Look and be amazed. What you are seeing is the smallest 5-Shot group ever shot in 1000-yard competition. And it is also perfectly centered for a 50-5X max score, yes ALL Xs. Brilliant! This amazing group was shot by Mike Wilson in July of 2018 with his 17-lb Light Gun, chambered for a 6mmBR wildcat he calls the 6 BRAW (BR Ackley Improved Wilson). This spectacular feat of accuracy demonstrates the potential of the 6BR family of cartridges even at 1000 yards. For his record group, Mike shot Vapor Trail 103-grain bullets in Lapua 6mmBR fire-formed brass. He loaded Hodgdon H4895 powder with CCI 450 primers. The action was a BAT, the barrel a Brux.
The Best 5-Shot 1000-Yard Group in History
Story based on report by Sam Hall
Look at that target by Mike Wilson. This is one of the most remarkable displays of accuracy (and precision) in the history of long range shooting. This past weekend, Mike (aka “GA. Dawg” in our Forum) drilled a truly spectacular 1.087-inch, 5-shot group at 1000 yards, all centered up in the X-Ring. Yes, you read that right, a group barely over an inch at 1000, shot in competition at an official IBS benchrest match on July 21, 2018. Note, the group was measured at the range at an even smaller 1.068″ (see target). However, as certified by the IBS as a IBS Light Gun World Record, the group is listed as 1.087″.
How small is that in angular measurement? Well 1 MOA at 1000 yards is 10.47 inches, so Mike’s 50-5X masterpiece is 0.1038 MOA! Yes that is an IBS group size AND score World Record. And it is also smaller than the current NBRSA 1000-yard 5-shot LG world record, 1.473″ by Bill Schrader in 2002. This best-ever 1K group* was shot at an IBS registered 1000-yard match at Hawks Ridge Gun Club in North Carolina. Other records have been shot at Hawks Ridge in the past, but this is the most jaw-dropping.

Sam Hall, past IBS National Champion and IBS 600-Yard Shooter of the Year, was stunned by Wilson’s accomplishment: “This is a truely awesome marksmanship feat — one of the best in history. I think I would trade all 14 of my 600-yard records for that one!”. Mike’s amazing target will be submitted for approval as new Group Size and Score IBS World Records. Official approval is pretty much a certainty. The previous 5-shot, 1000-yard IBS record is 1.397″ (50 score) by Tom Sarver in 2007. (The NBRSA 1000-Yard 5-shot LG record is 1.473″ by Bill Schrader in 2002.)
Posting on our Shooters’ Forum, Mike wrote: “Thanks everyone for the kind words. As humbling as this game is, when it comes together makes it all worthwhile! A very special THANK YOU to my traveling buddy, my son, Blake, and my wife Debra for allowing me to enjoy this crazy game.” Mike also wanted to thank his smiths and component suppliers.

World Record-Setting Cartridge and Load
Mike was shooting a 40-degree Improved version of the 6mmBR Norma cartridge. Long popular with Benchrest and 300M shooters, the 6mmBR was the original inspiration for this website. Yep, we started as www.6mmBR.com. The Improved version has extra capacity, allowing about 100 FPS more velocity when chambered with a long throat. For his record group, Mike shot Vapor Trail 103-grain bullets in Lapua brass. He loaded Hodgdon H4895 powder with CCI 450 (small rifle magnum) primers.
Praise from Fellow Competitors
Here are some reactions to Mike’s amazing group by our Forum members:
“Amazing target Mike Wilson! Your group might last forever as ‘the goal’ of 1000-yard Benchrest! Heck that’s a great target even at 600 yards.” — Mike J.
“Think about this for a second. That group was barely larger than the size of your index finger’s first digit and he printed it at 1000 Yards.” — Carlos
“Unbelievable!! Doing that under chosen prime conditions is an amazing feat but to do that in competition and to have everything to come together is just unbelievable. Amazing how far skill, precision, knowledge, and the products of this sport have come. Never thought we would see a group this small and well placed especially in the hills of North Carolina where the wind always blows. Congratulations. A true lifetime achievement.” — Yote Hunter
“I think that one will stand for a while. Hard work does pay off, but it don’t hurt to be one of the givers in the sport. Mike, you are ‘The Man’!” — Bill Shehane
“Awesome, awesome. Now the goal is to shoot UNDER an inch!” — Alex Wheeler
The 6mmBR Ackley Improved
Mike Wilson shot his spectacular group with a 40° Improved version of the 6mmBR cartridge with less body taper than a standard 6BR — the design is 0.463 at the body/shoulder junction (vs. 0.460 for standard 6BR). Mike calls his version of the 6BR Ackley a 6BRAW (“W” for Wilson). Sam Hall explained: “The 6BRAW is pretty much the same as a 6BRA or 6BR-AI (Ackley Improved). I sold the reamer to Mike last year. This has a 0.272 ‘No-Turn’ chamber with a 0.135 Freebore”.
This photo shows a 40° 6mmBR Ackley Improved (6BRA), as used by Tom Mousel in Deep Creek, Montana. Mike Wilson’s 6BRAW may be very slightly different. For Mousel’s 6BRA with 28″ Krieger barrel, the accuracy node is about 2980-2990 fps, so this gives up only 30-50 fps compared to typical Dasher velocities. Mike Wilson’s load runs about 2980 fps also.
In the past couple of years, the 6BR Ackley-type cartridges have been hugely successful in 600-yard and 1000-yard Benchrest. Sam Hall notes: “This year the little 6BR-AI has shot the smallest groups ever fired in 600-yard and 1000-yard competition. Back in April 2018, bullet-maker Bart Sauter, using a 6BRA, shot a 0.311″ 50-score 5-Shot group at 600 yards.” (Read Sauter Story). Bart’s stunning 0.05 MOA group is now the 600-yard IBS HG World Record.(Note: Bart’s target was originally measured at 0.282″ but was later IBS-certified at 0.311″.)
Mike used an Italian Lenzi rear bag. Mike says the super-slick nylon on the ears of this high quality rear bag make for better tracking. The ears provide support but don’t “grab” the stock, reports Mike.
More Comments by Fellow Shooters:
“Truly an amazing feat. The 5X was the icing on the cake! Many shooters would be very happy with that group size at 200 yards.” — Mr. Zero
“Words cannot adequately express how many of us feel about your magnificent accomplishment at 1000 yards. Congratulations — that is terrific!” — Gene Beggs
“Truly amazing … well done on a great achievement… RESPECT!” — Elardus
“Bravo Mike pour ce tir incroyable. Ton exploit est sur le forum de tir longue distance en France bonne continuation.” — Frederic Riso
* There are two North American sanctioning bodies for 1000-Yard Benchrest, the IBS and the NBRSA. The previous 5-shot, 1000-yard IBS record is 1.397″ (50 score) by Tom Sarver in 2007. The existing NBRSA 1000-Yard 5-shot Light Gun record is 1.473″, shot by Bill Schrader in 2002.

Kulzer Sets Eight IBS 1000-Yard IBS Benchrest Records with 6 BRA Rifle Report by Alex Wheeler
In 2021, Glenn Kulzer of Dillon, Montana had a season that will go down in 1000-Yard Benchrest history. Glenn set eight IBS records in 2021 at the Deep Creek range in Missoula, and then was named IBS 1K Shooter of the Year. What makes this so incredible is not just the number of records but the records themselves. Normally when a world record small group is shot that’s a singular event — never accompanied by Aggregate records set by the same shooter. Glenn’s IBS record small group wasn’t a one-time lucky string. Consider this — Glenn nailed that historic small group, but also recorded multiple IBS Aggregate records in 2021. And Glenn set these IBS Heavy Gun records actually using his 6 BRA (6mmBR Ackley) Light Gun! Mighty impressive.
[Editor: These were impressive records that have stood the test of time. A quick search of the IBS record site shows Glenn Kulzer still holds six of the ten listed IBS 1000-yard Heavy Gun records. Plus, Glenn broke the Light Gun 20-Target Agg group record, but that was later bettered by Tom Mousel.]
1000-yard Benchrest Aggregate records represent a series of targets shot over the course of multiple matches during a season. That really takes any luck out of the equation. You have to keep the rifle shooting at its peak all year long. It’s the ultimate test of accuracy. But the small groups do get the most notice and Glenn also broke the small group record with a remarkable 2.6853″ 10-shot group (photo below).

NOTE: Two of these records have been broken. The HG 20-Target Score Aggregate record is now 95.55, set by Blake Wilson. And the LG 20-Target Group Agg record is now 4.3825″, set by Tom Mousel.
This IBS record 1000-yard group, and Glenn’s other IBS records, were shot with Roy Hunter’s 103gr “A” bullet, Hodgdon H4895 powder, CCI BR4 primers, and Alpha Munitions 6 BRA brass. However, Glenn does use Lapua brass for some other 6 BRA rifles.
Glenn’s record-setting rifle is a Light Gun with a common setup used in long range Benchrest. The rig features a Borden BRM drop-port action with a Bix’n Andy trigger. The action is glued and screwed into a industrial wood laminate Deep Creek Tracker stock, a predecessor of the McMillan LRB. The Krieger barrel is a 4-groove, 1:8″-twist Heavy Varmint contour chambered for the 6 BRA (6mmBR Ackley) cartridge. All of Glenn’s rifles are topped with Vortex Golden Eagle scopes. Glenn notes that his Vortex Golden Eagles have show excellent point-of-aim stability when tested with a scope checker. The front rest was a Sinclair competition with Edgewood front bag, Field & Cave outfitters front rest plate, and speed screw. For rear support Glenn uses an Edgewood LRB rear bag.
Loading Procedures for Record-Setting 1000-Yard Shooting
Glenn’s loading process is pretty simple. He full-length sizes every time, bumping the shoulders back about .003″. Powder is weighed to the kernel, and bullets are seated with a Wilson seater. NOTE: Glenn does does not anneal his brass. He sorts primers by weight but does not otherwise measure them by dimensions. He seats the primers by feel using a relatively inexpensive primer seating tool — nothing fancy.
Glenn worked up a trim-and-point recipe for this lot of bullets based on group size. Load development is all performed at 1000 yards using the group ladder method. Glenn’s record load ended up being 30.3 grains of H4985 powder with the 103gr bullet seated very far into the rifling with .005″ of neck tension. This gave a velocity of 3030 fps in the 28″ Krieger.
Glenn shot Alpha Munitions 6 BRA brass all year with the .080″ flash hole. This year he shot Roy Hunter’s 103gr “A” bullet set quite deep into the rifling. NOTE: This deep jam has proven to be very stable IF you barrel likes it. Glenn used CCI BR4 primers and Hodgdon H4895 with .005″ of neck tension. His load delivered 3030 fps out of a 28″ barrel. NOTE: This is a “HIGH NODE” that may not be possible in an average barrel with different brass. Many 6 BRA shooters are reaching a 3000+ fps node, but you should always start low and work up. Some 6 BRA barrels will max out at 2950 FPS with 103-108gr bullets.

Setting Records in June 2021 Report by Alex Wheeler
It was a typical match for June, nothing unique about it. Saturday was actually looking to be a really great day. Overall it was good but not great. Sunday had a clear blue sky with bright sun. I looked through a couple of scopes before the match and it was milky. I probably would have shot that relay at 30-35 power. But somehow Glenn Kulzer was able to pull off the best heavy gun group ever shot in 1000-yard IBS competition. With that group Glenn also broke the 6-match Group Aggregate record. The group was no fluke, this rifle also shot great in previous matches with small groups at 1000. To my knowledge this may be the only time a small group record AND an Aggregate record were broken in the same season by the same gun. The ultimate achievement.
On June 13, 2021, Glenn shot a 2.6583″ 10-shot group, all shots in the 10 Ring for a 100 score. This now stands as the current IBS Heavy Gun 1000-Yard 10-shot group record AND score record. It is also part of new Aggregate Records listed above.
About Glenn Kulzer — Rising Star in the Long-Range Benchrest Game by Alex Wheeler
Kulzer is a pharmacist in Dillon, Montana. The attention to detail required for his job crosses over to Long-Range Benchrest. He started off a very competitive shooter right from the start. I have said it many times, but benchrest is not an elitist sport. Hard work and dedication will always rise to the top. Glenn took the sport seriously from the beginning. Accordingly, he displayed a rapid learning curve and quickly surpassed some of his mentors in match results. Glenn tunes mostly at 1000 yards using the Deep Creek variation of ladder testing. He will also load and tune at the range to try and nail the best tune for the conditions. Again, it all about the work done by competitors. But Glenn’s success shows that a bright, hard-working shooter can rise to the top of the game in just a few seasons.

Do primer types make a significant difference in accuracy or vertical dispersion at long range? The answer is “maybe”. Here’s one anecdotal study that tracked vertical variance among six different primer types. The tester is a good shooter with a very accurate rifle — four of the six 4-shot groups were under 2″ at 500 yards. This test doesn’t settle the question, but does suggest that it may be worth trying a few different primer types with your match ammo.
Here is a very interesting test for the 6 BRA (6mmBR Ackley) cartridge. Forum member James Phillips, a talented long-range benchrest shooter, tested SIX different primer types from three different manufacturers. To help determine vertical dispersion, James set his target out at 500 yards. He then proceeded to shoot 4-shot groups, in order, with each primer type. Velocities were recorded with a chrono. The photo above shows the results. James says: “I’ll retest the best two for accuracy and consistency with 10 shots each”. CLICK HERE for full-screen target photo.
As you can see, ALL the groups are pretty impressive. The smallest groups, 1.253″, was shot with CCI 400 primers. Next best (and very close) was CCI BR4, at 1.275″ for four shots. The “flat line” winner was the Remington 7.5, at upper left. There was almost no vertical.

CARTRIDGE: 6mmBR Ackley, aka 6 BRA. Parent case is 6mmBR Norma. The 6 BRA is fire-formed to create a 40-degree shoulder and less body taper. Capacity is increased, but the neck is longer than a 6mm Dasher. The capacity is enough to get to the 2950+ FPS accuracy node. Some shooters say the 6 BRA is more forgiving than the 6mm Dasher. The 6 BRA is certainly easier to fire-form.
TEST REPORT — Conditions, Shooting Method, Loading Method
Tester James Phillips posted this report in ourShooters’ Forum:
Conditions: The testing was done in the morning over flags. The flags never moved or even twitched. I had as perfect conditions as I could have asked for. It was overcast so no mirage and no wind. There were no other shooters, just me.
Test Procedure: Each shot was precisely shot at my pace and centered the best possible using my Nightforce 15-55X scope. I did not use the round-robin method. Each four-shot group with the same was shot at one time. Then I moved onto the next primer. Everything felt right for each and every shot fired today. Of course I could repeat the test tomorrow and it could be exact opposite of today’s test. We can chase this forever. But [soon] I’m going to test the BR4 and 400 primer… for best accuracy and consistency for 10 shots each.
How Rounds Were Loaded: Each load was weighed to one (1) kernel of powder. So I know that’s as good as I can weigh them. Each bullet seating force was within 1# on my 21st Century hydraulic arbor press.
Previous Initial Load Testing: All groups were shot with 31.1 grains of H4895. During initial load testing I settled in on the Sellier & Bellot primer to finalize everything as it showed more promise over the CCI 450 Magnum I also tried. I was actually surprised to have seen the higher ES and SD from that primer today along with the vertical shown. [Editor: Look carefully — one shot from the CCI 450 is right in the center black diamond, stretching the vertical. By contrast the Rem 7.5 had almost no vertical.]
Velocity and NODE Considerations: I was about 5-6 FPS above what appeared to been my optimum velocity of 2943-2945 FPS, so I’ll test 5 shots of 31.0 and 5 of 31.1 and see what happens from there. I can only assume my velocities where higher due to the higher humidity and of course temps were 5 degrees warmer this morning as well. It wasn’t far off but I noticed it.

600/1000 Benchrest Light Gun for Richard Schatz in 6 BRA
This blue benchrest rig was crafted by Alex Wheeler for ace benchrest competitor Richard Schatz, a past 600-yard IBS Shooter of the Year. Richard’s new 600/1000-yard Light Gun features a Krieger barrel chambered in 6 BRA (40° Ackley version of 6mmBR Norma). That Krieger is mated to a 1.550″ BAT B action, ignition-timed for smooth bolt close and increased accuracy. The trigger is the sophisticated Bix’n Andy. Schatz’s BAT is glued and screwed into a Wheeler LRB stock, with aluminum rails and adjustable metal “tracking rudder” on the toe of the stock. The rudder can be adjusted side to side to ensure optimal tracking, while the rudder’s vertical angle can be adjusted slightly with shims.
Hand-Crafted Thumbhole-Stocked Rifle Chambered in 6 PPC
Forum Member Grimstod offered this handsome 6 PPC custom with a beautiful, hand-made thumbhole stock: “This was fully accurized with Premier Accuracy recoil lug installed. Really makes these shoot a lot better. It features a Kelbly Panda action with Hart barrel and glass bedding. Trigger fall was perfect to start and we have to give Ian Kelbly big thumbs up for making every action perfectly timed.” On top is a March competition scope.

A Wicked Accurate Big Dawg in 28 Nosler
This 28 Nosler Benchrest rifle looks good and shoots even better — check out that 20-shot target shot at 200 yards! You can’t argue with that…
Belonging to Forum member LA50Shooter, this rig is chambered in 28 Nosler, with metal work by Gre-Tan Rifles. The action is a BAT Model “L” 1.650 Octagon with a 30 MOA scope rail, running a Jewell BR Trigger. The stock, from D&B Supply, is a Shehane Big Dawg Tracker with 5″ fore-end. Color scheme is “Field & Stream” Rutland laminate. This big rig boasts FOUR 34″ Benchmark barrels (1.5″ for seven inches tapering to 1.225″ at muzzle).

Kulzer Sets Eight New IBS 1000-Yard IBS Benchrest Records with 6 BRA Rifle Report by Alex Wheeler
2021 was a banner year for 1000-yard Benchrest. Glenn Kulzer of Dillon, Montana had a season that will go down in history. Glenn set eight IBS records in 2021 at the Deep Creek range in Missoula, and then was named IBS 1K Shooter of the Year. What makes this so incredible is not just the number of records but the records themselves. Normally when a world record small group is shot that’s a singular event — never accompanied by Aggregate records set by the same shooter. Glenn’s IBS record small group wasn’t a one-time lucky string. Consider this — Glenn nailed that historic small group, but also recorded multiple IBS Aggregate records in 2021. And Glenn set these IBS Heavy Gun records actually using his 6 BRA (6mmBR Ackley) Light Gun! Mighty impressive.
1000-yard Benchrest Aggregate records represent a series of targets shot over the course of multiple matches during a season. That really takes any luck out of the equation. You have to keep the rifle shooting at its peak all year long. It’s the ultimate test of accuracy. But the small groups do get the most notice and Glenn also broke the small group record with a remarkable 2.6853″ 10-shot group (photo below).

This IBS record 1000-yard group, and Glenn’s other IBS records, were shot with Roy Hunter’s 103gr “A” bullet, Hodgdon H4895 powder, CCI BR4 primers, and Alpha Munitions 6 BRA brass. However, Glenn does use Lapua brass for some other 6 BRA rifles.
Glenn’s record-setting rifle is a Light Gun with a common setup used in long range Benchrest. The rig features a Borden BRM drop-port action with a Bix’n Andy trigger.

Glenn’s record load ended up being 30.3 grains of H4985 powder with the 103gr bullet seated very far into the rifling with .005″ of neck tension. This gave a velocity of 3030 fps in the 28″ Krieger.
Glenn shot Alpha Munitions 6 BRA brass all year with the .080″ flash hole. This year he shot Roy Hunter’s 103gr “A” bullet set quite deep into the rifling. NOTE: This deep jam has proven to be very stable IF you barrel likes it. Glenn used CCI BR4 primers and Hodgdon H4895 with .005″ of neck tension. His load delivered 3030 fps out of a 28″ barrel. NOTE: This is a “HIGH NODE” that may not be possible in an average barrel with different brass. Many 6 BRA shooters are reaching a 3000+ fps node, but you should always start low and work up. Some 6 BRA barrels will max out at 2950 FPS with 103-108gr bullets.

Setting Records in June 2021 Report by Alex Wheeler
It was a typical match for June, nothing unique about it. Saturday was actually looking to be a really great day. Overall it was good but not great. Sunday had a clear blue sky with bright sun. I looked through a couple of scopes before the match and it was milky. I probably would have shot that relay at 30-35 power. But somehow Glenn Kulzer was able to pull off the best heavy gun group ever shot in 1000-yard IBS competition. With that group Glenn also broke the 6-match Group Aggregate record. The group was no fluke, this rifle also shot great in previous matches with small groups at 1000. To my knowledge this may be the only time a small group record AND an Aggregate record were broken in the same season by the same gun. The ultimate achievement.
On June 13, 2021, Glenn shot a 2.6583″ 10-shot group, all shots in the 10 Ring for a 100 score. This now stands as the current IBS Heavy Gun 1000-Yard 10-shot group record AND score record. It is also part of new Aggregate Records listed above.
About Glenn Kulzer — Rising Star in the Long-Range Benchrest Game by Alex Wheeler
Kulzer is a pharmacist in Dillon, Montana. The attention to detail required for his job crosses over to Long-Range Benchrest. He started off a very competitive shooter right from the start. I have said it many times, but benchrest is not an elitist sport. Hard work and dedication will always rise to the top. Glenn took the sport seriously from the beginning. Accordingly, he displayed a rapid learning curve and quickly surpassed some of his mentors in match results. Glenn tunes mostly at 1000 yards using the Deep Creek variation of ladder testing. He will also load and tune at the range to try and nail the best tune for the conditions. Again, it all about the work done by competitors. But Glenn’s success shows that a bright, hard-working shooter can rise to the top of the game in just a few seasons.

The Tack Driver Showdown is a 300 meter, one-of-a-kind match designed to determine the most accurate rifles in the world regardless of discipline or class. The 2021 Tack Driver II event had 80 of the world’s top competitors representing several disciplines (Short-Range for Group, Short-Range for Score, UBR, F-Class, 600-yd and 1000-yd Benchrest) with calibers/cartridge types ranging from .22 PPC to .300 WSM.
IMPORTANT: Folks, if you shoot competitive benchrest, please DO watch the First Video below. It is full of invaluable information and shooting tips. As Bart holds multiple world records, you should listen to what he says. This is, without question, one of most informative benchrest videos I have ever seen in 18 years of running this site. — EDITOR
This year the match was VERY challenging, with tough, very windy conditions and low temperatures. The overall winner of the Grand Aggregate was bullet-maker Bart Sauter, shown above. Bart was shooting his wickedly accurate 6 BRA rifle with 103gr bullets of his own making. Bart demonstrated that a 6 BRA cartridge with long bullets can beat a 6 PPC, at least at 300 meters when the wind is fierce.
WATCH THIS! Folks, if you are a benchrest competitor, you absolutely should watch this video. This offers very important insights you won’t find anywhere else. The first five minutes shows very important advice on setting up your rest and bags. Starting at the 10-minute mark, Bart shows how he shoots the rifle, with rapid manual reloads. At the very end, 15:55+ Bart runs five (5) shots in 9 seconds!
Match Results — What Cartridge Types Dominated
Bart reports: “It’s interesting to see the calibers/cartridges in the Top 10 of each category. The Group Match was in fact won by the 6 PPC. However, look at the top 5. Three of the Top 5 are NOT 6 PPCs — that’s notable. The Score Match was won with a .30 WW (I have no clue what that is). There were two .30 calibers in the Top 5 and three in the Top 10. The Grand Aggregate was won with a 6 BRA. I think it’s noteworthy the Top 5 had two 6 PPCs, two 6 BRAs and a .30 WW! That’s a pretty good mix. The Top 10 had a variety of 6MMs and one .30 caliber. That’s another surprise.”

Leveling the Playing Field — What Works Best at 300 Meters Commentary by Bart Sauter
There has been a long standing debate in the shooting world as to whether mid-range/long-range cartridges such as the Dasher, 6 BRA, and 6mmBR are accurate enough to compete against the 6 PPC or 30 BR at shorter distances. The problem has been finding a format that allows the both short-range and longer-range cartridges to compete on a level playing field. The Tack Driver match addresses the problem by moving the distance to 300 meters (approximately 329 yards). This is a bit farther than short range group and score matches which are typically shot at 100 and 200 yards. While the mid-range/long range cartridges shoot primarily at 600 and 1000 yards.
Cartridges Left to Right: 6 PPC, 30 BR, 6mmBR, 6 BRA, 6 DASHER. Those five cartridges represent 85% of cartridge types used at the Tack Driver II match.
Another piece of the puzzle is the type of match — group vs. score. Short Range matches consist of either a group or score match. In group shooting you’re trying to shoot as small of a group as possible (5- or 10-Shot group). Unlike score it doesn’t matter where the group forms on the target. However, in score competition the goal is to hit five individual bullseyes per target, preferably dead center. Score matches are won by the highest point total while group matches are won by the smallest aggregate (smallest average of total groups shot).
Things are different for longer range competitions. 600-yard and 1000-yard Benchrest competitors shoot for score AND group simultaneously on the same target. In other words competitors are trying to shoot the smallest group in the middle of the bullseye for the highest point total. The Tack Driver addresses this problem by having an equal number of score targets and group size targets. Tack Driver II had 5 score targets and 5 group targets at 300 meters, so neither discipline is favored.

Tack Driver II-Winning 6 BRA Rifle — Components Explained
Questions and Answers with Bart Sauter
Match Prep, Cartridge Choice, Comparative Wind Drift, Reloading Gear, Wind Conditions and more…
Q: How did you prepare for the match?
Bart: My good friend and shooting buddy, Jim Chaney, built a target frame which was placed at 300 meters for practice before the match. Our two biggest concerns about the match were: 1) staying competitive during the score portion; and 2) being able to see bullet holes during heavy mirage. The range is mostly South Carolina sand and faces southeast (you can get sun in your eyes). It has a notorious reputation for heavy mirage. So much so that seeing bullet holes can be an issue. Many shooters were swayed to shoot .30 calibers because the holes are easier to see. In fact, when the sun came out for the last couple of targets, several shooters complained they couldn’t see their shots on paper.
Q: I know you’ve shot a 6 PPC for years? What made you decide to go with a 6 BRA?
Bart: Well several things. During practice I bounced back and forth, playing with the 6 PPC and the 6 BRA. My shooting buddy Jim shot his 6 PPC. One of the things I noticed was my 6 BRA consistently edged my 6 PPC and and Jim’s 6 PPC in group size.
The Drift Test — The real eye-opener came when Jim and I conducted a drift test at 200 yards comparing the 6 PPC with 68gr Boattail Avengers to my 6 BRA with 103gr Bart’s Hammers. For the test both rifles were tuned as well as possible. The idea was for both shooters to hold the same point of aim for each shot (total of 5 per sequence). The shots were fired simultaneously by conducting a count down for example “One, Two, Three, FIRE!” Winds were 7 to 10 mph.
Bart (foreground) and Jim Chaney conducting comparative wind-drift tests with 6 PPC and 6 BRA prior to Tack Driver II Match.
Each shot was intentionally fired in a different wind condition over flags. The first 3 shots from the 6 BRA formed a nice 0.300″ group while the 6PPC spread out to a 0.650″. The final two shots were fired in a hard crosswind pushing to the right then a hard crosswind to the left. The 6 PPC was pushed to over a 1.6 inch group while the 6 BRA kept them to around an 0.850″. The test was so conclusive that during the drive to the match Jim abandoned his 6 PPC, and we doubled up on my 6 BRA.
Comparative Wind Drift Explained — 6 PPC vs. 6 BRA
Q: That explains why you chose the 6 BRA, but how did you meet the challenge of seeing 6mm bullet holes despite bad mirage?
Bart: Jim and I played with several different scopes trying to see what would work best. The mirage at my place can be substantial. Around September I purchased the new Valdada 10-60x56mm Precision scope with 40mm tube. This scope is amazing, not only optically, but rock solid accuracy-wise. So if anything was going to work to see bullet holes, it’s this scope. As it turned out, I had no problem seeing my shots on the Tack Driver II targets while others struggled on the last couple of targets.
Q: Did you preload for the match?
Bart: No. I’ve never been to this range so I wasn’t sure where I needed to be load-wise. Also the forecast was calling for cool temperatures and rain, so I had no clue. The plan was to get there early and start tuning soon as the range opened for practice on Friday. It took about 15 shots to verify that the same velocities and load that I ran at a previous Memphis match would work for the Tack Driver II.
Q: If you weren’t preloaded, did you load at the range?
Bart: Not exactly, I didn’t preload for the match at home but I did preload at the hotel. I brought 300 sized and primed cases and everything needed to reload. So after practice, it was back to the hotel to load. Below is my set-up at the hotel.
Reloading setup at hotel: K&M Arbor Press with seating pressure gauge, Wilson Bullet Seater, AutoTrickler V3 Powder trickler/scale housed in a portable, wind-proof loading box.
I loaded cases with Hodgdon H4895 in one-tenth grain increments (0.3 grains total spread) to shoot over the course of the day. I expected that a three-tenth spread would be enough to keep the rifle in tune over the forecast 20-25 degree temperature range. As a backup plan in case the load went completely sideways we hauled all the loading gear to the range each morning. I kept 100 sized and primed cases ready if needed. Fortunately we did not have to use them. We were able to use the three different, prepared loads throughout the day, changing as the ambient temperature rose (highest charge in morning).
Q: What were conditions like?
Bart: The conditions at Tack Driver II for both days were tough! We had switchy head winds ranging from 15 to 25 mph with occasional gusts to 30 mph. Temperature started with morning lows in the high 30s and warmed to a high around 50. The forecast called for rain both days but fortunately it didn’t materialize during the competition.
Bart Sauter checks out conditions during the match. Winds were switchy with gusts to 30 MPH.
Q: Do you have any observations or take-aways from the match?
Bart: Yes, I do! Jim Cline and crew puts on one hell of a match — very well organized and professionally run. And, most of all, the Tack Driver II was fun. Jim keeps things rolling and he has a gift for winding shooters up and getting the competitive juices going. For example he told three of the Top 6 PPC shooters, “If Bart beats you with that 6 BRA, all of you are getting autographed T-shirts at the award ceremony”.
True to his word, Jim Cline presents (L to R) Roy Hunter, Jeff Pineheart, and Wayne Cambell, with their Bart Sauter-autographed Tack Driver T-shirts. (Cline stands behind the trio.)
About Bart Sauter and Bart’s Custom Bullets
Our philosophy at Bart’s Custom Bullets is to take care of our customers, don’t cut corners, test everything, and never sell a bullet I wouldn’t be proud to take to a match. We started making bullets in 2000, while I was still in the Army. From the beginning Kim (my wife) and I decided to spend whatever It would take to get the best equipment available. We built a range for testing at every location the Army sent us. It’s been a successful combination.
Our bullets have set well over 50 world records and have won every major competition in short range. Now we are making strides to accomplish the same thing in Long Range.
Bullet Design — What Does the Future Hold? We have come a long way in the design and manufacturing of bullets. Everything has improved to include high-quality presses, jackets with close to zero run-out, and bullet dies that are straighter and more concentric than ever before. I believe we are close to the apex of designing bullets that shoot from 100 out to 1000 yards. Any improvement at this point will be incremental. In my opinion, the bullets we make right now are capable of shooting a 0.500″ group at 1000 yards (without wind effects). That probably sounds crazy to a lot of shooters. But I think the capability currently exists. It’s just going to take a special gun, barrel, shooter and condition combination to see it. Now bullets for Extreme Long Range (ELR) could be a new frontier for bullet design.

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.

After owning three different rifles with BAT actions, I have become a loyal fan of BAT Machine quality and customer service. Back in 2009, I traded my BAT/Scoville for the BAT/Leonard that I currently shoot. This rifle has a long history and Terry Leonard told me that “Old 87″ (as I have named it) was one of the earlier BATs that he stocked. He wrapped the stock in fiberglass and used 2-part epoxy back then. I must say that this rifle has held up remarkably well since it dates back to the 1990s. The action is a RB/LP/RE octagon Model B with .308 bolt-face.
Rifle Has Multiple Barrels for Multiple Disciplines
With this gun, I have shot several barrels of different calibers (.22 PPC, .22 PPC-short .095, 6mm PPC, 6XC, 6mm Dasher, .30BR, and will soon have a 6 BR-AI). It has been an exceptionally accurate rifle in several disciplines. In the hands of previous owners, it earned several Hall-of-Fame (HOF) points, and a “middle-of-the-pack” shooter (me) even received a HOF point with this rifle.
For most of its life, Old 87 served as a short range benchrest rifle, but I have used it for the last few years as a 600-yard rifle with the 6mm Dasher barrel. I was lucky enough to earn the Shooter of the Year award at the Prince Memorial Range in Louisiana for 2016.
After shooting my two Dasher barrels for last eight years, I have noticed a drop-off in accuracy at 600 yards. A decision had to be made — get a new barrel or sell the rifle and retire from competition. I am in my late 70s and my competition days are limited due mainly to a chronic neck problem. After mulling over the decision to retire or not, I decided to give Old 87 one more year. Here is the story of how we upgraded the old war-horse.
Old 87 REBORN — Upgrading with New Components
I prefer cut-rifled barrels with four lands and grooves and have had success with .236 bore diameters and 1:8″ twist in long range rifles. I searched for barrels meeting those parameters and found a suitable BRUX at Bugholes.com (Southern Precision Rifles).
The 6BR-AI Option — Easy Fire Forming
I thought about having Billy Stevens chamber it for the Dasher, but decided to try something new. There seems to be a lot of interest in the 6BR-AI and I said, “Why not?” Well, I bought a shortened Dasher die from Harrell’s and will use my Wilson Dasher seating die. Bart Sauter was kind enough to let me use his reamer for chambering.
Fitting a New Roller-Type Cocking Piece on Older BAT Action
Since I was into the project this deep, I called Mike Ezell and ordered one of his Tungsten powder-dampened tuners. Since Old 87 had thousands of rounds since the firing pin spring has been replaced, I decided that it was probably needed. Well, I got to thinking (very dangerous) and asked Daryle Thom if it would be feasible to put a roller-type cocking piece and a new firing pin spring on such an old action.
The folks at BAT are very accommodating and they said that it would be no problem with such a conversion. While my bolt was in Idaho, the barrel with Ezell tuner arrived and I could not shoot it. However, my friend Jeff Turner loaned me his BAT bolt to see if it would work. Although the rifles differ in age by 15 or more years, the borrowed bolt worked perfectly in my rifle. This is a testimony to the great machine work performed at BAT Machine.
New Bolt Roller Tail-Piece Makes a Big Difference in Cocking Effort
With the borrowed bolt I managed to fire-form 50 rounds and get them ready for our 600-yard match on September 16. The folks at BAT quickly fixed my bolt by replacing the mainspring and ejector spring, polishing the ejector, and replacing the tail-piece with their roller type. Pictured below is this tail piece that makes a remarkable difference in the force needed to cock the action. It is amazing what this little wheel can do… even when placed in a 25+ year old action.
Working with the Ezell Barrel Tuner — Small Increments Work Best
Also, I would like to congratulate Mike Ezell on his new tuner which contains powdered Tungsten. It is easy to set up and Mike will help a buyer get maximum effectiveness from the unit. Just give him a call. Below is a picture of the tuner. I was lucky enough to have some time to “play” with it before the match.
Talking about the tuner, Mike writes: “Our new barrel tuners… PDT stands for particle dampening technology. The science is there, we just applied it to a barrel tuner. The advantages are a wider tune window and more efficient control of barrel harmonics…in a tuner design that actually looks good.”
Mike advised me to set the tuner by turning it all the way into the shoulder and then come out to zero or the second time zero comes up if there is not at least half of a turn between the shoulder and the first zero. It is best to start with a proven load and adjust the tuner from that load. As unlikely as it seems, a rifle can go from a good tune to a very poor tune with only 5 marks (.005”) and vice versa.
Mike cautions those who use his tuner to NOT make adjustments which are too large. As a matter of fact, he recommends adjustments of .001 inch at a time. Ezell’s tuners are screwed onto the barrel with .900” by 32 threads per inch and has 32 marks on the circumference of the tuner. Therefore, each mark moves the tuner in or out by .001 inch. There are three set screws with Teflon tips which provide friction for the tuner on the threads. Do not tighten the screws so tight as they damage the fine threads.
If you want the smoothest bolt possible for your BAT, call or e-mail Daryle or Bruce Thom at BAT Machine and discuss your needs with them. I am sure glad that I did. If you want a state-of-the-Art tuner for your barrel, give Mike Ezell a call or visit his Ezell Custom Rifles Facebook Page.
— Good shooting, James Mock
Share the post "6BR Ackley Revival for Benchrest Rifle from 1990s"
Look and be amazed. What you are seeing is the smallest 5-Shot group ever shot in 1000-yard competition. And it is also perfectly centered for a 50-5X max score, yes ALL Xs. Brilliant! This amazing group was shot by Mike Wilson in July of 2018 with his 17-lb Light Gun, chambered for a 6mmBR wildcat he calls the 6 BRAW (BR Ackley Improved Wilson). This spectacular feat of accuracy demonstrates the potential of the 6BR family of cartridges even at 1000 yards. For his record group, Mike shot Vapor Trail 103-grain bullets in Lapua 6mmBR fire-formed brass. He loaded Hodgdon H4895 powder with CCI 450 primers. The action was a BAT, the barrel a Brux.
The Best 5-Shot 1000-Yard Group in History
Story based on report by Sam Hall
Look at that target by Mike Wilson. This is one of the most remarkable displays of accuracy (and precision) in the history of long range shooting. This past weekend, Mike (aka “GA. Dawg” in our Forum) drilled a truly spectacular 1.087-inch, 5-shot group at 1000 yards, all centered up in the X-Ring. Yes, you read that right, a group barely over an inch at 1000, shot in competition at an official IBS benchrest match on July 21, 2018. Note, the group was measured at the range at an even smaller 1.068″ (see target). However, as certified by the IBS as a IBS Light Gun World Record, the group is listed as 1.087″.
How small is that in angular measurement? Well 1 MOA at 1000 yards is 10.47 inches, so Mike’s 50-5X masterpiece is 0.1038 MOA! Yes that is an IBS group size AND score World Record. And it is also smaller than the current NBRSA 1000-yard 5-shot LG world record, 1.473″ by Bill Schrader in 2002. This best-ever 1K group* was shot at an IBS registered 1000-yard match at Hawks Ridge Gun Club in North Carolina. Other records have been shot at Hawks Ridge in the past, but this is the most jaw-dropping.
Sam Hall (left, green shirt) holds record target by Mike Wilson (right, white shirt).
Sam Hall, past IBS National Champion and IBS 600-Yard Shooter of the Year, was stunned by Wilson’s accomplishment: “This is a truely awesome marksmanship feat — one of the best in history. I think I would trade all 14 of my 600-yard records for that one!”. Mike’s amazing target will be submitted for approval as new Group Size and Score IBS World Records. Official approval is pretty much a certainty. The previous 5-shot, 1000-yard IBS record is 1.397″ (50 score) by Tom Sarver in 2007. (The NBRSA 1000-Yard 5-shot LG record is 1.473″ by Bill Schrader in 2002.)
Posting on our Shooters’ Forum, Mike wrote: “Thanks everyone for the kind words. As humbling as this game is, when it comes together makes it all worthwhile! A very special THANK YOU to my traveling buddy, my son, Blake, and my wife Debra for allowing me to enjoy this crazy game.” Mike also wanted to thank his smiths and component suppliers.

World Record-Setting Cartridge and Load
Mike was shooting a 40-degree Improved version of the 6mmBR Norma cartridge. Long popular with Benchrest and 300M shooters, the 6mmBR was the original inspiration for this website. Yep, we started as www.6mmBR.com. The Improved version has extra capacity, allowing about 100 FPS more velocity when chambered with a long throat. For his record group, Mike shot Vapor Trail 103-grain bullets in Lapua brass. He loaded Hodgdon H4895 powder with CCI 450 (small rifle magnum) primers.
Praise from Fellow Competitors
Here are some reactions to Mike’s amazing group by our Forum members:
“Amazing target Mike Wilson! Your group might last forever as ‘the goal’ of 1000-yard Benchrest! Heck that’s a great target even at 600 yards.” — Mike J.
“Think about this for a second. That group was barely larger than the size of your index finger’s first digit and he printed it at 1000 Yards.” — Carlos
“Unbelievable!! Doing that under chosen prime conditions is an amazing feat but to do that in competition and to have everything to come together is just unbelievable. Amazing how far skill, precision, knowledge, and the products of this sport have come. Never thought we would see a group this small and well placed especially in the hills of North Carolina where the wind always blows. Congratulations. A true lifetime achievement.” — Yote Hunter
“I think that one will stand for a while. Hard work does pay off, but it don’t hurt to be one of the givers in the sport. Mike, you are ‘The Man’!” — Bill Shehane
“Awesome, awesome. Now the goal is to shoot UNDER an inch!” — Alex Wheeler
The 6mmBR Ackley Improved
Mike Wilson shot his spectacular group with a 40° Improved version of the 6mmBR cartridge with less body taper than a standard 6BR — the design is 0.463 at the body/shoulder junction (vs. 0.460 for standard 6BR). Mike calls his version of the 6BR Ackley a 6BRAW (“W” for Wilson). Sam Hall explained: “The 6BRAW is pretty much the same as a 6BRA or 6BR-AI (Ackley Improved). I sold the reamer to Mike last year. This has a 0.272 ‘No-Turn’ chamber with a 0.135 Freebore”.
This photo shows a 40° 6mmBR Ackley Improved (6BRA), as used by Tom Mousel in Deep Creek, Montana. Mike Wilson’s 6BRAW may be very slightly different. For Mousel’s 6BRA with 28″ Krieger barrel, the accuracy node is about 2980-2990 fps, so this gives up only 30-50 fps compared to typical Dasher velocities. Mike Wilson’s load runs about 2980 fps also.
In the past couple of years, the 6BR Ackley-type cartridges have been hugely successful in 600-yard and 1000-yard Benchrest. Sam Hall notes: “This year the little 6BR-AI has shot the smallest groups ever fired in 600-yard and 1000-yard competition. Back in April 2018, bullet-maker Bart Sauter, using a 6BRA, shot a 0.311″ 50-score 5-Shot group at 600 yards.” (Read Sauter Story). Bart’s stunning 0.05 MOA group is now the 600-yard IBS HG World Record.(Note: Bart’s target was originally measured at 0.282″ but was later IBS-certified at 0.311″.)
Mike used an Italian Lenzi rear bag. Mike says the super-slick nylon on the ears of this high quality rear bag make for better tracking. The ears provide support but don’t “grab” the stock, reports Mike.
More Comments by Fellow Shooters:
“Truly an amazing feat. The 5X was the icing on the cake! Many shooters would be very happy with that group size at 200 yards.” — Mr. Zero
“Words cannot adequately express how many of us feel about your magnificent accomplishment at 1000 yards. Congratulations — that is terrific!” — Gene Beggs
“Truly amazing … well done on a great achievement… RESPECT!” — Elardus
“Bravo Mike pour ce tir incroyable. Ton exploit est sur le forum de tir longue distance en France bonne continuation.” — Frederic Riso
* There are two North American sanctioning bodies for 1000-Yard Benchrest, the IBS and the NBRSA. The previous 5-shot, 1000-yard IBS record is 1.397″ (50 score) by Tom Sarver in 2007. The existing NBRSA 1000-Yard 5-shot Light Gun record is 1.473″, shot by Bill Schrader in 2002.

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

Along with these popular cartridge types, DJ’s Brass can hydro-form 6 PPC, 30 PPC, 6 BRA, 30 BR, .260 AI, .284 Shehane and other wildcats.
Do you shoot a popular wildcat (such as the 6 BRA), but hate the hassle of fire-forming all your own cartridge brass? That 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 to your exact specifications for a reasonable cost.
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.

Darrell is a hydro-forming wizard who has perfected the process over the last couple of years. He has learned a few special techniques along the way to ensure uniform case-forming.
Without revealing any trade secrets, we can say the Darrell has very special dies and Darrell doesn’t use a mallet or hammer — he has a system that is much more consistent. Darrell tells us: “Many of my customers take this brass and load it ‘as is’ and go straight to a match and shoot some very nice groups.”
With Darrell’s hydro-forming service you don’t have to buy any special dies or other equipment. Darrell says: “Simply send me the brass you need or have it dropped-shipped to me along with a fired case that has not been sized. If you need formed brass for a new build (gun not yet fired), let me know and I will size the brass to fit within .001 of a PT&G GO gauge.”
Hydro-forming by Darrell costs $0.60 (sixty cents) per case with a minimum order of $60. Neck-turning is an additional $0.60 (sixty cents) per case (or $0.75 for magnums) plus actual return shipping. The turnaround is usually less than five days.
NOTE: After cases are hydro-formed by Darrell, every case is washed, cleaned and re-annealed. This cleaning and annealing process is included in the $0.60 (sixty cents) per case price — that’s all part of the Hydro-forming service.

Hydro-Forming Customer Reports
Here are testimonials from recent customers.
“Recently had Darrell Jones of DJ’s Brass Service hydro-form 6 BRX brass for me. The turn around time was very fast and the brass was to the exact specification I ask for. I actually shot the hydro-formed brass in a match [without further fire-forming]. It shot a 3.597″ — pretty amazing. Let DJ do the work for you!” — Mike Wilson (3 Time IBS Record Holder; 2013 and 2014 1000-yard IBS Shooter of the Year.)
“Darrell Jones of DJ’s Brass Service went far beyond the call of duty, to assist me [with my first] IBS match. I have had an interest in 1000-yard competition for many years and finally got the opportunity to try it. After researching the winning competitors, rifles, and rounds I ordered a Panda action with Krieger barrel in 6mm Dasher from Kelby’s. It was one week before the match and I had a rifle and no rounds. I contacted Darrell to hydraulically form 6mm Dasher from Lapua 6mm BR brass. He formed the brass and had it in the mail the next day[.] Since I have only reloaded for hunting or magazine fed rifles I was not familiar with proper seating to allow land engagement of the bullets for 1000-yard accuracy. Darrell took the time to advised me every step of the way to allow me to shoot a 3.158″ (5) shot group to win my first round of my first competitive match ever.” — Mike Youngblood

Do primer types make a significant difference in accuracy or vertical dispersion at long range? The answer is “maybe”. Here’s one anecdotal study that tracked vertical variance among six different primer types. The tester is a good shooter with a very accurate rifle — four of the six 4-shot groups were under 2″ at 500 yards. This test doesn’t settle the question, but does suggest that it may be worth trying a few different primer types with your match ammo.
Here is a very interesting test for the 6 BRA (6mmBR Ackley) cartridge. Forum member James Phillips, a talented long-range benchrest shooter, tested SIX different primer types from three different manufacturers. To help determine vertical dispersion, James set his target out at 500 yards. He then proceeded to shoot 4-shot groups, in order, with each primer type. Velocities were recorded with a chrono. The photo above shows the results. James says: “I’ll retest the best two for accuracy and consistency with 10 shots each”. CLICK HERE for full-screen target photo.
As you can see, ALL the groups are pretty impressive. The smallest groups, 1.253″, was shot with CCI 400 primers. Next best (and very close) was CCI BR4, at 1.275″ for four shots. The “flat line” winner was the Remington 7.5, at upper left. There was almost no vertical. If you are intrigued by this interesting primer test, you can join the discussion in this Primer Test FORUM THREAD.

CARTRIDGE: 6mmBR Ackley, aka 6 BRA. Parent case is 6mmBR Norma. The 6 BRA is fire-formed to create a 40-degree shoulder and less body taper. Capacity is increased, but the neck is longer than a 6mm Dasher. The capacity is enough to get to the 2950+ FPS accuracy node. Some shooters say the 6 BRA is more forgiving than the 6mm Dasher. The 6 BRA is certainly easier to fire-form.
TEST REPORT — Conditions, Shooting Method, Loading Method
Tester James Phillips posted this report in ourShooters’ Forum:
Conditions: The testing was done in the morning over flags. The flags never moved or even twitched. I had as perfect conditions as I could have asked for. It was overcast so no mirage and no wind. There were no other shooters, just me.
Test Procedure: Each shot was precisely shot at my pace and centered the best possible using my Nightforce 15-55X scope. I did not use the round-robin method. Each four-shot group with the same was shot at one time. Then I moved onto the next primer. Everything felt right for each and every shot fired today. Of course I could repeat the test tomorrow and it could be exact opposite of today’s test. We can chase this forever. But [soon] I’m going to test the BR4 and 400 primer… for best accuracy and consistency for 10 shots each.
How Rounds Were Loaded: Each load was weighed to one (1) kernel of powder. So I know that’s as good as I can weigh them. Each bullet seating force was within 1# on my 21st Century hydraulic arbor press.
Previous Initial Load Testing: All groups were shot with 31.1 grains of H4895. During initial load testing I settled in on the Sellier & Bellot primer to finalize everything as it showed more promise over the CCI 450 Magnum I also tried. I was actually surprised to have seen the higher ES and SD from that primer today along with the vertical shown. [Editor: Look carefully — one shot from the CCI 450 is right in the center black diamond, stretching the vertical. By contrast the Rem 7.5 had almost no vertical.]
Velocity and NODE Considerations: I was about 5-6 FPS above what appeared to been my optimum velocity of 2943-2945 FPS, so I’ll test 5 shots of 31.0 and 5 of 31.1 and see what happens from there. I can only assume my velocities where higher due to the higher humidity and of course temps were 5 degrees warmer this morning as well. It wasn’t far off but I noticed it.

Glenn worked up a trim-and-point recipe for this lot of bullets based on group size. Load development is all performed at 1000 yards using the group ladder method. Glenn’s record load ended up being 30.3 grains of H4985 powder with the 103gr bullet seated very far into the rifling with .005″ of neck tension. This gave a velocity of 3030 fps in the 28″ Krieger.
