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.

Shown are funnel with ultra-long drop tube (which helps get more kernels in the cases), RCBS Chargemaster (in wood box), and Hood Press (similar to Harrell’s Combo press).
Loading at the range remains important in the Benchrest for Group discipline. In a Special Report below, past IBS President Jeff Stover explains how loading methods (and hardware) have evolved over the years. The advent of accurate, affordable electronic powder dispensers, such as the RCBS ChargeMaster and Frankford’s new Intellidropper, have changed the game and made it easier to load efficiently at the range. And quality manual powder measures are fast and can be very consistent, with a little practice. Loading at the range permits competitors to tune their load to the conditions, change seating depths, or even choose different bullets to suit the barrel’s preferences on any given day.
Although pre-loading is not uncommon, most 100/200-yard group shooters usually load at the match, often between relays. The goal is to shoot smaller groups by staying “in tune”. In a game where 5-shot groups “in the 1s and Zeros” is the goal, tuning loads for the conditions helps deliver match-winning accuracy. Nearly all competitors in this short-range discipline shoot the 6mm PPC cartridge, or a PPC variant.
Loading at the Range — Then and Now
In benchrest shooting for group, loading at the range has been de rigueur for decades. In the Score discipline, preloading is usually the custom. The main reason is that, in Score competition, only one Aggregate (warm-up match and five record targets) per day is usually shot. That would be less than 50 shots, assuming a few sighter shots. Also, the 30BR, the dominant Benchrest-for-Score cartridge, is very amenable to pre-loading.
By contrast, the Group discipline includes 21 targets (two warm-ups and twenty record targets) over a weekend, usually shot with 6PPC-chambered rifles. Many times, the 6PPC shooters may tweak their loads through the day given changing atmospheric conditions or simply trying to find the correct tune to “dot up”. This term, “Dot up”, means the shots are essentially going through the same hole, or closely so.
Loading at the range was a bit different when benchrest competition was in its infancy. The 1951 book, Modern Accuracy by Bob Wallack, is the best of the early benchrest books. Copies can be found, from time to time, on eBay or Alibris. It is a fascinating survey of benchrest as it existed more than six decades ago. There’s even coverage of a controversial target that was argued over at the time. In it, there is a photo of Wallack using the rear bumper of a car at the bench to clamp his reloading tools. Things have come a long way compared to the range loading set-ups of modern shooters. Here you can see Bob Wallack way back in 1950:
Modern loading bench set-ups shown in this Special Report belong to top shooters Howie Levy, Bob Hamister, and Kent Harshman.

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

Check out those five targets. The Aggregate (average) of all five targets is a tiny 0.0840 inches! These were shot by Gary Ocock at 100 yards in a California benchrest match on August 6, 2017. Though Gary’s 0.0840 Agg beats existing records, this was not a “sanctioned” match, so Gary’s killer Agg was NOT submitted for IBS or NBRSA records. So, sadly, the Agg won’t appear in the record books, but this remains a spectacular, verified feat of rifle accuracy, accomplished in competition.
Gary’s red railgun is arguably the Most Accurate Gun Ever Built. As far as we can determine, no one has ever shot a smaller 5-target Agg anywhere, at any time. FYI, the NBRSA Unlimited Class 5×5 Aggregate World Record is 0.1242″ shot by Jerry Lahr in 2012. Gary’s 0.0840″ Agg is much smaller.
The Unlimited Benchrest Record That Will Never Be (Official)
Report by Boyd Allen
Gary Ocock’s stunning unlimited Aggregate is beyond amazing. That’s an average of five, 5-shot groups of .0840. Shot under sanctioned match rules, but at an unsanctioned 100-yard fun match, this Aggregate is well under the current 100-yard official records of the IBS (.1386), and the NBRSA (.1242). The fourth of the five groups measured a minuscule .018, less than half the size of the existing NBRSA Unlimited record of .049 (also shot by Gary). Check it out:
When the top 15 shooters all post teen Aggs, conditions must be pretty favorable. However there were some light switchy winds — Gary said that he shot better in the left to right condition.
GUN SPECIFICATIONS
Ocock’s red Jay Young Unlimited Railgun features one major difference from Young’s typical Railgun designs. The bottom of the barrel block is integral with the top (moving part), of the gun. The barrel is Ocock’s usual 1:13.5″-twist Krieger chambered for the 6 PPC. The BAT Neuvo action* is unusual in that its lugs are horizontal at lock-up instead of the usual vertical. With horizontal lugs, both lugs maintain contact with their abutments when the action is cocked. In the more normal configuration when cocked the top lug is forced off of its seat by a combination of the angle of the trigger cocking piece interface, the pressure of the striker spring, and bolt clearance at the rear of the action.
LOAD SPECIFICATIONS
Gary shot this remarkable Agg with well-used brass, Vihtavuori N133 powder, and self-made 66gr BT bullets** seated at “jam”. This amazing Agg was shot on the second day of a 2-day Unlimited Benchrest match. On Day 1 Gary had experimented with various loads using both surplus IMR 8208 and Vihtavuori N133, but was not satisfied with the results. For his first group on Day 2, Gary tried a light load of N133. After seeing the result, however, he decided to go to the other extreme — a super stout N133 load — with the same powder. As you can see, Gary’s willingness to experiment paid off.
Notably, Gary used light neck tension. Ocock found that for these bullets and this barrel, light neck tension worked best (contrary to “normal” N133 benchrest practice). Ocock used a bushing that only produces .001″ difference between the diameters of sized and loaded case necks.
This video shows a line-up of Rail-Guns. One of Gary Ocock’s Rails appears at the 0:35 time-mark.
Comment on Ocock’s Achievement
Congratulations to Gary Ocock for superb shooting (and smart loading). Even though the match was not sanctioned (so the Agg will never be a record), Ocock has raised the bar very high, and given us a new standard of ultimate accuracy.
Though this 0.0840 Aggregate and 0.018 group will never go into the record group, they are still noteworthy. There’s virtually no doubt that they would have survived inspection by any record committee. Except for the lack of fixed backers, an IBS requirement (for detecting cross-fires), all other conditions were met for an officially-sanctioned match.

Here is Gary with his Red Railgun at a Visalia event in October 2017. Ocock let the event’s youngest competitor, 12-year-old Gavin Lichtenwalter, shoot Gary’s new Railgun for the last three matches on Sunday afternoon. The day before, 10/21/17, Gary shot an IBS Heavy Benchrest World Record putting five shots in just 0.045 inches, as certified by the IBS record committee. Here is that group, as first measured at the range at 0.039 inches. Gary also holds the Unlimited 5-Shot NBRSA 100-Yard Record with an 0.049 inch single group shot on 10/17/2009.
*The new BAT Neuvo actions are the result of a collaboration between Dwight Scott, and Bruce Thom, featuring Dwight’s ideas and BAT’s proven manufacturing expertise.
** Ocock shot his own, boat-tail match bullets, made with George Ulrich-crafted dies using Hood cores. Although he said that it had been a while since he had weighed any, his best guess was that they weigh something around 66.5 grains.

Think you need a relatively long case-neck for good accuracy? Think again. Stan Ware broke all the rules with his radical Wolfpup cartridge, proving that a near-no-neck design can deliver match-winning accuracy. Read on to learn how the Wolfpup works…
Retired gunsmith Stan Ware is a talented shooter who’s not afraid to think “outside the box”. Stan competes in both Hunter Benchrest (HBR) and Varmint for Score (VFS) disciplines. In his quest to build the ultimate Hunter Benchrest cartridge, Stan created the radical “Wolfpup” wildcat, based on a 6mmBR parent case. Noting the dominance of 30 BRs in VFS matches, Stan wondered if a stretched 30 BR could work in HBR competition. The challenge was case capacity. Under HBR rules the cartridge must hold at least 45.0 grains of water, equal to the capacity of the classic 30/30 case.
To get the requisite HBR case capacity, Stan figured he needed to boost the volume of a 30 BR case significantly, so he would have to move the shoulder forward — a lot. He did this by running a 30 BR reamer deeper and deeper, test-firing brass along the way. After three reamer passes, he ended up with the capacity he needed (the Wolfpup holds 45.3 grains of water). But then he looked at the finished product — a case with almost no neck, and he wondered “how could this possibly work?”.
From Trashbin to Winner’s Circle
Ware’s prototype Wolfpup ended up so short-necked, so unlike any “normal” cartridge, that Stan figured it was “dead on arrival”. Stan told us: “I said ‘this ain’t going to work’ and I threw the brass in the trash can. Honest. But later I thought I better shoot it and see what it does.” There was one problem — Stan didn’t have a seating die. He noticed the short neck provided a bit of tension after fire-forming, so he literally seated some bullets, BIB 118s and 125s, with his fingers. For powder he used H4198 and started with 35 grains, one grain more than a 30 BR load. Stan then did a pressure work-up: “I actually went up to 41.0 grains and didn’t have a sticky bolt. I ended up at 37.9 grains of Hodgdon 4198 — that gave 3150 fps, where the sweet spot is.” (Later testing revealed a second accuracy node at about 3020 fps, using 36.4 grains of H4198).
Stan’s radical short-necked Wolfpup shot great from the get-go. Once he found the right velocity node, the gun shot in the ones and zeros with both 7-ogive and 10-ogive bullets, both 118s and 125s. The Wolfpup proved easy to tune — it’s not finicky at all. And it’s a winner. Stan began shooting the Wolfpup in 2006 in both VFS and HBR matches and the ‘Pup’ started winning matches right away. In 2007, Stan won the Wisconsin State VFS Championship shooting the Wolfpup. In June 2010 at a Webster City, Iowa VFS match, Stan won the Grand Agg and posted high X-Count for the match, while placing first at 100 yards and second at 200 yards. How’s that for a cartridge that almost ended up in the trash bin?
Does Stan deserve an award for “most innovative benchrest cartridge design”? Stan chuckles at that notion: “I’m not a hero, not a genius. I really didn’t do anything. The fun part is thinking outside the box — for me anyway. Shooting is an age-old process of experimentation. You never learn it all.”
Why Does It Work?
How can such a radical case design perform so well? “That’s a good question,” Stan admitted. He then explained: “The 30 BR is inherently accurate, so I figured something based on the 30 BR should be accurate too. My personal belief is that the short neck doesn’t hurt you. Plus if the throat in the barrel is straight, the bullet can self-align. If the chamber is good, the bullet will self-center in the throat. In a regular case there’s not much room to do that, so a bullet can start off-center, and you don’t get the same results every time. A bullet in a conventional case is stopped from self-centering by the stiffer neck, particularly in a tight-clearance BR gun.”
Reloading the .30 Wolfpup
Stan’s Wolfpup chamber has a neck dimension of 0.330″. He turns his necks for a 0.327″ loaded round. Bullets are jammed .020″ forward of first contact with the lands. When he closes the bolt it pushes the bullet back in the case — almost a soft seat. Stan notes: “To start with I normally bump the shoulder .0005-.001″ so they go in easy. Just by doing that I get a little neck tension. I also use a bushing. Right now I’m running a .322, but it’s not particularly sensitive. I’ve tried one-thousandths increments up to a .325 bushing and couldn’t tell a lot of difference.” For bullet seating, Stan uses a Wilson 30 BR seater die into which he ran the chamber reamer. This gives perfect case fit during seating operations.
About the Illustrated Gunstock
You’ll notice Stan’s stock contains scenes from Vietnam and a quotation. Here’s the story. A Vietnam combat veteran, Stan served “in-country” with the Army’s 509th Non-Divisional Combat Unit (out of Fort Riley) from 1965-1966. Shortly before he left Vietnam, Stan went to a shop to have a souvenir lighter engraved. He asked the vendor for an appropriate inscription. The shop’s metal-worker engraved: “War is a tragedy. It takes mans’ best to do mans’ worst.” That message, along with the combat scenes, were hand-painted on Stan’s rifle by his wife Susan, a talented artist. She spent more than 20 hours painting the rifle stock.

Hardware Choices: Actions, Stocks, Barrels, Optics and More Tech Talk by Jeff Stover
This article was prepared by past IBS President Jeff Stover based on results from the 2019 IBS 100/200 Group Nationals held August 12-17, 2019 at the Holton Gun & Bow Club in western Michigan.
Let’s examine the Top Ten rifles from the IBS Group Nationals in the 10.5-lb Light Varmint Class. We’ll focus on the most popular rifle components — the choices for Actions, Stocks, Barrels, and Scopes.
Hall of Famer Jeff Gaidos taking aim at the 2018 IBS Group Nationals. He has a low-profile carbon-fiber stock with a Leupold fixed-power scope.
For some years now, BAT has been the predominant action. This year BAT actions held nearly 100% of the Top Ten places in all the Bag Gun equipment lists. Bruce Thom’s Idaho-crafted actions, except for a couple stray actions in Heavy Bench, swept the top rankings.
Next, look at barrels. Bartlein or Krieger seem to rule with upstate New York’s venerable Hart barrels as competitive. Shooters tend to go with winners, so Wayne Campbell and Jeff Peinhardt dominate as gunsmiths for the top benchrest shooters.
In stocks there seems to be variety, but there is some commonality. The Scoville and Scarbrough stocks, both Michigan-made, are laminated wood (balsa and other wood) with carbon fiber and wrapped in carbon fiber. The Scoville stock on my 10.5-lb rifle weighs 18 ounces but is full size with a nice long fore-end. Bob Scarbrough makes a very similar product. Both are winners — it’s a choice of Ferrari or Lamborghini. The Roy Hunter and Terry Leonard stocks among these top rifles take a different route to winner’s circle. Both are wood (cedar or other), but super high-tech as they are laminated with carbon fiber. They are beautiful to boot. High-magnification Leupold, March, and Nightforce scopes rule the roost among benchrest optics.
Bullets and Powder
Bullets are important. Really important. A hot bullet gives you “Teen Aggs” and lots of trophies. An average bullet does not. Most of these are 68 grain 6mm boattails. The Peinhardt (StaMoly Precision) bullet is well represented on this list, but some top shooters make their own as you can see. Bullet jackets are likely StaMoly or J4. For powder, nearly everyone shoots Vihtavouri N133 except a few guys running LT30/32 or surplus 8208.

Modern long-range benchrest rifles are capable of remarkable accuracy. At the recent Rendezvous Match at the Vapor Trail Valley shooting club, some exceptional targets were shot. This is a special combined match with relays at both 600 and 1000 yards. Be amazed at the accuracy modern rifles can achieve at these distances. Match director Tom Jacobs reports: “We had two screamer groups under a inch at 600 yards, and six groups under 3″ at 1000 yards. Three of those were under 2.5″ screamers.”
New Range Record at 1000 Yards — 1.338″ 5-Shot Group
Dave Way set a new Vapor Trail 1000-yard Range Record for single 5-shot group. He had a wicked small 1.338″ group (0.128 MOA) with a 49 score.
New Single Target Small Group Record at 600 Yards — 0.645 (0.103 MOA)
At the Rendezvous, Jason Cohen set a new single-target small group range record at 600 yards. This was a 0.645″ group shot with a .284. That works out to 0.103 MOA (1 MOA is 6.282″ at 600 yards).
Multiple Agg and Overall Titles for Al Benarrock — and a $1500.00 Check
Al Benarroch had a phenomenal weekend. He won the 16 target 600yd/1000yd Ultimate Agg (Grand Overall), the 1000-yard 8-target group Agg with 4.953″, and the 1000-yard 8 target Overall. What a weekend for Al!
The match was a big success. Match director Tom Jacobs posted: “We had great weather at a match for once, temps were mild for us this time of the year, the winds were not bad at all but we did have quick switches, that the valley is known for. Mirage was bad at times, but no dam hurricanadors for once! We hung 778 targets down range, not including all the tuning targets throughout the week. We estimate 9336 rounds went down range for the match, not counting a week of guys tuning.”

What’s better than a super-accurate 6BR rifle? Well, two super-accurate 6BRs. This week we feature a pair of tack-drivers owned Forum member Mark Schronce. These “Brothers in Arms” share similar stocks, but otherwise the components are different. Mark’s 17-lb gray laminate Light Gun features a Hall action, HV taper barrel, and muzzle brake. The 21-lb Heavy Gun, in “Desert Camo” laminate, boasts a trick dual-port BAT action, and full-contour 30″ barrel without brake. Both guns shoot tiny groups, track like they’re on rails, and give Mark a serious hardware advantage in club competition.
Mark provides this report: “The Light Gun started as my 22-250 AI varmint gun, with a Hall action and McMillan Hunter Benchrest stock. I wanted to build a proper Egg Shoot gun, so I had Richard Franklin (Richard’s Custom Rifles) chamber a Lilja 12-twist in 6mm BR Norma, with a .262″ neck. Using Fowler 80gr FB bullets, the gun shot great right out of the gate. (See my report, Egg Shoots and 600-yard 6 BR). I was curious about the heavier 6mm bullets, so I had Richard chamber and fit a 1:8″ Krieger in 6BR. But this time we went with a .271″ no-turn neck. The Krieger holds quarter-MOA with the heavy bullets, and, to my surprise, it shot the 80s as well as the 12-twist Lilja did. For the 2005 season, I ordered one of Richard’s latest 008 F-Class stocks. This new design is very comfortable to shoot and it’s much more stable in the bags than my old Hunter stock. That added stability will be a big plus for 600- and 1000-yard benchrest matches.
A Heavy Gun for 1000-yard BR and “Belly Benchrest” (F-Class)
I’ve been active in 1000-yard Benchrest for a few years, shooting my 6mm BS and 6mm BR Light gun in both Light and Heavy classes. I wanted to build a rifle for the Heavy Gun Class yet stay within the 22-lb F-Class limit. And I wanted it to have the best hardware I could buy. On a BAT ‘MB’ action (with Jewell trigger) we fitted a 30″ 8-twist 3-groove Lilja, 1.250″ diameter, no muzzle brake. Richard cut the chamber for 6mm BR Lapua Brass, .271″ no-turn neck, throated for Sierra 107gr MKs, matching my current Light Gun. The stock is a pillar-bedded Richard’s 008 1000-yd/F-Class model, with 10 coats of auto clearcoat, all work by Richard. Burris Zee rings hold a Leupold 8.5-25×50 LRT mounted on a BAT one-piece Weaver base. The Heavy Gun weighs in at 21 lbs, much lighter than most Heavy Guns (50 to 100 lbs). But with the 6BR’s light recoil, it’ll do just fine for long range, yet still make weight for F-Class.
Why a 6mm BR Chambering in a Heavy Gun?
I toyed with the idea of going with a 6BR Improved for Heavy Gun, but I’m not convinced the Improveds are worth the extra hassle of fire-forming, not to mention the added cost of custom dies. By way of background, I used to have a Rem-actioned rifle chambered in 6BR BS (Bill Shehane), which is very similar to the 6BR Dasher. I found the 6BR BS was only about 100 fps faster than a standard 6BR. For the shooting I do, that extra 100 fps is not critical. If, in the future, I feel I need more speed, I will go to a .243 AI or a 6.5-284. To be honest, I love the 6BR cartridge. Barrels last forever, and the accuracy can’t be beat. Yes a 6BR is a little light for everyday 1000-yard shooting, but on good days it can set world records. I may move up to a 6.5-284 some day, but for now I will stay with the standard 6mm BR. If I ever do want to go to a bigger caliber, the 8.5-inch BAT Machine MB action gives me this option.
Hall vs. BAT Light vs. Heavy
Comparing the two actions’ bolt lift, lock-up, fit, and finish, I feel they are equally good. However, the BAT can run stout loads with Federal 205 primers — loads that cratered Fed 205s with the Hall. I don’t know if this is a function of the actions’ engineering, or the barrels. I’ve got a Lilja on the BAT, while the Hall wears a Krieger. I do know the BAT has a tight-fitting firing pin, and that might make a difference.
Both my actions have a built-in recoil lug — a really nice feature when you are changing barrels, and one of the main reasons I favor custom actions over a Remington. I think anyone would be pleased with either the BAT or the Hall.
There is a big difference in shooting a Light Gun vs. a Heavy Gun, as you might expect. The Heavy Gun is more stable and recoils straight back. However, even at 21 pounds, the Heavy Gun actually recoils harder into your shoulder than the muzzle brake-equipped Light Gun. But if you take the Light Gun’s brake off, and put the action back in the old Hunter bench stock, the gun would jump, torque and roll. It’s much better with the 008 stock now, but still not as rock solid as the Heavy Gun. On recoil the 21-pounder just tracks straight back, no jumping, no yaw, no rolling–very impressive.
Load Development and Accuracy Results
Developed last year, my favorite Light Gun load is 30.5 grains Varget, CCI BR4 primers, and 106gr Clinch River VLDs, running 2825 fps. The Light Gun shoots other bullets very well, but the Clinch Rivers performed best, with groups in the 0.1s to the low 0.2s at 100 yds. I use Lapua brass of course.
I began my load development for the Heavy Gun with components I had from last year: Varget, N140, and N540 powders, plus Fed 205, CCI BR4, and CCI 450 primers. I also had a good selection of bullets: 95gr and 105gr Bergers, 105gr Lapua Scenars, 106gr Clinch Rivers, and 107gr Sierra MKs.
The Heavy Gun liked the Bergers right from the start. During break-in and fire-forming (with 95gr Bergers 0.20” into the lands, 30.0gr Varget and CCI 450s), the rifle shot in the low 0.2s at 100 yds, 0.3s at 200 yds, with a 0.182″ small group at 200 yards (see photo). I then moved up to the heavier bullets and again the Bergers stole the show. Best load for the Berger 105s (seated 0.15″ into the lands) was 30.5 grains Varget and Fed 205s at 2850 fps. At 100 yards, this recipe shot in the 0.1s to the low 0.2s with a small group of 0.089″. (By the way, this same load in my Hall Light Gun would crater the Fed 205 primers. I may have to change to CCI BR4 primers for the hot summer days.) After working with the 105s I wanted to see how the Heavy Gun performed with lighter bullets. I tried my favorite Egg Shoot and 600-yard load–80gr Fowlers pushed by 31.5 grains of Vihtavuori N135 with Fed 205 primers. The results were fantastic. The big BAT produced a 100-yard aggregate (five, 5-shot groups) in the 0.2s with an 0.129″ small group. Overall, at 200 yards, both guns could agg five 5-shot groups in the 0.3s and 0.4s. Eggs Beware!
Big, Strong, and Versatile ‘MB’ Action by BAT Machine
I looked at all the custom actions, and decided on a BAT model ‘MB’, configured Right Bolt, Left Port, Right Eject. The ‘MB’ action has some pretty unique features, including an integral recoil lug on the underside, and a recessed tenon (i.e. the threads start 1″ from the front of the receiver). The action is 8.5″ long, but with a 7.5″ bolt. The extra inch is added to the front. That provides extra bedding surface and room for a third pillar. The 8.5″ action length gives me the option to go up to a 6.5-284, while the dual ports should help give me the speed I need for the 10-round strings in Heavy Class. Also I can load from either side for F-Class.
Why did I choose a BAT? First, BAT quality is second to none. Moreover, BAT will custom-configure your port(s) and bolt for the same price, no added fees. Other action-makers charge extra for anything other than your basic Right Bolt, Right Port. This makes the BAT about the same price as a Stolle or Nesika, if you want a set-up like mine. The right-side ejection port is slightly smaller than the left feed port, but I can still feed 6BR cases from either side if I wish. The MB action is so big, the little BR case runs out of ejector as soon as the case leaves the chamber, so I push the case out to the right as I load the next round from the left. The BAT will eject a loaded 6BR round just fine, but a fired case only ejects sometimes. This action would work great with a longer round, such as a .243 AI or 6.5-284. If you want completely reliable 6BR ejection, you’ll need a smaller BAT action. But then, like my Hall standard action, the port would be too small for a 6.5-284.
Richard’s #008 Stock — How it Handles
The 008 stock is the best design I’ve ever shot off the bench. I like to hold my guns, and the 008’s grip profile gives me the control I like. The trigger is close enough for my short fingers. The underside of the buttstock is flat and completely straight (parallel to the barrel), so the gun tracks straight back. During recoil, the scope stays on target, making for quicker recovery time. In the picture at left, you can see that the underside of the fore-arm is relieved in the middle with raised strips on the left and right. These “rails” make for less surface area contacting the bags, less friction, and more consistent recoil. The high comb on the stock allows better prone shooting. For now, the stock is fine for what prone shooting I do. But if I do get seriously into into F-class I may want to add an adjustable comb or cheekpad. We’ll see.
Plans for Competition — The Lure of Hickory Groundhog Shoot Dollars
Some years ago, after building this pair of accurate 6mmBR rifles, Mark Schronce told us: “I can’t wait to see how this pair perform at long range. I will also take the Light Gun to the big Hickory GroundHog match in April, but I may put the barreled action back in the Hunter stock. This year you have to use bipods or sand bags, no front rest. [Editor: that is no longer the rule.] I don’t know if want to drill into my pretty new 008 stock for a bipod mount. I’ll let you know how it goes, and hopefully I’ll come back with some loot from the Shoot.” NOTE — that year Hickory offered about $8000 worth of prizes.

Here are five targets, each with FIVE shots in essentially one hole. This amazing feat of accuracy was accomplished six years ago. We are reprising our report because this five-target Aggregate arguably represents the most impressive feat of 100-yard accuracy in the history of marksmanship on this planet.
Check out those five targets. The Aggregate (average) of all five targets is a tiny 0.0840 inches! These were shot by Gary Ocock at 100 yards in a California benchrest match on August 6, 2017. Though Gary’s amazing 0.0840 Five-Target Agg beats existing records, this was not a “sanctioned” match, so Gary’s killer Agg will NOT be submitted for IBS or NBRSA records. So, sadly, the Agg won’t appear in the record books, but this remains a spectacular, verified feat of rifle accuracy, accomplished in competition.
The argument can be made that this is the Most Accurate Gun Ever Built. As far as we can determine, no one has ever shot a smaller 5-target Agg anywhere, at any time.
The Unlimited Benchrest Record That Will Never Be (Official)
Report by Boyd Allen
Gary Ocock’s stunning unlimited Aggregate is beyond amazing. That’s an average of five, 5-shot groups of .0840. Shot under sanctioned match rules, but at an unsanctioned 100-yard fun match, this Aggregate is well under the current 100-yard official records of the IBS (.1386), and the NBRSA (.1242). The fourth of the five groups measured a minuscule .018, less than half the size of the existing NBRSA Unlimited record of .049 (also shot by Gary). Check it out:
When the top 15 shooters all post teen Aggs, conditions must be pretty favorable. However there were some light switchy winds — Gary said that he shot better in the left to right condition.
GUN SPECIFICATIONS
Ocock’s red Jay Young Unlimited Railgun features one major difference from Young’s typical Railgun designs. The bottom of the barrel block is integral with the top (moving part), of the gun. The barrel is Ocock’s usual 1:13.5″-twist Krieger chambered for the 6 PPC. The BAT Neuvo action is unusual in that its lugs are horizontal at lock-up instead of the usual vertical. With horizontal lugs, both lugs maintain contact with their abutments when the action is cocked. In the more normal configuration when cocked the top lug is forced off of its seat by a combination of the angle of the trigger cocking piece interface, the pressure of the striker spring, and bolt clearance at the rear of the action.
LOAD SPECIFICATIONS
Gary shot this remarkable Agg with well-used brass, Vihtavuori N133 powder, and self-made 66gr BT bullets* seated at “jam”. This amazing Agg was shot on the second day of a 2-day Unlimited Benchrest match. On Day 1 Gary had experimented with various loads using both surplus IMR 8208 and Vihtavuori N133, but was not satisfied with the results. For his first group on Day 2, Gary tried a light load of N133. After seeing the result, however, he decided to go to the other extreme — a super stout N133 load — with the same powder. As you can see, Gary’s willingness to experiment paid off.
Notably, Gary used light neck tension. Ocock found that for these bullets and this barrel, light neck tension worked best (contrary to “normal” N133 benchrest practice). Ocock used a bushing that only produces .001″ difference between the diameters of sized and loaded case necks.
Comment on Ocock’s Achievement
Congratulations to Gary Ocock for superb shooting (and smart loading). Even though the match was not sanctioned (so the Agg will never be a record), Ocock has raised the bar very high, and given us a new standard of ultimate accuracy.
Though this 0.0840 Aggregate and 0.018 group will never go into the record group, they are still noteworthy. There’s virtually no doubt that they would have survived inspection by any record committee. Except for the lack of fixed backers, an IBS requirement (for detecting cross-fires), all other conditions were met for an officially-sanctioned match.
Boyd Allen notes: The reason that the match was not sanctioned was that the sanctioning bodies like to have a month’s notice when scheduling a sanctioned match and because the range had been down for modifications and this was the first match after that, there was some question as to whether the work required to have stationary backers could be finished in time for the match. Rather than promise what might not be deliverable, the decision was made to hold the match under all of the usual competition rules as a non-sanctioned “fun” match. None of this diminishes Gary’s performance.
* Gary Ocock shot his own, boat-tail match bullets, made with George Ulrich-crafted dies using Hood cores. Although he said that it had been a while since he had weighed any, his best guess was that they weigh something around 66.5 grains.

Hardware Choices: Actions, Stocks, Barrels, Optics and More Tech Talk by Jeff Stover
This article was prepared by past IBS President Jeff Stover based on results from the 2019 IBS 100/200 Group Nationals held August 12-17, 2019 at the Holton Gun & Bow Club in western Michigan.
Let’s examine the Top Ten rifles from the 2019 IBS Group Nationals in the 10.5-lb Light Varmint Class. We’ll focus on the most popular rifle components — the choices for Actions, Stocks, Barrels, and Scopes.
Hall of Famer Jeff Gaidos taking aim at the 2018 IBS Group Nationals. He has a low-profile carbon-fiber stock with a Leupold fixed-power scope.
For some years now, BAT has been the predominant action. This year BAT actions held nearly 100% of the Top Ten places in all the Bag Gun equipment lists. Bruce Thom’s Idaho-crafted actions, except for a couple stray actions in Heavy Bench, swept the top rankings.
Next, look at barrels. Bartlein or Krieger seem to rule with upstate New York’s venerable Hart barrels as competitive. Shooters tend to go with winners, so Wayne Campbell and Jeff Peinhardt dominate as gunsmiths for the top benchrest shooters.
In stocks there seems to be variety, but there is some commonality. The Scoville and Scarbrough stocks, both Michigan-made, are laminated wood (balsa and other wood) with carbon fiber and wrapped in carbon fiber. The Scoville stock on my 10.5-lb rifle weighs 18 ounces but is full size with a nice long fore-end. Bob Scarbrough makes a very similar product. Both are winners — it’s a choice of Ferrari or Lamborghini. The Roy Hunter and Terry Leonard stocks among these top rifles take a different route to winner’s circle. Both are wood (cedar or other), but super high-tech as they are laminated with carbon fiber. They are beautiful to boot. High-magnification Leupold, March, and Nightforce scopes rule the roost among benchrest optics.
Bullets and Powder
Bullets are important. Really important. A hot bullet gives you “Teen Aggs” and lots of trophies. An average bullet does not. Most of these are 68 grain 6mm boattails. The Peinhardt (StaMoly Precision) bullet is well represented on this list, but some top shooters make their own as you can see. Bullet jackets are likely StaMoly or J4. For powder, nearly everyone shoots Vihtavouri N133 except a few guys running LT30/32 or surplus 8208.

.243 Ackley Improved for Long-Range Varminting and Benchrest Competition
Whenever Matt Bianchini brings his bright yellow .243 Ackley to the firing line, heads turn. This is one truly handsome rig–as good-looking as it is accurate. Built to smoke varmints at long-range as well as compete in 1000-yard benchrest matches, this rifle is proof that competition improves the breed. Fitted with a Farley action, Jewell trigger, Leupold LRT scope, and Lilja or Krieger barrel, the Yellow Ackley is a “no compromise” match rifle that can run with the big dogs in 1K Benchrest competition. And with the Ackley’s ability to toss 106gr Clinch Rivers at 3350 fps, this is one flat-shooting, hard-hitting varmint rifle.
Ultra-Fast, Ultra-Smooth Farley Action…and One Wicked Paint Job
The heart of Matt’s rifle is a Farley action. Farleys have found favor with Benchrest competitors, because the bolt can be worked so fast. And the Farley is as smooth as it is speedy. The difference is quite noticeable if you compare it to a blue-printed Rem 700, or even a recent Stolle Panda. Farleys were true customs, built one at a time by the Farley family in Oklahoma. Unlike a BAT action which is machined from billet steel, a Farley starts with a stainless investment casting, much like Ruger pistol frames. It uses a cone bolt for smooth, yet solid lock-up.
One of the unique features of the Farley is the ejector–it can be switched on or off, depending on the shooter’s preference. So, if you’re load testing some hot rounds, you can turn the ejector off. In a match you can turn the ejector “on” to function normally. Matt is now a confirmed Farley fanatic. He tells us: “I’ve got quite a few other very nice actions, including Nesikas. But none of them are as slick as that Farley. When you work the bolt it feels like it’s on ball-bearings.”
Matt’s Screamin’ Yellow Ackley–The Need for Speed
.243 Ackley Improved Speed Demon
In a long-range varmint rifle, speed kills. Ultra-high velocities will deliver flatter trajectories and more explosive hits on critters. That’s where the .243 Ackley Improved really shines.
Matt has explored the upper limits of .243 Ackley Improved (AI) performance with his yellow long-range rig, fitted with a 29″ Lilja 3-groove, 1:8″-twist barrel. Using a stout load of Alliant Reloder 25, Matt’s “Screamin’ Yellow Ackley” has topped 3340 fps with Clinch River 106s. That’s serious speed for heavy 6mm bullets. This shows a well-built .243 AI leaves Dashers and 6XCs in the dust when it comes to pure velocity.
Ultimate Evolution of the .243 Winchester
Matt’s show-stopping rifle is a .243 Ackley Improved (40-degree shoulder, .271″ neck), chambered with a Manson reamer. On top of the stainless Farley “S” action, in Farley 30mm rings, sits a Leupold LRT (1/16 MOA dot) boosted to 18X-40X by Premier Reticles. Matt has SIX barrels for the gun, three Lilja 3-grooves, a couple Kriegers, and a Shilen.
Matt’s gun currently sports an 8-twist 29″ Lilja 3-groove HV taper that Matt says cleans up like a dream. The stock is a Shehane ST-1000 Tracker made in fiberglass by McMillan, with a BAT trigger guard and Shehane polished billet aluminum buttplate. Prior to final finishing, Matt worked over the flats and some of the angles. That’s why the facets are so well-defined on this rifle compared to some ‘glass Trackers you may have seen. The gun was chambered by Dave Bruno of Cheswick, PA.
Matt bedded the stock and applied the stunning Sikken “Viper” yellow paint job himself. That flawless, smooth-as-glass Screamin’ Yellow finish is no ordinary paint-job, but then Matt Bianchini is no ordinary do-it-yourself painter. His family runs an automotive body-shop, so he had access to premium paints and a quarter-million-dollar spray booth with all the latest technology. Still, Matt spent many hours on this stock to get everything right, trying a couple colors before he settled on a Sikken automotive “Viper Race Yellow” formulated for the Dodge Viper sports car. After careful prep work, Matt sprayed two coats of Viper Yellow, and then added three coats of high-grade automotive clear, which was then baked-on in a heat chamber. Matt also painted the Sinclair front rest to match the stock, and even polished the surfaces of the Hoehn windage top. A lot of effort, Matt told us, was required to achieve the results you see here.
3300 fps for 1000 Yards
Though Matt’s Ackley has harvested its share of varmints, the gun was built with 1000-yard benchrest competition in mind. At left is the firing line at Thunder Valley, Ohio. Yep those targets (upper right) are 1000 yards away. Now you know why Matt has a 40-power scope.
The Yellow Ackley weighs just under 17 pounds to meet IBS and NBRSA “Light Gun” weight limits. While Matt says his bullets don’t “go to sleep” for a couple hundred yards, this gun can still shoot 1/4″ groups at 100 yards and hold that accuracy much, much farther. Matt reports, “my best-ever group was five shots in .397″ at 400 yards. Yep, I got lucky with the conditions, but this is a very accurate rifle.”
.243 Ackley Improved–More Velocity, Less Case Stretch
by Bob Blaine, Sinclair International
Parker Ackley reluctantly developed the .243 Ackley Improved (“AI”). Ackley finally gave in to his customers’ requests to develop the .243 AI. He had always felt that the .243 Winchester was already an improved configuration, but he did say that the best thing to be gained by improving the .243 Winchester was to substantially reduce the case-stretching problems. The .243 Winchester parent case has always stretched brass, almost as bad as the Swift. Even though you get more velocity with the improved .243, I’ve also found that the improved version gives a bit more throat life than the parent case does.
The .243 AI delivers more velocity by virtue of enhanced case capacity–roughly five grains more H20 capacity than a standard .243 Winchester. The .243 AI has a water capacity of approximately 57 to 58 grains, compared to 52-53 grains for the standard .243 Winchester.
Loading for Long-Range
For long-range shooting, Matt loads 106gr Clinch Rivers with 47.5gr of Alliant Reloder 25 for his Krieger barrels, a little more powder with the Lilja 3-grooves. The Lilja load runs 3342 fps, with a 3.228″ OAL. Cases are neck-turned Lapua .243 Winchester. He uses Wilson inline seater and Wilson eck-sizer dies (.267″ bushing), and a custom, reamer-cut FL sizing die.
Not Just for BR, This Gun Can Hunt
While Matt has a big stable of varmint rifles, the Yellow Ackley has seen plenty of duty in the ‘Hog fields. Matt is from a farming family and he can shoot practically right out his back door (see top photo at the farm). He has nailed some big ground-hogs at 800 yards and beyond. The .243 AI does kick a bit compared to other varmint cartridges, but even with 105-106gr bullets, it’s not bad. He has considered adding a muzzle brake at some point to one of the barrels, just so he can see impacts better.
Screamin’ Yellow Dasher?
Matt originally thought of building the gun up as a 6BR or a 6BR Improved. He has a Manson reamer similar to a 6mm Dasher, with a 40-degree shoulder and .008″ body taper. He actually chambered a couple barrels with that 6BR Improved reamer, but he hasn’t shot them yet. He was so pleased with how the gun performed in .243 AI, that he saw no reason to change. And it may be a while before he slaps a Dasher-chambered barrel on the rig: “I really like the way it shoots as a .243 AI. I’m so impressed with it that I don’t want to mess with anything. And I don’t think I’ll be running out of Ackley barrels anytime soon.”
Since the .243 Win is such a popular cartridge, all the major die-makers offer reloading dies. It’s hard to go wrong with a Redding Type ‘S’ Full-length bushing die–item 77114 for the standard .243 Win and item 77420 for .243 AI. Whidden Gunworks also makes great .243 Win sizing dies (and custom .243 Win AI dies on request). These will both resize the case (and bump the shoulder) as necessary, and allow you to adjust neck tension with bushings. Alternatively, you can go with a body die, and a separate neck bushing die.
If you load primarily one brand of bullets, another slick set-up is to buy a Forster or Whidden full-length, non-bushing .243 Win sizing die, and then have Forster or Whidden hone the neck for your desired amount of tension. This elegant one-pass sizing solution produces very straight rounds with low run-out.
For bullet seating, both the Redding Competition Seater (item 55114) and the Forster Ultra-Seater (item U00034) work great for the standard .243 Win case. If you shoot a .243 Ackley, Redding’s .243 AI Comp Seater (item 55420) costs quite a bit more than the standard version Forster doesn’t list a .243 AI seater in their catalog. However, you can just run your chambering reamer into the inner sleeve of either seating die to fit the .243 Ackley Improved case.
If you want the “Cadillac” of production seater dies for the .243 Win, order the Wilson Stainless Micrometer seater (item 50-1114S) from Sinclair International. Costing only a few dollars more than a Redding Comp seater, this die is a joy to use, providing very positive control over bullet seating depth. When used with a quality arbor press, the Wilson offers unrivaled “feel” for bullet-seating force. This can help you monitor neck tension, one of the most critical factors in maintaining low ES and SD for long-range accuracy.

I use a carbide ball on the expander rod of the full length sizing die. I use a .266″ TiN-coated bushing and the ball just kisses the inside walls of the sized neck. I get very consistent neck tension this way and have had no issue with split necks.
Check out those five targets. The Aggregate (average) of all five targets is a tiny 0.0840 inches! These were shot by Gary Ocock at 100 yards in a California benchrest match on August 6, 2017. Though Gary’s 0.0840 Agg beats existing records, this was not a “sanctioned” match, so Gary’s killer Agg was NOT submitted for IBS or NBRSA records. So, sadly, the Agg won’t appear in the record books, but this remains a spectacular, verified feat of rifle accuracy, accomplished in competition.
Retired gunsmith Stan Ware is a talented shooter who’s not afraid to think “outside the box”. Stan competes in both Hunter Benchrest (HBR) and Varmint for Score (VFS) disciplines. In his quest to build the ultimate Hunter Benchrest cartridge, Stan created the radical “Wolfpup” wildcat, based on a 6mmBR parent case. Noting the dominance of 30 BRs in VFS matches, Stan wondered if a stretched 30 BR could work in HBR competition. The challenge was case capacity. Under HBR rules the cartridge must hold at least 45.0 grains of water, equal to the capacity of the classic 30/30 case.

If you load primarily one brand of bullets, another slick set-up is to buy a Forster or Whidden full-length, non-bushing .243 Win sizing die, and then have Forster or Whidden hone the neck for your desired amount of tension. This elegant one-pass sizing solution produces very straight rounds with low run-out.
