You don’t hear much about PacNor barrels in long-range competition, but FORUM member Wes J (aka P1ZombieKiller), proved that they can shoot “lights-out” in a rig assembled by a talented gunsmith. A few seasons back, Wes decided to upgrade a 6mmBR for mid-range benchrest and varmint matches. Wes tells us: “Since I restocked my 6BR … I have not had a chance to shoot it much since I have been playing the 100-200 game. I decided to take it out and do some playing at 500 yards. I have to give some serious props to my buddy (and fellow FORUM member) ‘PREACHER’ who did the chambering and barrel work for me. He can certainly make a gun shoot good. The barrel is a PacNor 1:8″ twist. My load was 105gr Berger VLDs pushed by 29.6 grains of Varget.” The five-round, 500-yard group shot by Wes J with his 6BR, measured just 1.240″, as measured by OnTarget software. Now that’s one accurate rig!
Five by Five — 5-Shot Group at 500 Yards, 1.240″, 0.237 MOA
This Editor knows something about the potential of a PacNor barrel. I have a 3-groove stainless PacNor SuperMatch on a Savage-actioned 6BR. This barrel shoots honest quarter-MOA in calm conditions, and it cleans up super-easy. The interior finish is so good, I’ve never had to brush the bore or use abrasives, and after 750 rounds it shoots as well as ever. I attribute the easy cleaning to the fact the lands in a PacNor 3-groove are wide and flat, so they are gentle on bullet jackets. I think accuracy is helped by the fact that my PacNor runs on the tight side (0.236 land dimension) with a good amount of choke. That works well with the 105gr Lapua Scenars and 103gr Spencers I like to shoot. You can read more about my rifle, nick-named the “Poor Man’s Hammer”, in this Feature Article from our archives. On one particularly calm day, in the hands of my friend (and ace trigger-puller) Joe Friedrich, the Poor Mans’ Hammer put 3 shots in under 0.200″ (measured center to center) at TWO Hundred yards. If you get a good one, PacNor three-grooves can definitely shoot.
Target Measurement with OnTarget Software
We used OnTarget software to measure the 5-shot group in the target above. This easy-to-use software is very repeatable, once you get a feel for plotting the shots. The latest On Target v2.25 Precision Calculator is FREE for a 15-day evaluation period. If you like it (and you will, trust us) there’s a modest $11.99 registration fee to activate the program. In addition to group size (in inches), OnTarget plots distance to aiming point, and the software automatically calculates the group’s vertical height, horizontal dispersion, average to center (ATC), and group size in MOA.
You can run a measurement on a scanned target or a photo of a target. You’ll need some known reference to set the scale correctly. The target above had a one-inch grid so it was easy to set the scale. Once you’ve set the scale and selected bullet diameter and target distance, you simply position the small circles over each bullet hole and the OnTarget software calculates everything automatically, displaying the data in a data box superimposed over the target image. To learn more about OnTarget Software, read AccurateShooter.com’s OnTarget Product Review. This article covers all the basics as well as some advanced “power user” tips. NOTE: Since the review was written, On Target has updated the software, and the free version now has a time limit.

You can benefit from these precision mandrels, trust us…
Controlling cartridge neck tension is a critical aspect of accurate reloading. A very small change in the amount of grip on the bullet can actually have a noticeable effect on accuracy (and group size). You can tune neck tension with different size bushings used with FL-sizing or neck-sizing dies. You can also adjust neck “grip” by annealing your brass, or turning your necks for reduced neck-wall thickness.
But perhaps the most precise way to tune neck grip on the bullet is to use Precision Expander Mandrels. Many top shooters size their case necks down pretty far with a full-length sizing die then use a precision neck mandrel as a final step. This expands the neck back to the precisely-desired neck diameter. Because you are working from the “inside out”, variances in neck-wall thickness become less important. This also ensures you have a perfectly-round internal neck geometry for seating your bullet. (Yes, unfortunately some neck bushings are not perfectly round inside.)
For guys who want ultra-precise control over neck tension (and “grip” on the bullet), 21st Century Shooting now offers Precision Expander Mandrels in .0005 (one-half thousandth) increments. These will be available for most popular match calibers including: .224, 6mm, .25, 6.5mm, .270, 7mm, .308, and .338 calibers. These mandrels cost $17.99 each, or you can get a complete set of nine mandrels in .0005 increments (for one caliber) for $144.99. Listed below are the nine 6mm mandrels:
John Perkins, owner of 21st Century tells us: “Finally! We have our expander mandrels up and ready to order on our website here: http://www.xxicsi.com/expander-mandrels.html.” This is a big deal. James Crofts, past National F-TR Champion, says “WooHoo — great news!”
To get best results with these precision mandrels, John recommends using the 21st Century Expander Die Body, part #904. Watch video for set-up tips:
John adds: “We are still in the midst of turning all of these so some calibers will ship when they are completed. Should have them all done by end of next week or so! Thanks for your patience while we got these set up and in process!”

“Koenig” (or König) means “king” in German. That is indeed appropriate for Doug Koenig, 18-Time Bianchi Cup winner, who is now starting to conquer the rifle world as well. Koenig, considered by many to be the best action pistol shooter on the planet, proved he’s an ace with rifles too, as he recently won two PRS matches in Production Division. Koenig, Captain of Team Ruger, was shooting a Ruger Precision Rifle (RPR), chambered in 6mm Creedmoor. Notably, Production Division limits rifles to $2000.00 for the gun ($4000.00 overall with scope). You can buy an RPR for around $1100.00 typically ($795.00 at GrabAGun), so Koenig was shooting against competitors with rifles that cost nearly twice as much. That’s impressive.
Koenig Wins Production Class at two Spring PRS Matches
Koenig took home a pair of Production Division titles at this year’s WAR Rifles Shootout and MAP Spring Shootout Precision Rifle Series (PRS) matches.
With a final score of 128.00 and a time of 58.51, team captain Doug Koenig took first place in Production Division at the WAR Rifle Shootout PRS match in Mount Victoria, MD. The WAR Rifle Shootout has a challenging 22-stage course of fire. Along with winning Production Division, Koenig also finished twelfth overall. “The tough course of fire and 15-25 mph winds at the War Rifle match were brutal, but my Precision Rifle, equipped with a Leupold VX-3i LRP and loaded with Hornady ammunition, continued to perform,” said Koenig.
Koenig then secured another Production Division win at the MPA Spring Shootout held at the Arena Training Facility in Blakely, GA with a final score of 173.00 and a time of 58.89. “The MPA match had some long shots out to 800-1356 yards, but my factory rifle got the job done and helped me win my third production class title in a row. That proves you don’t need to spend a fortune to get started in PRS competition.”
According to PRS standards, Production Division rifles are not permitted to be altered or improved in any way from the original factory configuration, and the retail price may not exceed $2,000.
Pre-Fit Barrel Options for the Ruger Precision Rifle
While PRS Production Division competitors like Koenig must stick with factory barrels, there’s no law that says you can’t upgrade your own RPR that’s not used in PRS matches. A barrel swap is probably the single best hardware upgrade you can make. A new custom barrel will improve inherent accuracy and shot-to-shot consistency. Krieger Barrels offers Pre-Fit barrels for the RPR in many popular chamberings including 6XC, 6mm Creedmoor, .243 Win, 6.5 Creedmoor, 6.5 PRC, and .308 Win. These “Drop-In Ready” barrels come finish-chambered and threaded to fit the Ruger action, with factory-spec muzzle threads. The Ruger barrel attachment system allows correct headspace with a pre-chambered barrel. Krieger explains: “Thanks to Ruger’s proprietary barrel nut design, a competent gunsmith will be able to swap out your barrel using an AR15 barrel wrench and proper headspace gauges.”

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. Yes you can modify your own magazines (Mag Mod HERE), or buy a pricey conversion kit, but now there is a turn-key solution from MDT (Modular Driven Technologies).
MDT’s 6mm BR magazine fits the parent 6mmBR cartridge and all the popular varients 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.”
The MDT 6mm BR mag has a maximum internal length of 2.580″, which accommodates pretty much any 6mm bullet you’d want to use. These MDT magazines are crafted from quality steel, nitride-treated, then black Cerakote finished inside and out. To reduce friction between cartridge and magazine body, MDT added two internal ribs which provide a smooth transition from double stack to single-feed.
Magazine Conversion — Use .308 Win Mags with Modified Followers
A decade ago we showed our readers how to modify .308 Win magazines to feed the 6mmBR cartridge efficiently. This procedure, explained by Texas gunsmith, Mike Bryant, is easy to do with simple tools. You can modify most standard magazines, both internal-style and detachable style. CLICK HERE for full, step-by-step magazine conversion article.
The basic procedure involves trimming the rear of the magazine, and creating a rear stop with a block from a Remington .223 magazine. Next the .308 Win magazine follower is shortened and beveled. Some guys tweak the feed lips a bit, but this may not be needed. Many of our readers have performed this simple magazine modification and report their rifles feed quite reliably. One reader, who converted a 7mm-08 hunting rig into a 22 Dasher varmint rifle, tells us his modified mag feeds flawlessly.

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 ask 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.

Butch Lambert of ShadeTree Engineering provided this tip. Butch notes that many 6 PPC benchrest group shooters also enjoy shooting in score matches. But to be really competitive in the BR for score game, that means shooting a 30 BR, which has a wider, .308-class rim (0.4728″ diameter). Likewise, if you want to compete in 600-yard registered BR events or in varmint matches, you probably want to run a bigger case, such as the 6BR, 6BRA, 6mm Dasher, or 6-6.5×47. Those cartridges also have the larger 0.4728″ rims.
To convert a PPC-boltface action to shoot the bigger cases you can spend a ton of money and buy a new bolt. That can cost hundreds of dollars. The simpler solution is to turn down the diameter of the larger cases on a lathe. This is a relatively simple procedure with the right cutting tool.
Butch explains: “We’ve seen plenty of interest in rebating case rims. This lets you shoot a 30 BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle if you have a PPC boltface. Anyone who has access to a lathe can do this job pretty easily. Yesterday I turned 150 case in about an hour.” At right is the lathe form tool Butch uses to rebate the case rims.

What does it take to win in the tactical game? Ask Oregon’s Jon Pynch. He won the 2018 National Rifle League (NRL) 2018 Championship event along with three out of six of the bolt-action PRS matches in which he competed this year. And with 300 points overall this season, Jon has been a #1-rated shooter within the Precision Rifle Series (PRS). In most sports you’d call that an MVP performance.
PRS Competitor Jon Pynch had a superlative run in 2018, scoring victories in many big matches, capped off by winning top honors at the 2018 NRL Championship. And as you read this, this very day (December 2nd) Jon is shooting at the PRS Season Finale at the Triple C Range in Cresson, Texas. Here is Jon Pynch’s 2018 competition record:

Pynch won 3 out of 6 PRS bolt-action matches he shot in 2018. Pynch runs a landscaping business in Oregon. When time permits, he travels around the country to tactical matches. He grew up around guns, starting with his trusty BB gun, and the passion grew. About 14 years ago, Pynch started to dabble in long-range shooting from the hunting side. In the past few years, he has focused more on competition, observing how the sport has changed: “Over the past couple of years, I’ve noticed it feels like the level of competition and the level of quality products are growing at an incredible rate.”

The MPA BA Competition Chassis has many notable features: RAT System and multi-function Arca Swiss Rail provide a variety of bipod locations. There is a special rotating barricade stop, plus a spigot mount on the front of the fore-end which can extend the “wheelbase” between front and rear support. A clever Weight Tuning System allows competitors to adjust gun balance and reduce felt recoil.
State of the Art PRS/NRL Tactical Rifle:

John says: “On right (below) is unfired Lapua 6mmBR round. Shoot it and it turns in the case on the left. 6mm Dasher. 25 formed… 975 to go! Alamo Precision Rifles did a great job on this chamber/barrel. It’s won a few matches and placed well in a few others, but after 1800 rounds I think I’ll use the rest of its life as a practice/fireforming barrel.”

Have you ever expanded a .22 or 6mm cartridge all the way up to .30-caliber? If so, you know this can be a difficult procedure that stresses the case necks and neck-shoulder junction. A significant neck-size expansion done in one big jump can increase run-out, cause doughnuts, or worse yet, even split the brass. Therefore you want to proceed in increments, increasing the neck diameter in stages. One smart way to do that is to use a Progressive Press. This article explains how…
The most successful short-range brenchrest-for-score cartridge is the 30 BR. That cartridge, as well as 30 BR variants such as the 30 BRX, all start with the 6mmBR Norma parent cartridge, typically with Lapua 6mmBR brass. To get a nice 30 BR case you want to expand in stages, increasing the inside neck diameter incrementally from .243 to .308.
Darrell Jones of DJ’s Brass Service creates thousands of 30 BR cases each year. He has found a clever way to speed up the process — Darrell uses a Progressive Press. He runs his 6BR brass through four (4) separate Hornady neck-sizing dies with expander mandrels. First there is a .257 die, followed by .264 (6.5mm), .284 (7mm), and then .308. Then a fifth and final K&M die provides one last, slight expansion so the newly-fashioned 30 BR cases perfectly fit the arbor of Darrell’s neck-turning tool.
So to repeat, the case starts as .243 (6mm), then moves in up stages .257, .264, .284, and .308, with a final “finishing” step prior to neck-turning. You can see the expansion in this video, which starts with 6mmBR brass that was first hydro-formed to 6 BRX:
Watch 6mm Cases Expanded to 30-Caliber (6BRX to 30 BRX)
For this demo video, Darrell expands just one case at a time. However, he can also put multiple cases in the progressive — one per station. This takes a little more effort, Darrell says, but the results are still excellent. Darrell tells us: “I do put multiple cases in the progressive to save time. The results are the same — I just wanted to show a single-step process and how it reduces run-out by not stressing the shoulder with one big expansion from 6mm straight to 30 caliber. Doing the operation in multiple stages avoids binds and helps keep the shoulders concentric.”
This same multi-stage procedure can be use to expand other cartridge types. For example you could take .221 Fireball brass in stages up to .308 to create 300 Blackout brass.
Darrell uses caliber-specific, Hornady neck-sizing-only dies with elliptical expanders. Darrell tells us: “The Hornady elliptical expander has a reduced bearing surface that puts less strain on the brass when expanding the necks to the next size.” The fitting at the bottom of the die is the Lock-N-Load die bushing that allows fast die changes.
These particular cases used in the video were first hydro-formed to 6BRX then expanded to 30 BRX before neck turning. DJ’s Brass offers hydro-forming for many popular wildcat cartridges such as 6 PPC, 6mm Dasher, and .284 Shehane.

This story first ran two years ago, but we’re bringing it back to give you guys a smile this summer. Anyone interested in long range accuracy should enjoy this tale of an amazing 800-yard shot by a talented fellow nick-named “Junebug”…
If you were challenged to hit a quarter (i.e. a 25-cent piece) at 800 yards, how would you respond? Well here’s the story of a man who did take that challenge, and proceeded to put a bullet right through the quarter. Forum member Randy D., aka “Birdog”, provides this entertaining account of how his friend Junebug drilled a quarter at 800 yards one Tennessee evening….
Hitting a Quarter at 800 Yards
Story and photos by Birdog
A friend from Indy visited the DOME last summer and returned home telling stories of eggs at 800 yards. He called me back and said his friends did not believe it and wanted to know if I could hit a quarter out at 800 and mail it to him.
Well, I had finally got the time for that challenge last Sunday. My friend Junebug came over and I told him about a new challenge. Junebug is sort of like Voldoc and does not like to be told it can’t be done and set his sights on the quarter. George Clay had his sleeved 700 6XC with 115gr DTACs and Bug had his Diamondback 6 BRDX and 103gr Vapor Trail bullets.
Junebug and Shayne. The quarter was at back fence row on left of photo, 80 yards short of a half-mile
Early to mid-afternoon is not the time for precision 800-yard shooting as the mirage was terrible and the wind was gusting in the high humidity and 95 temps. We took a few shots and got close but no HIT.
I told Junebug to go home and load some shells and come back at 7:00 and I believed we could make it happen. After 7:00 pm is the best time to shoot as the mirage disappears and the wind goes to zero. We met again at 7:00 and had Shayne Halliburton as witness. I took a few shots then Junebug took a few zeroing shots on metal. He was not satisfied with the grouping so he switched brass.
He had some new Hydro-formed brass that had never been fired. He took three sighters on the metal plate and the first two made two little black spots that were touching. Followed with a third shot that almost touched the first two. Darkness was setting in and I told Bug he better try the quarter now. Through my March scope I could barely see the bright quarter and my 1/16th dot completely covered the quarter.
Junebug moved the Diamondback to the quarter and touched her off. A half second later the bright spot on the black paper was gone. I jumped up and did a dance and war hoop and the Bug jumped up for a high five. Now we hoped we could find the quarter. Luckily it jumped out in front of the backer less than five feet and Bug found it immediately.

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 1.068-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.
How small is that in angular measurement? Well 1 MOA at 1000 yards is 10.47 inches, so Mike’s 50-5X masterpiece is 0.102 MOA! Yes that will be pending IBS group size (and score) World Records. 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.
“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, 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, Bart Sauter, using a 6BRA, shot a 0.282″ 5-Shot group at 600 yards.” Bart’s stunning 0.04 MOA group is a pending 600-yard IBS World Record. (Read Sauter Story). Now Mike Wilson has a pending 1000-yard World Record with his 6BRAW.
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.
* 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.

Here’s something you’ve probably never seen before — a single-shot, bolt-action pistol chambered for the 6mm BR Norma cartridge. Featured as one of our Guns of the Week a while back, this Green Machine is a Savage Striker upgraded by Chuck G. from Arizona, a self-described “Savage Maniac”.
Chuck transformed this Savage Striker single-shot from a ho-hum .308 into a reliable half-MOA precision 6BR that can run with accurized rifles all the way out to impressively long ranges. Here we provide highlights from our original article. Click the link below to read our full Savage Striker article, which is three times longer than this story, and has more photos, plus videos and a detailed load development section.
The Striker Project — Pursuit of Precision, by Chuck G.
I didn’t even know Savage Strikers existed until I saw one for sale on Gunbroker.com. I snagged it with a $400 bid. My idea was to build an accurate, long-range pistol on a pauper’s budget. As purchased, the Striker had a .308 barrel with an unknown round count, the standard center-grip, black synthetic stock, an odd two-piece custom brake, and an old Burris 4X pistol scope in a Conetrol 2-piece ring set. The trigger was very heavy, 6-8 lbs I’d estimate, with a lot of take-up and over-travel.
Initial Disappointments — Too Much Recoil, Poor Accuracy
My initial attempts to get the Striker to shoot well at even 100 yards were disappointing. I was never able to get better than a 3″, 5-shot group at 100. Not what I was looking for. Being used to benchrest triggers, the pull on this one was hard for me to manage. The gun would roll around on any type of front rest I had, and from a cement bench on a bipod it would jump about 18 inches up and sideways with every round. Not being used to this type of gun, I found the recoil and muzzle blast to be unsettling. It was hard not to flinch. I started off using my 1K .308 rifle load, 175 SMKs over 44 grains of Varget. That probably would have knocked the hell out of a deer, but it wasn’t much fun to shoot from the bench.
New Caliber, New Barrel — Way Better Accuracy!
I decided to rebuild the Striker in a caliber that would be more fun to shoot. 6mmBR was an obvious choice for all the usual reasons–good brass, wide choice of match bullets, easy to load, low recoil, very accurate, and relatively cheap to shoot. As part of a SavageShooters.com group buy, I ordered a 15″, SS match grade, 3-groove, heavy varmint contour, 10-twist barrel from Pac-Nor. To set the freebore, I provided Pac-Nor with a dummy case with an 88gr LD Berger bullet seated to use as a guide. Total delivered price was $340 chambered and threaded for a muzzle brake from JP Rifles.
When I bought it, the Striker, with factory .308 barrel, shot 3″ groups at 100. Now, with a Pac-Nor 6BR Match barrel, 3″ fore-arm plate, upgraded trigger, 24X scope, and match bullets, the gun consistently groups 1/2″ or better at 100 yards. What a transformation!”
Striker Project — Mission Accomplished
With further load development and bench practice, the gun is showing even more accuracy potential. Using a 24X target scope, the Striker has delivered 5-shot groups in the 3s and 4s during recent range visits. All in all, I’m very satisfied with the project. I ended up with an accurate, fun-to-shoot gun for under $1,000 including scope, paint, and bedding materials.
Stock Modifications
While waiting for the barrel I started working on the stock. As virtually no aftermarket stocks were readily available for the center-grip Striker, I decided to rebuild the standard black synthetic stock. The grip fit my hand poorly so I worked it over with a Dremel tool and sandpaper, built up the grip with Bondo, filled in some holes and bedded the action using Devcon Plastic Steel. This was my very first attempt at these tasks so progress was slow. Once I had re-shaped the stock, I sprayed five coats of “John Deere” green topped by several coats of auto clear. It came out surprisingly well considering I had never painted a stock before. I had originally planned to build up the fore-end to 3″ wide using Bondo but later decided to just use a Sinclair Benchrest Adapter that I had on hand.
Chuck notes: “I’m really pleased with the C & J one-piece Rest. It’s solid, heavy, and well-designed. There is no real need for a windage top; small adjustments are easily made by slightly shifting the pistol butt. Elevation adjustments are positive and once the pistol is set up on this rest NOTHING moves.”
Target Measurement with OnTarget Software
If you haven’t tried Lapua bullets yet you should. The Scenar-L bullets we have tested have proven extremely consistent in weight and base-to-ogive measurement.
