo below).
The 2015 IBS 600-yard Two Gun Champion is Richard Schatz with 18 rank points. If you look at the new 600-yard traveling trophies, you’ll see Mr. Schatz’s name multiple times — this victory marks the third time Richard has won the 600-yard, Two Gun IBS National Championship in the past decade. Richard Schatz is certainly a great ambassador for our sport and a true gentleman. Second Place in the Two Gun overall went to Jim Bauer, not far behind with 20 rank points. Taking third was Andy Ferguson with 28 rank points.
Left to right are Two Gun Overall winner Richard Schatz, along with top female Shooter, Sally Bauer and Tom Jacobs, Vapor Trail Valley range owner.
The top lady shooter was Sally Bauer. A past IBS 1000-yard Shooter of the Year, Sally is a 7-time female National Champion in 600-yard or 1000-yard benchrest. Rory Jacobs was the Junior “Top Gun” this year, winning the Junior division and finishing 10th Overall among ALL shooters (of any age) in the Two-Gun Agg. Rory is a four-time Junior National Champion and three-time Junior shooter of the year. The top Rookie shooter was Carroll Lance.
As with many of the matches that we attend, the range owner’s family and friends make up the help for scoring and target crews, the lunch attendants and general maintenance of the ongoing match. This match is no different. Tom and Sara’s families took care of all the required chores and it all came together like a well-oiled machine. Give credit to Tom Jacobs for working with the sponsors to put together a great prize table — every shooter in attendance got a sponsored prize. Please take the time to let our sponsors know that you appreciate their generous support.
There was an excellent prize table, as this young fellow demonstrates
“Andy Who?” — Ferguson is Front-Runner in 600-Yard Shooter of the Year Race
Here’s the “Andy Who?” story. Andy Ferguson, a good friend and neighbor of the Vapor Trail Valley range owners, is currently leading the 600-yard Shooter of the Year (SOY) point competition. Given his hot shooting and top ranking in the SOY chase, some of Andy’s friends/fellow competitors thought Andy might be getting a “big head” (i.e. oversize ego). To bring him down to earth, as a joke, Andy’s friends printed up the “Andy Who?” T shirts. A good laugh was had by all.

With all the talk about the new Norma Dasher brass coming in the fall from Bullets.com, we thought it was time to feature 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 ugraded 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 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.

Forum Member Chuck L. (aka “Ridgeway”) has created a handsome duo of 6mm Dashers for competitive benchrest and varmint matches in Pennsylvania. Both guns are built on Kelbly Panda RBLP actions, with Bartlein 8-twist barrels, and Shehane Laminated Tracker Stocks. However, the two rifles are not exact twins, as you can see. One, which we’ll call the Big Dasher, is built on a Shehane ST1000 Tracker stock. The other gun, the Small Dasher, sports Shehane’s “Baby Tracker” stock — a design used with great success by Richard Schatz. The Big Dasher, optimized for 1000-yard competition, also has a slightly longer freebore — 0.136″ vs. 0.104″ for the Small Dasher.
Chuck tells us: “I don’t get out shooting competition as much as I want due to time and family, but when I do compete, I shoot a Groundhog match at Southfork Rifle Club in Beaverdale, PA. Info on Southfork Club events can be found at Southforkrifleclub.com. The Southfork match is basically a 100-, 300- and 500-yard match with one sighter the entire match and 5 shots at each yardage for score. The Small Dasher, with the shorter ‘Baby Tracker’ stock, was set up for the Southfork Rifle Club’s ‘Light Unlimited’ class which has a 13.5-lb max weight.” (Editor: ‘unlimited’ is a misnomer for a weight-limited category.)
Chuck adds: “The Big Dasher with the heavy ST-1000 stock is set up for 1000-yard benchrest matches in Light Gun class. I hope to shoot a couple 1K matches with it at Reade Range in southwest Pennsylvania. I am still in load development for this rifle since it was just finished in January. One ironic thing is, it shoots the same load I’m shooting out of the lighter gun rather well. The only difference between the two chambers is the freebore is roughly thirty thousandths longer on the 1K gun (Large Dasher). I will also shoot this at Southfork in the ‘Heavy Unlimited’ class.”
Specifications for the Dasher Duo:
Small Dasher (13.5-pounder): Chambered for 6mm Dasher with approximately .104 freebore and a .264 NK. (No way of knowing exactly since it freebore was done in a separate operation by Kelbly.) Components are: Shehane Baby Tracker stock, Kelbly Panda RPLB action, Bartlein 1:8″ LV barrel at 26 ¾”, Kelbly Rings, Weaver T36, Jewell trigger. The barrel was chambered by Kelblys and the stock was bedded, glued and balanced by a shooting buddy (Forum Member johara1). I clear-coated the stock with auto urethane. Total weight is 13 lbs., 4 ounces.
Big Dasher (1K Light Gun, 17-pounder): Chambered for 6mm Dasher with a .136 freebore and .264 neck (PTG Reamer). Components are: Shehane ST-1000 stock, Kelbly Panda RPLB action, Bartlein 1:8″ HV 5R barrel at 28″, Shehane +20-MOA rings, Nightforce NXS 12-42x56mm, Jewell trigger. The barrel work, pillar installation, and bedding was done by Dave Bruno. The stock was clear-coated by Chuck with auto urethane. Chuck also made the rear butt plate and balanced the rifle. Total weight: 16 lbs., 13 ounces.
Dasher Case-Forming: Neck-Turn then Fire-form with Bullets Hard in Lands
To fireform, I turn my cases down to fit the chamber and stop where the false shoulder makes snug contact with the chamber. Fire-forming rounds are loaded up with a 29-grain charge of H4895 or Varget and a 108gr Berger bullet seated hard into the lands about 0.020″ past initial contact with the rifling. It takes about three firings to make a nice clean Dasher case with a sharp shoulder. I anneal about every 3-4 firings. I have many cases that have about 10+ firings on them and they are still shooting well. The primer pockets are a little looser, but still hold a primer.
Both Dashers Group in the Ones at 100 Yards
My main bullet for both rifles is the 107gr Sierra MK, loaded with Reloder 15 powder, Lapua cases and CCI 450 primers. My main load for the Small Dasher is 33.0 grains of Reloder 15. This load shoots in the ones at 100 yards. For the Big Dasher, I’m still working on a load, although the same 33.0 grain load shoots in the ones in the heavier gun as well. I’m still looking for more velocity and my ‘max’ node. So far, I’ve gone well above 33.0 grains of RL 15 without pressure signs, but that load produces vertical at 100 yards, so I’m going to tinker with the load until I see pressure or it starts to shoot.

Richard Schatz, the “Duke of Dashers”, has done it again. Just look at that group! Believe it or not, that is five shots at 600 yards. There are four shots in one ragged hole, with one a bit to the right. The group, initially measured at between 0.402″ and 0.410″, is very close to an IBS World Record. Assuming (on the high side) that that group measures 0.410″, that works out to 0.065 MOA. Wow.
Schatz, a past IBS 600-yard National Champion, shot this group in a Heavy Gun relay on May 18, 2014 at the Columbus Sportsman’s Association range in Columbus, Wisconsin. Richard was using his trusty 6mm Dasher, a 17-lb Light Gun that he has been shooting for years. His ultra-accurate load consisted of 103gr Spencer Bullets pushed by Varget and CCI 450 primers. The Lapua brass had recently been annealed and he batched his record rounds “by feel” based on the force needed to seat the bullets.
Richard said the group involved a good bit of luck, and perfect timing. The conditions were generally “switchy and difficult” at the match. However, in one Heavy Gun relay, Richard said “the wind flags just dropped straight down at the end of the sighter period. It’s like the range went dead.” Richard had windage on his scope so he just held off to correct for the calm. “I didn’t guess the hold-off correctly”, Richard admitted, “that’s why the shots ended up at the edge of the 9 Ring.”
Twenty Seconds of Near-Perfect Shooting
Richard got his five record rounds down range in about 20 seconds. He can shoot faster but, given the exceptional conditions, he took a little more time to aim: “Because the flags dropped and conditions stayed calm, I slowed down a little. I made more of a deliberate attempt to shoot a small group — a conscious effort to aim more precisely. Normally I’ll try to shoot the quickest I can get the dot close to the center of the X. I was trying to be a little more precise this time.”
Whatever Richard did, it sure worked. That’s a spectacular group — one of the smallest ever shot at 600 yards. Richard, a modest guy, credited the group to good conditions, and good luck: “Like I always say ‘the wind can blow ‘em in just as easy as it blows ‘em out’.” Richard says this rifle, with the current Krieger barrel, can typically put five shots in about two inches at 600 yards, in calm, stable conditions.
Very Close to an IBS Heavy Gun Record
The current IBS 600-yard, five-shot Heavy Gun group record is 0.404″, set by John Lewis in 2008. This recent group by Richard Schatz is very, very close to that mark. At Columbus, Wisconsin, four different measurers examined Richard’s group on May 18th. The four measurements were: 0.402″, 0.403″, 0.410″, and 0.409″ (see photo). Whether or not this is a new record will be determined by the IBS official measurement committee to which the target is being submitted. It’s worth mentioning that Richard Schatz currently holds the IBS 600-yard Heavy Gun score record, with a value of 50 points (and 0.634″ tie-breaker).

In most of the country “March Madness” is all about hoops. But in the Sacramento (CA) area, “March Madness” is a popular multi-match shootfest that brings out some of the top F-Class and sling shooters in the region. During this year’s Folsom Shooting Club March Madness series, Forum member Bob A. (aka “Killshot”) brought out his “Forum Classifieds Special” and beat all comers in the F-Class Division in both the American-Canadian Match and the Long Range Regional Match (See Results). 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 Forum Classifieds, set a Sacramento F-Class range record of 200-17X. 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’m a newcomer to F-Class competition and shot my first match in 2010. After getting accustomed to the match format and seeing what others were using, 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 ugraded 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. He is an outstanding shooter himself and developed his lathe skills from several “name smiths” I won’t mention here, all while he continued in his previous profession. Marc went into building custom rifles full-time a couple of years ago and is at the point in his career that word of his work has spread. He was recently selected by Frank Galli to create 25 rifles, each customized to the buyer’s specs, for the Sniper’s Hide 2013 Group Build. Marc has also built a number of tactical-style rifles for the Northern California Practical Precision Rifle Club’s shooters, several of whom have won or placed high in major matches.
After his great shooting in March, Bob reports: “I could not be happier with my little budget build. With a few more good scores I might even stop looking at BAT Machine’s website — my little old Remington action seems able to hold its own with the BATs and Kelblys just fine.
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. Kenny’s work with an airbrush floored me, he does everything from stocks to mailboxes to gas tanks equally well.
“I use a Nightforce Benchrest 12-42x56mm with a NP-2DD reticle. To help my aging eyes I use a 3.5X BulzEyePro lens booster, I found it helped with mirage and target clarity enough that I rarely dial down the magnification even when mirage is bad.”
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 is 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.
Like many others, I settled on the high-node dose of Reloder 15. Shooting F-Class puts a good number of rounds down the tube in a short time-frame. That can be hard on throats. At roughly the 1,200-round mark the groups started to grow as the throat wore. So, a barrel set-back was needed. The barrel was rechambered by another great California gunsmith, Ken Breda (831-334-2386, Aptos, CA). Ken, a sling shooter and all-around good guy, was able to get me back shooting with little down-time. When I went back to the range, I found the now 1.25″-shorter barrel shot equally well, even with the same load I had previously used.
An October Surprise — New Range Record, 200-17X
The chamber setback and muzzle cleanup brought the Dasher back to life and it was was really shooting well with several “cleans” shot at a few distances at club matches this summer. I shot the Folsom Shooting Club’s October match, this one a 3×600. I drew relay number two and settled in to spot and score for the shooter who drew relay one. The wind was very light and good scores were being posted. I set up for my first string and fired four sighters: three 10s and one X.
“Here we go”, I thought as I went for record. Happily, the first six shots found the X-Ring before a 10 came up out of the pits. The next six shots also found the X-Ring, then another 10 came up. Shots 15 thru 19 were all Xs and I finished the string of twenty shots with a final 10. I’d cleaned the 600-yard F-Class target with 17 Xs! This was by far my best “clean” at any distance.
I followed the first string up with a 199-6X and a 195-7X as the wind was beginning to harrass everyone on their third strings. My final score of 594-30X gave me my first win in F-Open by one point. I was very happy and received many congratulations from fellow shooters after the match. It wasn’t until I arrived at the range for November’s match that I learned that my 200-17X was a new range F-Class record.
I couldn’t believe it. Considering the quality of shooters and the number of big matches held at Sacramento Valley, setting a range record of ANY type there is an accomplishment. I have been fortunate to meet and shoot with some absolutely fantastic people at the Sacramento Valley Shooting Center. It took a little while to find out just how talented some of them were — several are national champions and record-holders but you’d never know it talking to them. These guys have always been helpful to others. Likewise, I try to help out when new shooters need a hand.
Dasher Loading Tips
My chamber is set up for Lapua’s current iteration of 6mmBR brass, in the blue plastic boxes. 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 my match load, I use Alliant Reloder 15. We shoot year-’round in Northern California. It was a brisk 28º at the start of our January match this year. Your load needs to be able to carry you from that cold to the 100º+ heat we get in the summer months. While Varget is less sensitive to temperature changes, RL15 gives me lower spreads and better long range control.
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.

Last month, Sally Bauer set a pending new International Benchrest Shooters (IBS) Score Heavy Gun (HG) record for 1000-yard competition. Her score was 100-5X with a 3.495″ tie-breaker group. Sally shot the group on August 19, 2012 at the Gopher Rifle and Revolver Club in Harris, MN. If this record is approved, Sally will be the first female shooter to hold an IBS 1000-yard benchrest record. Sally’s handsome 67-lb Heavy Gun, “Stars & Stripes”, is painted with an American flag theme.
Sally Sets a Record
At the end of the Heavy Gun match #10 Sally was directed by Range Officer Gordy Mitchell to leave all of her equipment and rifle setting on her bench. Sally was perplexed by Gordy Mitchell’s direction but he assured her “It is a good thing”. Rumors swirled and Dave Holland was summoned to the pits.
Dave and Gordy brought the target back to the scoring shed and had club officials and some respected competitors measure and sign the target. All agreed Sally had just shot an IBS record score. Sally’s rifle and equipment were measured and photographed and the target sent off to the IBS for final measurement and verification.
Gun Specifications
Sally’s 67-lb Heavy Gun was originally purchased from Bill Shehane, and it uses Bill’s Maxi-Tracker stock. The gun was originally chambered for the 6-6.5×47 Lapua Improved. But the gun didn’t shoot like the Bauers wanted, so it was rechambered to 6mm Dasher by Gordy Gritters. The action is a 2″-diameter, round, chrome moly, 3-lug, 7 ½” BAT. The barrel is a 28″, 1:8″-twist Krieger, with 1.45″-diameter straight tube. The barreled action is secured in the stock with a 9″-long barrel block. The gun uses a 12X42 Nightforce BR scope and a Jewel BR trigger. Gordy Gritters smithed the rifle. Jim Sauer states: “We have known Gordy for years now and trust every phase of our gun projects — all of them are mechanical works of art. When we get our guns from Gordy we know we can put our focus on brass prep and load development and don’t have to worry about the guns being right. That really helps save time.”
Reloading Procedure for Sally’s “Stars & Stripes” Maxiby Jim Sauer
With every new rifle we start with new brass. The first step is to run them through a full length sizing die, then over an appropriate expander mandrel. Since we use a .270 neck on our 6 Dasher chambers, neck turning amounts to a 80% cleanup of the new Lapua brass necks. We do the normal primer pocket and flash-hole uniforming.
We fire-form two times to make sure we get nice sharp shoulder corners before competition. We then separate them according to weight using 1/10th of a grain differences for each box. Much of our loading process is geared around time savings. We look for easy-to-use, consistently good products and don’t vary from them unless we have a problem or results aren’t to our standards. We have chosen to shoot Clay Spencer’s 103gr 6mm bullets. We weight-sort and bearing-surface sort them and that’s it. I gave up trimming and tipping simply because it didn’t improve how Clay built them. We also use only one primer, the CCI 450.
We use one of four different powders. Our “go-to” powder is RL15, next we try Varget, then IMR 8208, and if that doesn’t work we try H4895. We have found that these bullets usually shoot best at 2970 fps. This is not an absolute, just what normally works best. We always try higher and lower velocities looking for that special load. Once we find the powder and quantity that works the best we play with the seating depth. Usually this is a fine-tune method and most of the time 15 thousandths into the rifling works the best. But don’t be afraid to jump the bullets as much as 0.100″. When we use this procedure we usually find a combination that will shoot nice, round ¾” groups at 400 yards.
Our reloading regimen starts with ultra-sonic cleaning our brass, then tumbling until shiny. We anneal the brass every time. We proceed to full-length resizing, repriming, and lubing the inside of the necks with graphite. We then charge with our selected powder and seat the bullets. We measure for concentricity, [shooting] the best ones for the record and the others for sighters. The load that Sally shot the record with is 33.0 grains of IMR 8208 XBR, CCI 450 primers, Spencer 103gr bullets, Lapua brass, bullet seated 15 thousandths into rifling, Velocity 2980 fps.
About Sally Bauer – This is the third year of competitive shooting for Sally. She listened to proper and basic instruction and learned at her pace. She developed her own style and discipline. Not wanting to be dependent on others Sally learned to set up her rests and carries Stars & Stripes to the bench by herself.
Sally and I would like to thank the kind people we have met in this crazy frustrating game of shooting. For the most part fellow competitors have been helpful and giving of the time, experience and knowledge. Every range owner and operator we have come across has treated us like family and friend. I can think of no other sport where the participants give so freely. We would also like to thank Dave Holland, Gordy Mitchell and all the others at GRRC for the professional way they handled the target and situation. — Jim and Sally Bauer
As an interesting historical note, Gordy Mitchell observed that there was an all-star line-up at the match when Sally set her record: “After checking our bench roster I noticed we had three national champions (2009-Ed Nazy, 2010-Jim Bauer, 2011-Todd Soeby) and current top five Shooter of the Year points leaders (Al Forbes, Sally Bauer, Jim Bauer, Shannon Lowman, and Larry Bryant) all at one match.”

Long-range benchrest shooter Scott Weber had a pretty decent day at the range last Saturday — to put it mildly. Shooting his 6mm Dasher in a Williamport (PA) 1000-yard match, Scott recorded two new Light Gun world records, breaking a record set by Scott’s own father (Frank Weber) in the process.
Early in the day, Scott shot a 3.746″ (99-1X) 10-shot group which beat the existing group-size record, a 3.835″ group shot at the Montana Deep Creek Range in 2006. Then, in the shoot-off, Scott drilled a 100-6X score to top the existing score record held by his father Frank Weber. Interestingly, Frank’s 2012 record was also a 100-6X, but Scott has the smaller group — 4.007″ vs. Frank’s 4.237″ — so Scott will be credited with the record. Well at least he kept it in the family!
Scott reports: “It’s unbelievable to set one record but two in one day on different relays — it doesn’t seem real. All I wanted to do was win the shoot off since I never won one since I’ve been shooting. My dad is happy for me , but he told me ‘don’t look back’ because he is coming to get his record back!”
INSIDE STORY — Rifle Specs and Load Details
Scott Tells us: “Mark King built the rifle. It is similar to my dad’s Light Gun that Mark also built. It has a Sitman (Master Class) stock with 2-inch rail in the back, BAT 3-lug action, Broughton barrel with Mark King brake, and a Jewell trigger. My scope is a Leupold 8.5-25X, MK IV.” The Broughton barrel is chambered for the 6mm Dasher with a 0.266″ neck. Scott turns his necks to about 10.5 thousandths thickness and runs 0.261″ neck tension.
Two Loads for Two Records
Scott used two different loads during the match: “The load I used for the group record was 32.7 grains Varget with CCI primers, 107gr VLD custom bullet, seated +.010 into the lands. These 107gr VLDs were experimental bullets I just recently received. I used a different load in the shoot-off when I broke the score record. That load was 33.7 grains Varget, CCI primers, 105 Berger hunting VLD, seated +.010 into lands. The Bergers were trimmed and pointed hard with a Hoover pointing die.” [Editor’s Note: The 33.7 grain load is very stout and may be UNSAFE in some Rifles. Both listed loads should only be used with fully-formed Dasher cases.]

Report by Birdog
Forum member John S. aka “Voldoc”, came over Sunday to check the elevation come-ups on his new March scope. At my home range, dubbed the ‘Dasher Dome’, we had either a gong or paper target at 100-yard intervals to 800 yards. Voldoc wanted to check his ballistic chart against real world conditions. Voldoc will use this test to verify his come-ups for a “quick-view” BDC tape that will be applied to his elevation turret. He was running his “go to”, tried and true “red mist load”, an 87gr Hornady V-Max. The rifle was a Nesika-action 6mm Dasher with 1:12″-twist HV-contour Krieger. Doc has doubles with this combination out to 700 yards and many kills past 1,000. [Editor’s Note: We featured Voldoc’s varmint rifles in our Tennessee Triple Threat story, a Gun of the Week article on this site. Notably, Voldoc made a 1,000-yard plus prarie dog kill with a 20BR shooting 55gr Bergers.]
My ‘Dasher Dome’ is a good place for testing. Dirt berms have just been completed at 100, 300, 600, 700, an 780 yards. Voldoc started at 100 and shot at 100-yard intervals recording his elevation at each interval. His ballistic chart was within a click or two at each distance. When he reached 780 yards, he repeated the test at each distance down to 300 yards. Dead on!
Custom BDC Turret Tapes
Doc already has ballistics tapes fitted to his Nightforce-equipped rigs. But Doc’s new Dasher has a March so he need to confirm the come-ups. The tapes, made by Forum member Dominic (aka “Xterminator”), show rotation clicks for various yardages. There are versions for both standard and “High-Speed” Nightforce turrets, as well as some other scope brands. For more info, send email to: media-banc [at] videotron.ca . Learn more about Dominic’s custom come-up tapes in this Forum Thread.

The photo at right confirms that VolDoc has his zeroes confirmed at 780 yards. Look closely. That’s about a 1.5″ center-mass group on ‘Chico’ the prairie dog (lower right). Nice Shooting Doc! Chico’s buddy, ‘Chuckie’ the steel ground-hog, took many hits. Show in photo are three hits in the throat zone.
Good Friends, Good Rifles Make for the Best of Times
Birdog reports: “Overall, this was a great way to spent a Sunday. Temps reached 103° F, but Doc got to the ‘Dasher Dome’ at 5:30 a.m. and we beat the heat. After testing was completed, we walked two miles with temps in the 90s. What can I say — good friends, good BRs — this was the best of times!
Serious Rangefinders:
Very high-quality laser rangefinders permitted the shooters to confirm target distances with great precision. Birdog uses a Vectronix LRF while Voldoc uses a Leica GeoVid rangefinding binoculars.

.223 Rem — Not A Competitive OptionEmil Kovan Competition History:
How well can the 6mm Dasher perform at 1000 yards when conditions are good, and the shooter is riding a hot streak? Well here’s a shot-by-shot record of Scott Nix’s 4.554″ 10-shot group shot at Missoula, Montana at the Northwest 1000-yard Championship a few years back. All 10 shots were centered for a 100-6X score. That’s about as good as it gets. If Scott had stopped after 5 shots, his group would have been under 3 inches!
One important technique Rodney employs is sorting by bullet-seating force. Rodney batch-sorts his loaded rounds based on seating force indicated by the dial gauge on his K&M arbor press: “I use a K&M arbor press with dial indicator strain gauge. When I’m loading I pay lots of attention to seating effort and I try to batch five rounds that feel the same. For record rounds I try to make sure I get five of the same number (on the dial). When sorting based on the force-gauge readout, you need to go slow. If you go too fast the needle will spike up and down before you can see it.”
All but one Light Gun was chambered as a 6mm, mostly 6BRs or Dashers. Even in the Heavy Gun division, 6mms ruled — 58 out of 61 Heavy Guns were chambered for 6mm cartridges, mostly Dashers.
Dasher Loading Tips
“Here we go”, I thought as I went for record. Happily, the first six shots found the X-Ring before a 10 came up out of the pits. The next six shots also found the X-Ring, then another 10 came up. Shots 15 thru 19 were all Xs and I finished the string of twenty shots with a final 10. I’d cleaned the 600-yard F-Class target with 17 Xs! This was by far my best “clean” at any distance.
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.
