Can you form a wildcat cartridge such as the 6 Dasher 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:
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.
This same procedure can be accomplished with a Whidden Gunworks 6mm Dasher hydraulic form die. We like the Whidden hydro-forming die for its production quality and consistent results. This Whidden system works great according to our Forum members.
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 Whidden or 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.

Bauer Power. Today’s Sunday Gunday story features Jim Bauer and Sally Bauer, a “power couple” in the International Benchrest Shooters (IBS) mid-range and long-range benchrest game. Jim and Sally both compete at 600 yards and 1000 yards, and both have been VERY successful. A decade ago, in 2012, Sally was the IBS 1000-yard Shooter of the Year. She had a great season, piloting her impressive Stars & Strips Heavy Gun (shown above). Sally now serves as the IBS Treasurer.
Jim Bauer has also been a top IBS performer shooting a similar, wide-forearm Maxi-Tracker Heavy Gun, with beautiful Eagle-on-black paint scheme. Jim Bauer won the IBS 2015 1000-Yard Nationals shooting a 6mm Dasher in both Light Gun and Heavy Gun classes. And Jim holds the IBS 1000-yard 20-Target Light Gun Aggregate Score Record. He set the record in 2021 with 47.15 Agg Score and 5.4171″ group average — that’s very close to half-MOA for 10-shot groups at 1000 yards!
Jim Bauer Wins 2015 1000-Yard Title with Duel Dashers
Jim Bauer won the IBS 2015 IBS 1000-Yard Nationals shooting a 6mm Dasher in both Light Gun and Heavy Gun Classes. Here’s his match-winning Heavy Gun. Smithed by Gordy Gritters, Bauer’s Heavy Gun featured a BAT action, Krieger barrel (in barrel block), Shehane HG stock, and Nightforce scope.
At the 2015 1000-Yard Nationals, Jim Bauer was both Two-Gun Champion and Overall winner. Bauer shot great in both Light Gun (LG) and Heavy Gun (HG) matches, posting Top 10 finishes in both classes. Bauer ran 6mm Dashers in both Divisions (LG and HG) with Vapor Trail bullets.
Sally Bauer Honored as 2012 IBS 1000-Yard Shooter of the Year
In 2012, Sally Bauer became the first (and only) lady to win the title of IBS 1000-yard Shooter of the Year. Sally earned that honor through hard work, dedication, and a burning desire to “be all she can be”. While helping her husband Jim rise to the top of the 1000-yard benchrest game, Sally was taking notes and working toward her turn at the top. Well friends, Sally took no prisoners in 2012 and earned Shooter of the Year honors. Sally’s handsome 67-lb Heavy Gun, “Stars & Stripes”, is painted with an American flag theme.
Sally Bauer and the IBS 1000-Yard Heavy Gun Record
A decade ago, in 2012 Sally Bauer set a then-pending 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. Though that record has been surpassed (with a smaller tie-breaking group), Sally was the first lady ever to post a pending IBS 1000-yard benchrest record.
Sally’s Amazing 1K Group
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.
Sally’s Heavy 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 12-42x56mm 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.”
Editor’s NOTE: The following information was for the original 2012 load Sally ran in her IBS Heavy Gun. Load details and procedures may have changed now, a decade later.
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 – In her “formative years” of competitive shooting, Sally 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.
Jim Bauer reports: “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.”

Have you tried IMR Enduron powders yet (IMR 4166, 4451, 4955, 7977, and/or 8133)? We’ve been impressed with what we’ve seen. IMR’s line of Enduron extruded powders offer excellent temp stability, reduced copper fouling, and good load density for many popular cartridges (such as .223 Rem, 6mmBR, .308 Win, .30-06, 300 WSM to name a few). Some of our Forum members have reported excellent results with IMR 4166 in the 6mmBR, Dasher, 6.5×47 Lapua and .308 Win. One member wrote: “in my 6.5×47… 4166 gives speeds and accuracy pretty much exactly the same as Varget.” And other shooters have observed reduced copper fouling with Enduron series powders, so IMR’s Enduron anti-fouling chemistry does seem to work.
IMR now offers five (5) Enduron powders: IMR 4166, IMR 4451, IMR 4955, IMR 7977, and IMR 8133. Shooters looking for good alternatives to hard-to-find extruded powders should definitely check out the Enduron line-up. Precision shooters will find an Enduron option well-suited to most popular precision cartridge types. For example, IMR 4166 is a good replacement for Hodgdon Varget (commonly used in the .223 Rem, 6mmBR and .308 Win), while IMR 4955 is a fine substitute for H4831 (favored by F-Open shooters for the .284 Win and 7mm WSM cartridges).
The Enduron Line-Up of Five Powders
IMR now offers five Enduron powders that cover a broad range of burn rates. They are suitable for a wide variety of cartridges, from small varmint cartridges all the way up to the .338 Lapua Magnum.
IMR 4166 possesses the fastest burn rate in the Enduron lineup. It is the perfect burn speed for cartridges such as .308 Win, 7.62mm NATO, 22-250 Rem and 257 Roberts. A versatile, match-grade propellant, IMR 4166 is comparable to Hodgdon® Varget.
IMR 4451 is a mid-range burn speed powder, ideally suited for cartridges such as .270 Winchester, .30-06 and 300 Winchester Short Magnum. This powder is comparable to Hodgdon H4350.
IMR 4955 is a medium burn speed powder, falling in between IMR 4451 and IMR 7977 in burn speed. It provides top performance in big game cartridges such as 25-06, 280 Remington and 300 Winchester Magnum. This powder is comparable to Hodgdon H4831.
IMR 7977 is a slower burn rate in the Enduron family. Loading density is perfect for magnums. This is a true magnum propellant yielding outstanding performance in .300 Winchester Magnum, 7mm Remington Magnum and .338 Lapua Magnum. IMR 7977 is comparable to Hodgdon H1000.
IMR 8133 IMR Enduron 8133 is the slowest burn rate in the Enduron family. Loading density is perfect for the very large magnums, including the 6.5mm and 7mm magnums. This is a true magnum propellant yielding outstanding performance in 6.5-300 Weatherby, .264 Win Mag, 28 Nosler and .300 Rem Ultra Mag, among other cartridges.
IMR Enduron Technology powders are sold in one-pound (1 lb) and eight-pound (8-lb) containers through quality retailers including Graf & Sons, Midsouth, and Powder Valley. Check frequently for current availability as these will sell out quickly after arrival. Also check your local sporting goods dealers for recent powder shipments.

You have to admire someone with serious do-it-yourself skills. Not just hammer and nail skills, but formidable design and fabrication skills. Well Forum Member Dave D. (aka “AKShooter”) has a DIY skill set that might put some trained machinists to shame. You see, “DIY Dave” crafted his own pedestal front rest from scratch, using his own design and about $100.00 in materials (not counting the Edgewood front bag). Dave estimates he put 20 hours of labor into the project, but the end result was worth it: “This Do-It-Yourself rest drives like a dream. I’ve played with the Caldwell and a Sinclair, they have nothing on this one.”
Dave tells us: “Here is my Do-It-Yourself front rest. I wanted to show other folks who are handy that a solid front rest is doable with a bit of time — and you don’t need to spend $1000.00. (You could say this is a design for shooters with more time than money.) This is for F-Class. I was originally overwhelmed by the equipment needed, so I decided to make my own rest. I didn’t have the money for a SEB or Farley Coaxial. This is what I’ll run this season (my second as an F-Class competitor).”
We asked Dave what equipment was used to make the rest. He explained: “My brother has a CNC cutter. But most water-jet outfits would do the work for $100 or less. All the plates are tapped and screwed. I found small machine screws on eBay.” Dave says there are other ways to build a front rest: “You could do the same with a welder and plate stock for base. It’s easier to do the top out of aluminum though, with all the tapping.”
Dave enjoys fabricating his own gear, but he admits the process can be time-consuming: “I’m a DIY guy. Sometimes I wrap up a project and wonder why the heck I just spent X amount of time on it.” Dave has other projects in the works: “Another option we are making for a friend is taking a cheap front rest and bolting to a 3/4″ thick, wide MDF base and adding additional adjustment screws. The hardware store is your friend!”
On the competition front, Dave is tuning up a 6mm Dasher: “My rifle last year was a .260 Rem Savage repeater. I was about middle of the pack in my group of shooters. Just went with unsorted Bergers and Lapua brass, and had a ton of fun. Now I’m in — hook, line, and sinker. I have an unfired 6 Dasher barreled action from the folks at Kelbly’s to break in. I’m cheap, so I ended up with a Do-It-Yourself stock for the Dasher.” Hopefully Dave will send us a photo of his DIY-stocked Dasher when the gun is dialed-in and “ready to rumble”.

How well can the little 6mm Dasher perform at 1000 yards when the 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″ ten-shot group shot at the Deep Creek Range outside 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 three 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.
Deep Creek Range
The Deep Creek Range in Missoula, MT is one of the nicest places to shoot in the Intermountain West region. The range is located in the mountains within a few minutes drive of Missoula, and there is camping on-site. When conditions are good at Deep Creek, records get broken. To learn more about shooting at Deep Creek, contact Jamey Williams at jameydan[at]gmail.com.

Pieter “Piet” Malan is a South African precision rifle shooter and hunter who has created an impressive YouTube Channel with over 300 videos. While Pieter’s Impact Shooting Channel focuses primarily on tactical PRS/NRL type disciplines, his channel also includes dozens of videos of interest to hunters and anyone who handloads rifle cartridges. We particularly like Pieter’s tech review videos which explain important reloading methods and showcase new products.
Here are five Peiter Malan tech videos. Topics include annealing, hydro-forming, case priming, MOA vs. MILs, and how to record video with spotting scopes. As a bonus for you hunters out there, we added Pieter’s recent hunting video, Kudu Hunting Paradise Part 2. After watching that, you’ll probably want to book an African Safari.
Annealing Cartridge Brass with AMP Annealer
With premium cartridge brass for popular match cartridges now approaching $1.20 (or more) per case, you want that new brass to last. But after multiple firings, even the best cartridge brass will start degrading. That’s where annealing comes in. Proper, precision annealing can restore case-neck consistency, reducing ES/SD and improving accuracy. Some top shooters anneal after every firing to keep their brass in top condition. Others will anneal after every 4-6 firings.
Today with the advanced AMP microprocessor-controlled annealing machine, brass cartridge annealing is easier yet more precise than ever. The AMP Annealer provides advanced electrical induction annealing with ultra-precise temperature control set perfectly for your cartridge type and brand of brass. In this video, Pieter shows how to use the AMP Annealer to anneal 6mm Dasher cases and other cartridge types.
Hydro-forming Dasher Brass Using Hammer Method
In this video, Pieter Malan explains the hydro-forming process for Dasher brass and shows how he does the job using the mallet method with hydro-forming dies. He shows that it takes some technique (and multiple hammer blows) to get a good result, with a case that will fit in the chamber.
Fire-forming 6mm Dasher brass can be fairly costly if you factor in barrel life along with the cost of components. If you figure a new 6mm custom barrel, chambered and fitted by a top smith, could cost $650.00 and may only be good for 1300 rounds (in competition), barrel cost per shot is $0.50 (fifty cents). Add the price of a bullet, powder, and primer, and you are approaching $1.00 per round. Given those numbers, it makes sense to hydro-form your 6mm Dasher brass. In the USA, DJ’s Brass will hydro-form and then anneal your cases for $0.60 per case. That’s not much more than the barrel cost per shot alone for fire-forming.
MOA (Minute of Angle) vs MRAD (Milliradians)
This is a good basic introduction to the two types of angular measurements used in modern optics. Benchrest and F-Class shooters tend to favor Minute of Angle (MOA) scopes. One MOA is 1.047″ at 1000 yards. Scopes may be calibrated with 1/4 MOA or 1/8 MOA click values. Tactical and military shooters tend to prefer the Milliradian (Mil or Milrad) system, normally with 1/10 Mil click values. A Milliradian is an SI-derived angular measurement — one thousandth of a radian (0.001 Radian). At 100 yards, a 0.1 Mil click is 0.36″, while a full Mil is 3.6 inches. And practically speaking, 1 Mil at 100 meters is equal to 10 centimeters. MORE INFO: MOA and Mils Explained.
Primal Rights CPS — World’s Most Expensive Priming Tool
Seating primers can be a “dark art”. Many top shooters prefer to seat “by feel” using a hand tool. Others prefer lever-equipped, bench-mounted tools that offer higher work-flow rates and less strain on the hands.
There are many bench-mounted priming options — Forster has a tool, as does RCBS, and Lee. At the top of the heap is the $600 Primal Rights Competition Primer Seater (CPS). This may be the most precise bench priming tool ever created. It is certainly the most expensive at $600.00. But the CPS delivers something special — superb, repeatable depth control, along with the ability to prime up to 1000 cases per hour. For some reloaders, that precision + productivity will justify the high price. In this video Pieter reviews his Primal Rights Competition Primer Seater.
How to Record Video Through Your Spotting Scope
There are many things viewed through a spotting scope that you might want to record for posterity — a successful hunting shot on a game animal, or steel targets being hit in a PRS match. In addition, after a match, it can be useful to study the wind conditions and mirage that occurred during a match. This can help improve your wind reading skills as you watch what unfolded.
In this video, Pieter shows how to mount a smartphone to the eyepiece of a spotting scope with a plastic adapter. This allows you to record, for posterity, what the scope is “seeing”. In addition, this allows the viewer to see the scope’s magnified image conveniently without having to strain into the eyepiece and focus on a very small exit pupil.

Can you form a wildcat cartridge such as the 6 Dasher 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:

This same procedure can be accomplished with a Whidden Gunworks 6mm Dasher hydraulic form die. We like the Whidden hydro-forming die for its production quality and consistent results. This Whidden system works great according to our Forum members.
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 Whidden or 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.

Berger-sponsored shooter Ken Sanoski claimed the top spot at the 2021 Hornady Precision Rifle Challenge (PRC) Match, winning the Open Division with the highest overall score. The 2021 Hornady PRC event was held July 9-10 outside of Evanston, WY on Hornady’s private ranch. Sanoski competed with an Exodus rifle chambered in 6mm Dasher with Berger 109gr Long Range Hybrid Target (LRHT) projectiles loaded in Lapua brass (fire-formed to 6mm Dasher).
“The Hornady PRC precision rifle series was exactly what you expect from a national-level 2-day match. Strong winds, small targets, and a stacked field of shooters”, commented Sanoski. “My Exodus Rifles in 6mm Dasher using Lapua fire-formed brass and Berger 109gr LRHTs were the winning combination to put me at the top of the leaderboard.”
Berger’s Long Range Hybrid Target projectiles feature an optimized hybrid-ogive design which easily tunes to your rifle, offers superior exterior ballistics, and high Ballistic Coefficients (BCs). Berger BCs are Doppler-verified with less than 1% BC variation. That verified BC helps make ballistic calculations ultra-precise for a high hit percentage.
6mm Dasher — A Winning Wildcat
The 6mm Dasher has long been a winning wildcat in the 600-yard and 1000-yard benchrest game. This efficient 6mmBR Improved cartridge, with a 40-degree shoulder, has also been adopted by many top PRS/NRL shooters.
The Dasher, quite simply, offers a winning combination of accuracy, low ES/SD, and moderate recoil. You can run a 105-109gr 6mm bullet at a very accurate 2950 fps node (or even higher in some barrels). And with its 40-degree shoulder, the brass is very stable. The cartridge that wins in benchrest now also wins in PRS.
The only downside to shooting a 6mmBR or 6 Dasher in PRS/NRL were issues with magazine-feeding due to the relatively short Cartridge OAL, compared to a 6mm Creedmoor or 6XC. Thankfully, that feeding issue has been solved via dedicated shorter-length actions and redesigned magazines.
As the practical/tactical game has evolved, with low recoil and high accuracy becoming ever more important, many top competitors have moved to smaller cartridges such as the 6mm Dasher and its parent, the 6mmBR Norma. These cartridges deliver outstanding accuracy plus good barrel life. However, the “short, fat” 6BR/Dasher design doesn’t feed optimally in magazines designed for the .308 Win family of cases. But now there is a turn-key solution from MDT (Modular Driven Technologies) — a magazine perfect for 6BRs and Dashers.
MDT Magazine for 6 Dasher, 6mmBR and Short Cartridges
MDT’s 6mm Dasher/BR magazine fits the parent 6mmBR cartridge and all the popular variants including the 6 BRA, 6 Dasher, and 6 BRX. MDT says this new 12-round magazine is a “one-step solution [delivering] smooth, reliable feeding for the most popular rifle cartridges in precision rifle competitions.”
MDT built this AICS-pattern mag for PRS/NRL competitors and anyone wanting to run 6mmBR-family cartridges in mag-fed actions: “The limiting factor for competitors running 6mm BR variants has been feeding. Until now, the only option has been to purchase an AICS-pattern magazine plus an additional kit to make the magazines work with the shorter cartridges. This solution costs upwards of $100 or more and can require additional tuning to work in most rifles.”
If you can’t afford MDT’s complete $89.99 6mm/Dasher AICS magazine, you can get a mag conversion kit from Primal Rights for half the price — $45.00. This is offered in 4+1 round or 10-round versions. Primal Rights states: “The 6BR AICS Magazine Conversion [delivers] reliable feeding of short standard bolt face cartridges such as the 6BR, 6.5 Grendel, 6 Dasher, and 6BRX. If you have ever tried to run a 6BR [or Dasher] out of a standard un-modified AICS magazine, you were probably met with the same disappointment the rest of us were… unreliable feeding.”
The Primal Rights 6BR AICS Mag Conversion Kit has been tested extensively with 6BR, 6.5 Grendel, 6 Dasher, and 6BRX. For these short cartridges, Primal Rights has logged “thousands of rounds of trouble-free operation” with the Mag mod kit.

Shooting Prairie Dogs at extreme long range takes some highly specialized equipment. Forum Member VolDoc and his friends have taken long-range varminting to a whole new level. With his Savage-based, Hart-barreled 20 BR, VolDoc managed a verified 1,032-yard Prairie Dog kill, possibly the longest recorded with a .20-Caliber rifle. But that’s just part of VolDoc’s impressive precision varminting arsenal. Here we showcase three of VolDoc’s accurate rigs: his stunning English Walnut Diamondback 6BR/Dasher, his Nesika-actioned “Orange Crush” Dasher, and the 1K Prairie Dog-slaying 20 BR Savage.
Diamondback Switch-Barrel Rifle Specifications
The action is a Stiller Diamondback, drop-port. The custom stock is similar to a Shehane ST-1000, but crafted from 40-year-old English Walnut. [Editor’s note: the wood on this gun is gorgeous!] There are three barrels for the gun with three different chamberings: 6BR Brux 1:8″-twist HV; 6BRX Krieger 1:8″-twist HV, and 6mm Dasher Krieger 1:8.5″ twist fluted straight contour (no taper). The scope is a Nightforce 12-42x56mm, with 2DD reticle.
Comments: This rifle is a good study in comparison of the three different chamberings. On the same rifle platform (same stock and action), each of these barrels had killed prairie dogs over 1,000 yards. So if someone asks which is best, a 6BR, or 6BRX, or 6 Dasher, VolDoc says they are all effective. The improved cartridges will deliver higher velocities, which can be an advantage. On the other hand it is simpler to load 6mmBR brass right out of the box, and it’s easy to find an accurate load for the 6mmBR (see photo).
Nesika 6mmBR/Dasher Rifle Specifications
VolDoc’s “Big Orange Crush” rifle has a stainless Nesika ‘J’ action, with 2 oz. Jewell trigger, in a painted fiberglass Shehane ST-1000 stock. Originally a 6BR, the gun is now chambered as a 6mm Dasher with a .271 no-turn neck. The barrel is a 1:12″-twist Krieger fited with Vais muzzle brake. On top is a NightForce NXS 12-42x56mm scope with double-dot reticle. The double-dot gives precise aiming and lower dot can be used as an aming point, when you need a few more MOA of elevation in the field.
Comments: Big Orange Crush shoots 87gr V-Maxs into bugholes at 3,400 fps. VolDoc’s load with the 87s is very stout, more than 32 grains of Vihtavuori N-135 with Wolf SRM primers. Cases are full-length sized, with an 0.266″ bushing for the necks.
This 3400 fps load with the 87gr V-Maxs has accounted for hundreds of Prairie Dogs killed from 97 yards to 1,050 yards. The 87gr V-Max at this speed literally picks Prairie Dogs up and throws them 10 feet vertically and laterally. VolDoc reports: “The barrel now has more than 3,000 rounds down the tube and exhibits little throat fire-cracking and no loss of accuracy. I can’t explain why, it just hasn’t deteriorated yet. This rifle is my best-ever ‘go-to’ Prairie Dog rifle.”
Savage 20 BR Rifle Specifications
The action is a Savage Dual Port, with an aftermarket Sharp Shooter Supply (SSS) 4 oz. Evolution trigger. The stock is a modified Savage factory unit that has been pillar-bedded. The factory barrel was replaced with a 28″ Hart stainless, 1:9″ twist barrel fitted with a Rayhill muzzle brake. The gun is chambered in 20 BR with a 0.235″ no-turn neck. Kevin Rayhill did the smithing. To provide enough elevation to shoot at 1,000 yards plus, Ray fitted a +20 MOA Bench Source scope base. This +20 rail is very well-crafted, and made especially for the Savage Model 12.
Comments: VolDoc reports: “When I got the Savage back from Kevin Rayhill, it still had my 6 BR factory barrel on it, as I use it to compete in Factory-class regional matches. I put on the new 20 BR Hart barrel Kevin had chambered and quickly put in a full day of load development using the 55gr Bergers (0.381 G1 BC) and the 40gr V-Maxs. Both proved very easy to tune and I soon had my loads. My 55gr Berger load with runs about 3590 fps. Varget was very accurate with the 55s (see load dev. targets below).
The mild recoil of the 20 BR, along with a very good muzzle break (Rayhill’s design) enables me to spot every hit or miss myself. Kevin also re-contoured the underside of the Savage stock so it tracks straight back on recoil, also making seeing hits easier.”
The 20 Caliber 1000-Yard Prairie Dog Quest
Making the 1032-Yard Shot with a 20 BR by Dr. John S. (aka “VolDoc”)
This article covers my recent successful quest for a 20-caliber varmint kill past 1,000 yards. This may be a first — I couldn’t find anyone else with a confirmed 20-Cal Prairie Dog kill at 1000+. I started a thread on the Varmint section of the AccurateShooter.com Forum about building a 20 BR capable of 1,000-yard Minute of Prairie Dog accuracy and many said 20 Cal bullets just could not do it. Some came to my defense and said those that doubted had never studied the ballistics of the 20BR with the new Berger 55gr bullets now available. Well, folks, I can tell you, hitting a Prairie Dog at 1000 yards isn’t easy — but it IS possible. Here’s how it was done….
Gale-Force Winds and High Temps
After arriving at our Prairie Dog Ranch in Colorado, I soon realized my quest was going to be especially difficult because we had continual 40+ mph winds and 100° heat every day. We had a special place where Birdog and I had made many 1,000-yard+ kills in years past, so I knew the ideal location but needed a small window of opportunity either early morning or late afternoon. Based on past experience, I knew I needed about 21 MOA from my 100-yard zero to get to 1,000 yards. On the first day of the Safari, I shot the 20 BR in the 45 mph brutal winds and heat of 97°. But after about 20 shots, I connected on a dog and lifted him about three feet high. Well, that’s a start.
Winds Subside — Here’s Our Chance …
On the second day of our shoot, I had listened to the early weather forecast, so I knew that there was to be a brief period of light winds early in the morning. We were out on the Colorado prairie at daylight and the conditions were perfect. The sunrise was at my back and we had about a 10 mph tailwind. I looked through my Leica Geovid Rangefinder Binos and the Prairie Dogs were out for breakfast. I quickly ranged the targets and found a group at about 1,050 yards. The technique is to find the dogs, range them, click-up according to your ballistic chart and shoot.
My first shot was very, very close. I added about four clicks up and a couple of clicks left for windage and let another go. That shot threw dirt all over, but the dog didn’t even flinch. This is another good point to remember about long-range Prairie Dog hunting. To be successful, the dogs can’t be too skittish, because if they have been shot at even a few times, they will go down and stay down. So, you should have an agreement with those in your party as to where each member is going to be shooting and respect this boundary. Drive-by shooting style is OK if that’s your thing, it’s just not mine.
Hitting the Mark — Dead Dog at 1032 Yards
On the fourth shot, I saw the dog go belly up and kick its final throws. My quest for the 20-Caliber 1,000-yard Prairie Dog had become a reality. We confirmed the distance with our lasers at 1,032 yards. Our technique for retrieving a dead dog at that range is worth mentioning. When I killed that dog, I left it in the crosshairs of my Nightforce scope. My shooting buddy kept looking through the scope (of my gun) and guided me to the deceased dog using Motorola walkie-talkies. When I got to the dog I was jubilant. I marked it with my tripod and orange jacket, and we took some pictures. (See view through scope photo below). The 55gr Bergers require a center mass hit as they will not expand, especially at that range. I centered this dog in the head — his BAD LUCK, my GOOD.
After making the 1,032-yard kill, I shot many many other Prairie Dogs with the Savage 20 BR using the 40gr V-Maxs. The dog flights were spectacular — red mist and helicopters, counter-clockwise or clockwise on demand. I killed at least five at over 500 yards. I will not use the 55 Bergers on Prairie Dogs again since the quest is over. I will use the 40gr V-Maxs and 39gr Sierra BlitzKings for next trip’s 20 BR fodder.
How well can the little 6mm Dasher perform at 1000 yards when the 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″ ten-shot group shot at the Deep Creek Range outside 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 three 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.
Deep Creek Range
The Deep Creek Range in Missoula, MT is one of the nicest places to shoot in the Intermountain West region. The range is located in the mountains within a few minutes drive of Missoula, and there is camping on-site. When conditions are good at Deep Creek, records get broken. To learn more about shooting at Deep Creek, contact Jamey Williams at jameydan[at]gmail.com.

Pieter “Piet” Malan is a South African precision rifle shooter and hunter who has created an impressive YouTube Channel with over 300 videos. While Pieter’s Impact Shooting Channel focuses primarily on tactical PRS/NRL type disciplines, his channel also includes dozens of videos of interest to hunters and anyone who handloads rifle cartridges. We particularly like Pieter’s tech review videos which explain important reloading methods and showcase new products.
Here are four Peiter Malan tech videos. Topics include annealing, hydro-forming, case priming, and how to record video with spotting scopes. As a bonus for you hunters out there, we added Pieter’s latest hunting video, Kudu Hunting Paradise Part 2. After watching that, you’ll probably want to book an African Safari.
Hydro-forming Dasher Brass Using Hammer Method
Fire-forming 6mm Dasher brass can be fairly costly if you factor in barrel life along with the cost of components. If you figure a new 6mm custom barrel, chambered and fitted by a top smith, could cost $650.00 and may only be good for 1300 rounds (in competition), barrel cost per shot is $0.50 (fifty cents). Add the price of a bullet, powder, and primer, and you are approaching $1.00 per round. Given those numbers, it makes sense to hydro-form your 6mm Dasher brass. In the USA, DJ’s Brass will hydro-form and then anneal your cases for $0.60 per case. That’s not much more than the barrel cost per shot alone for fire-forming.
In this video, Pieter Malan explains the hydro-forming process for Dasher brass and shows how he does the job using the mallet method with hydro-forming dies. He shows that it takes some technique (and multiple hammer blows) to get a good result, with a case that will fit in the chamber.
Annealing Cartridge Brass with AMP Annealer
With premium cartridge brass for popular match cartridges now approaching $1.20 (or more) per case, you want that new brass to last. But after multiple firings, even the best cartridge brass will start degrading. That’s where annealing comes in. Proper, precision annealing can restore case-neck consistency, reducing ES/SD and improving accuracy. Some top shooters anneal after every firing to keep their brass in top condition. Others will anneal after every 4-6 firings.
Today with the advanced AMP microprocessor-controlled annealing machine, brass cartridge annealing is easier yet more precise than ever. The AMP Annealer provides advanced electrical induction annealing with ultra-precise temperature control set perfectly for your cartridge type and brand of brass. In this video, Pieter shows how to use the AMP Annealer to anneal 6mm Dasher cases and other cartridge types.
Primal Rights CPS — World’s Most Expensive Priming Tool
Seating primers can be a “dark art”. Many top shooters prefer to seat “by feel” using a hand tool. Others prefer lever-equipped, bench-mounted tools that offer higher work-flow rates and less strain on the hands.
There are many bench-mounted priming options — Forster has a tool, as does RCBS, and Lee. At the top of the heap is the $600 Primal Rights Competition Primer Seater (CPS). This may be the most precise bench priming tool ever created. It is certainly the most expensive at $600.00. But the CPS delivers something special — superb, repeatable depth control, along with the ability to prime up to 1000 cases per hour. For some reloaders, that precision + productivity will justify the high price. In this video Pieter reviews his Primal Rights Competition Primer Seater.
How to Record Video Through Your Spotting Scope
There are many things viewed through a spotting scope that you might want to record for posterity — a successful hunting shot on a game animal, or steel targets being hit in a PRS match. In addition, after a match, it can be useful to study the wind conditions and mirage that occurred during a match. This can help improve your wind reading skills as you watch what unfolded.
In this video, Pieter shows how to mount a smartphone to the eyepiece of a spotting scope with a plastic adapter. This allows you to record, for posterity, what the scope is “seeing”. In addition, this allows the viewer to see the scope’s magnified image conveniently without having to strain into the eyepiece and focus on a very small exit pupil.

The 6mm Dasher wildcat cartridge is very popular among competitive benchrest shooters, varminters, and even PRS competitors. So this Sunday we thought we’d showcase a matched Duo of Dasher rifles belonging to a Forum member Chuck L. (aka “Ridgeway”). The 6mm Dasher began as a wildcat improved version of the 6mmBR Norma cartridge. The Dasher has been very successful in competition, and now factory Peterson 6mm Dasher brass is sold by Grafs.com. (But out of stock currently.)
Chuck has a prize pair of 6mm Dashers for competitive benchrest and varmint matches in Pennsylvania. Both guns feature Kelbly Panda RBLP actions, 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, has a slightly longer freebore — 0.136″ vs. 0.104″ for the Small Dasher.
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 its freebore was set in a separate operation by Kelbly.) Components are: Shehane Baby Tracker laminated 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). Chuck 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 laminated 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.
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 shoot 1K matches with it at Reade Range in southwest Pennsylvania. 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.”
Both Dashers Group in the Ones at 100 Yards
Chuck favors 107gr Sierra MK bullets in both Dashers. Other components are: Reloder 15 powder, Lapua cases, and CCI 450 primers. His 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 Chuck reported: “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.”
Dasher Brass — Three Options
1. Buy Peterson 6mm Dasher Brass
In years past, you had to create your own Dasher brass, by fire-forming (with or without projectiles), or by hydro-forming. However, Peterson Cartridge recently introduced factory-made 6mm Dasher brass.
If you do not want to waste time with fire-forming or hydro-forming, you can look for Peterson 6mm Dasher brass. This is excellent quality brass that has earned stellar reviews from purchasers. The price — $56.99 for 50 cases at Graf’s (i.e. $1.14 per case) — is nearly the same as what you’d pay for Lapua 6mmBR brass, which is $116.99 for 100 cases or $1.17 per case. The advantage is that you save time, barrel life, and you won’t lose any cases to split necks. Peterson brass can be ordered from Grafs.com. Graf’s is currently out of stock, but they should have more in a few weeks.
2. Fire-Form Dasher Brass with Bullets Hard in Lands
Chuck fireforms his Dasher brass for both rifles. Because he has a tighter-neck chamber, he neck-turns the brass first: “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.”
Chuck anneals his Dasher brass regularly to help maintain consistency: “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.”
3. Have Darrell Jones Hydro-Form Your 6BR Brass to 6mm Dasher
DJ’s Brass can hydro-form a wide variety of cases for a modest fee
Fire-forming all your own 6mm Dasher brass takes time, costs money (in bullets and powder), and consumes precious barrel life. Well there IS a better solution — you can have your new brass hydro-formed by DJ’s Brass to your exact specifications for a $60.00 per hundred, which includes annealing.
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: 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. He can also turn the necks to your specs for an additional $0.60 per case.

Outstanding New Powder from Alliant — Reloder TS 15.5 New Product Review by DasherDude
Alliant has devloped a new temperature-stable powder for long range applications. According to Alliant, this is a “slower burning version of the popular RL 15 with TZ technology” and brings some significant advantages over RL 15 and powders in the similar burn rate range (like Varget). The powder is named “Reloder TS 15.5″ (RL TS 15.5) and is created using the same TZ technology used in Reloder 16 (RL 16) and Reloder 23 (RL 23) whereby it manipulates the response of the propellant and resists the natural tendency to generate more pressure at higher temperatures and less pressure at lower temperatures. That makes RL TS 15.5 extremely stable across the full temperature range a shooter may encounter.
When Can You Get This New Alliant RL TS 15.5 Powder?
Alliant tells us that new RL TS 15.5 should start arriving on dealer’s shelves by the end of the month. Officially: “We will be putting it into distribution probably in April 2021 sometime”. Remember you heard about this powder here first.
The burn rate of RL TS 15.5 lies between RL 15 and RL 16 making it ideal for loading heavier bullets in .308 Win, 6.5 Creedmoor, 6mm Creedmoor, .223 Rem, and 6mm wildcats such as the 6mm Dasher or 6 BRA (BR Ackley). Being a bit slower than RL 15, new TS 15.5 offers higher velocities for the same charge weight as well as ability to load heavier charges for additional velocity without generating excessive pressure.
Testing Reloder TS 15.5 in 6 Dasher and .308 Winchester
I got a chance to test a pre-production powder sample of RL TS15.5 from Alliant. In my own tests with my 6mm Dasher and .308 Win, I extensively compared it with Varget that I normally use in these cartridges. In both cases, the results were nothing short of spectacular.
Powder Characteristics and Metering
This is an extruded powder and looks and feels similar to RL 16. The kernels are about 0.03 – 0.04 grains each (with the resolution of A&D FX 120i scale). RL TS 15.5 meters very well, although I had to slightly adjust the AutoTrickler to get it to meter perfectly.
As I found, later in the testing, that the powder compresses before it can generate excessive pressure in the Dasher, a drop tube helps to fill the case more efficiently if higher charges and velocities are desired.
6mm Dasher Test Rifle and Load
For testing I used my 6mm Dasher benchrest match rifle. This has a BAT 3L action, 28″ Krieger barrel, and McMillan stock. I use Lapua brass with CCI 450 primers to propel Berger 105gr Hybrids and this combination shoots quite well.
Test Firearm: 6mm Dasher, Bat 3L, 28″ 6mm HV Krieger Barrel, McMillan Stock.
Components: Lapua fire-formed brass, CCI 450 primers, Berger 105 grain Hybrid
Powder: Alliant Reloder TS 15.5
Load Testing and Velocities
Test in 6mm Dasher — Excellent Velocity, Low ES/SD
The testing comprised of shooting groups at 100 yards with increasing powder charges (OCW method) and then selecting a node. That node was found at 33.4 grains. The accuracy was excellent with remarkably low Extreme Spread and Standard Deviation (ES/SD)
My usual load is 32.9 grains of Hodgdon Varget which runs 2925 fps with an ES of around 12 fps and SD around 5 fps. For comparison, 32.9 grains of RL TS 15.5 delivered a velocity of 3022 fps. That is 97 fps greater than Varget for the same load weight (of RL TS15.5).
When used in the 6 Dasher, RL TS 15.5 had ES of 13 for 28 Shots — Remarkable!
More Velocity Plus Consistent ES/SD With the Dasher since the new node (the sweet spot) was found at 33.4 grains, that resulted in a velocity of 3050 fps (a 125 fps velocity increase) from the same rifle setup. Not only did the velocity increase, but the SD was lowered to 3.6 with an ES of 13 (calculated over 28 shots). You read that right… 13 fps ES over 28 shots!
At 34 grains without any drop tube, the load was compressed. However, there were no pressure signs. That indicates that the 6 Dasher cartridge can be loaded with a higher charge, if a drop tube was used.
.308 Winchester Velocity Results
Similar results (velocity gains) were obtained from my .308 Win with Berger 200.20X bullets. For the same charge of 44.2 grains, I recorded about 100 fps higher velocity with RL TS 15.5, compared to Varget.
Accuracy Results at 100 and 300 Yards — Very Impressive
How does RL TS 15.5 shoot on paper? Very well indeed.
6mm Dasher Load Testing with Various RL TS 15.5 Charge Weights
The groups on paper told similar stories. For the OCW method, I shot groups of increasing charges at 100 yards and then selected 33.4 grains as the optimum charge (incidentally, it was one ragged hole).
While testing at 300 yards, the conditions were very windy but since I was testing for vertical, the point of aim was kept the same for every shot. No attempt was made to correct for wind, so the groups spread horizontally (15 mph, 3 o’clock wind) but the vertical spread of all the groups was under 0.3 MOA. That gives me great hopes for the long-range capabilities of the powder.
Thoughts and Conclusions
For the past year, Alliant powders have been a welcome surprise for this tester and they have found a home in my reloading room. I struggled to find a load for my .284 Win with H4831sc and H4350 before trying out Reloder 16 and voila, it was perfect.
I have used Hodgdon Varget powder for a long time in both my 6mm Dasher and my .308 Winchester. With the .308 Win I’ve used various bullets from 168 to 200 grains. Varget has served me well. I do always need to keep the powder charge in check and so the velocities are held back a bit. Now RL TS 15.5 looks like a very impressive competitor to Varget.
With Reloder TS 15.5, Alliant seems to have delivered a harmonious mix of great accuracy, higher velocities, and lower SDs without creating excessive pressure. All of this is delivered with a very temperature-stable package. The higher velocities may allow some shooters to hit a new, better-performing node. These qualities are highly sought after by long range shooters. Accordingly, I have no qualms in saying that Alliant has created a winner here.
Alliant Official Load Data for Reloder TS 15.5
Along with the cartridge types shown below, Alliant has also released load data for .30-06 Springfield, 7x57mm Mauser, .270 Win, .260 Rem, 6.5 Grendel, .257 Roberts, 22-250 Rem, and 224 Valkyrie. CLICK for all data (larger format).
Spring is coming soon, and that means it’s time to get ready for early varmint season. Here are eight great rifles from our Shooters’ Forum Favorite Varmint Rifles Thread. You’ll see a variety of action types and stock designs, both custom and factory. And we’ve featured a wide range of chamberings, from 17 Fireball up to a .243 Super Rock Chucker (aka 6mm-06). The common factor is serious accuracy. All these rigs are great shooters that have brought smiles to their owners while bringing doom to varmints.
1. Rem 700 in 20-222 — with Birthday Gift Barrel from Dad
This is proof that you don’t have to spend a fortune to have a great varmint rig. Forum member JDS Holler posted: “Here’s my baby, ‘Plain Jane’. I took a $500 birthday check that my Dad gave me, and ordered a great barrel from PacNor, chambered in 20-222. I got busted up in a fall, and had four months down time to accumulate the components to add to my old .222 Rem 700 donor action. I couldn’t be happier with the outcome. That old Bushnell has been replaced by a Vortex Viper, and this rifle just flat shoots.”
2. 6 BRA with Krieger Barrel from Alex Wheeler
Alex Wheeler of Wheeler Accuracy knows a thing or two about accurate rifles, having built many match-winning benchrest rifles. For varmint work he likes the 6 BRA (BR Ackley) wildcat cartridge: “My favorite varmint setup is this 6mm rifle with BAT SV action in a Nesika bay varmint stock with a 1:8″-twist Krieger HV contour barrel chambered for 6 BRA. I like the 6mmBR and variants (Dasher, BRX, 6BRA) with zero freebores.” He gets great results with 55-60 grain Sierras and Noslers with H322 powder: “I shot 55 Sierra Blitzking, 55 Nosler Ballistic Tip, and 60gr Sierra Varminter HP. H322 was the best powder. Jam ‘em 10 thou in the rifling — and of them — and man they were like magic.” Alex also feels the 6mm rifles are easier to tune than 22-caliber varmint rigs and the 6mm barrel throats last longer. He often puts an older 6mm match barrel on a varmint gun and it still holds quarter-MOA.
Alex recommends sticking with a 1:8″-twist even when shooting light 6mm bullets. The extra RPM makes the bullets MUCH more explosive on critters: “I’ve done one 1:13.5″-twist and I’ll never do that again. I’m not kidding, with the 8-twist it’s twice as energetic. It can lift those ground squirrels 20 feet in the air. With the 13.5-twist it’s not half that.”
About the Suppressor — The rifle is wearing a “can” in the photo. However, Alex tells us that he now avoids suppressors for most varmint work: “I didn’t like the suppressor — it put off so much heat that the mirage was terrible. With the heat mirage, after 5-10 shots you couldn’t see. I learned my lesson. I pulled that sucker off after the first time I shot it.”
3. 6mm Dasher in Convertible Laminated Stock
The 6mm Dasher has won many benchest matches, and it’s also an ultra-accurate varminting cartridge. This Dasher belong to Forum member MTLager who posted: “Here’s my baby — 6 Dasher with BAT SV action. First one built. Serial number PT1.” This impressive rig features a tack-driving, 1:8″-twist Brux Heavy Varmint contour barrel. This rig is “Smokin the 75gr V-Maxs” reports MTLager. The stock is very interesting. MTLager explains: “This is a Richard Franklin laminated blank made into a stock by J.T. Barber. It has a 3″-wide fore-end for varmint shooting. But I can change the front to 4″-width and a rear section can be removed.” The angled rear “toe” of the buttstock can be taken off, allowing a flat, straight bottom for benchrest competition.
4. Slick 17 Fireball with BAT Action and Stunning Stock
This rifle is almost too pretty to carry out into the varmint fields. Look at that wood! This handsome small-caliber varminter belongs to Forum member “20 TAC”. Chambered for the 17 Fireball wildcat (.221 Fireball necked down), this rig features a BAT Action, Jewell Trigger, and a custom exhibition-grade walnut stock sporting a true ebony fore-end cap. The checkering is exceptional. Owner 20 Tac report this rig “shoots 20 grain V-Max bullets with H4198 very well.” That’s a Nightforce scope on top.
5. 6mmBR in McMillan Stock with Krieger Barrel
This website stated 17 years ago as 6mmBR.com, so we had to include a classic 6mmBR Norma in today’s varmint rifle line-up. Forum member Powderbrake posted: “Here is my favorite varmint rifle — [a 6BR with] Stiller Predator V RBLP action, bedded in a McMillan stock.” This accurate varminter features a 1:8″-twist 6mm Krieger barrel and Jewell trigger. Up top is a Nightforce NXS 8-32x56mm scope. Below are the owner’s key gear items: Leica Laser-Rangefinding Binoculars, Smartphone with Applied Ballistics software, and Kestrel Weather Meter. Powderbrake told us he recently upgraded to a Model 5700 Kestrel with ballistics software and LiNK. (Editor: The $399.00 Kestrel 5700 has ballistics software, but if you want the full Applied Ballistics suite, order the $699.00 Kestrel 5700 Elite).
6. Efficient 20 Vartarg for Prairie Dog Adventures
The .20 Vartarg is based on the .221 Fireball case, necked down to .204 and slightly modified for extra capacity. This very efficient cartridge offers low recoil and great accuracy. It’s one of our first choices for ground squirrels and P-dogs out to 300 yards. 20 Vartarg here belongs to Forum Member DogBuster, an avid varminter based in Utah. He posted: “If I recall, I had a hot spot in this location — probably kilt 150+ prairie dogs that morning. The hay wagon helped too, offering added elevation.”
7. Long-barrel SAKO Action Varminter in .243 Super Rock Chucker
Here is another .243 wildcat, chambered for the .243 “Super Rock Chucker”. This long-barreled rig belongs to Forum member MikeGaiz. The rifle features a SAKO action fitted with a 30″ Kreiger barrel chambered for the .243 Super Rock Chucker. From what we have read, the .243 Super Rock Chucker is a .25-06 cartridge necked down to .243 (6mm). Yes this is a barrel burner, but it can definitely “reach out and touch” varmints at VERY long range. Owner Mike reports hits at 1275 yards on prairie dogs in South Dakota. This cartridge drives Sierra 6mm 85gr HPBTs at 3440 FPS. That’s serious speed for an 85-grainer.
8. AR-10 Custom in .243 Winchester
Forum Member Urban Rifleman calls this .243 AR10-platform rifle the “Goblin Killer”. This Gen 2 DPMS rifle features a Craddock Precision Bartlein 1:8″-twist 5R barrel chambered in .243 Winchester with a Tubb assymmetrical muzzle brake. Up front is the unique Tubb Bipod which reduces hop. The buttstock is a Magpul PRS Gen 2. The scope is a Leupold VX-3i LRP 6.5-20x50mm FFP TMR. We’re told this rig “will easily shoot 1/2 MOA, sometimes much smaller”.
Urban Rifleman produces a variety of great gun accessories sold through TheUrbanRiflemanStore.com. That green grip is his Urban Rifleman/Tubb ergonomic grip.

Have you tried IMR Enduron powders yet (IMR 4166, 4451, 4955, and 7977)? We’ve been impressed with what we’ve seen. IMR’s line of Enduron extruded powders offer excellent temp stability, reduced copper fouling, and good load density for many popular cartridges (such as .223 Rem, 6mmBR, .308 Win, .30-06, 300 WSM to name a few). Some of our Forum members have reported excellent results with IMR 4166 in the 6mmBR, Dasher, 6.5×47 Lapua and .308 Win. One member wrote: “in my 6.5×47… 4166 gives speeds and accuracy pretty much exactly the same as Varget.” And other shooters have observed reduced copper fouling with Enduron series powders, so IMR’s Enduron anti-fouling chemistry does seem to work.
Varmint hunters, big game hunters, match shooters and military snipers all seek powders that are insensitive to temperature changes. These powders all have it. This translates to point of impact and group size remaining the same, no matter what temperature conditions prevail. Another huge benefit is an additive that prevents copper fouling from building during dozens of rounds being fired. Here the advantage is top accuracy for longer periods of time, and less cleaning time.
A third major accomplishment with this technology is ideal load density. Experienced reloaders know that a case-filling load often delivers the most uniform velocities and best accuracy. We see this in popular match cartridges such as the 6PPC, 6mmBR, 6BRA, 6.5 Creedmoor and .308 Win. These new Enduron powders offer excellent “full case” load density for the most commonly used cartridges with popular bullets.
These three powders, IMR 4166, IMR 4451 and IMR 7977, are environmentally friendly by not having any ingredients harmful to the environment. Add to that, the three of them cover the most popular cartridges from .204 Ruger up to the mighty 500 Nitro Express, and the handloader “has it all”.

You have to admire someone with serious do-it-yourself skills. Not just hammer and nail skills, but formidable design and fabrication skills. Well Forum Member Dave D. (aka “AKShooter”) has a DIY skill set that might put some trained machinists to shame. You see, “DIY Dave” crafted his own pedestal front rest from scratch, using his own design and about $100.00 in materials (not counting the Edgewood front bag). Dave estimates he put 20 hours of labor into the project, but the end result was worth it: “This Do-It-Yourself rest drives like a dream. I’ve played with the Caldwell and a Sinclair, they have nothing on this one.”
How well can the little 6mm Dasher perform at 1000 yards when the 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″ ten-shot group shot at the Deep Creek Range outside 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 three inches.

Fire-forming all your own 6mm Dasher brass takes time, costs money (in bullets and powder), and consumes precious barrel life. Well there IS a better solution — you can have your new brass hydro-formed by 
With the Dasher since the new node (the sweet spot) was found at 33.4 grains, that resulted in a velocity of 3050 fps (a 125 fps velocity increase) from the same rifle setup. Not only did the velocity increase, but the SD was lowered to 3.6 with an ES of 13 (calculated over 28 shots). You read that right… 13 fps ES over 28 shots!
