At the request of Forum members, we are reproducing this helpful article by gunsmith and Hall-of-Fame benchrest shooter Thomas “Speedy” Gonzalez
How to Reduce Vertical in Your Shot Groups
One of our Shooter’s Forum members recently built a new benchrest rifle. He was concerned because his groups were stringing vertically. This is a common problem that all precision shooters will face sooner or later. In addition to ammo inconsistencies, many other factors can cause vertical stringing. Accordingly, it’s important that you analyze your gun handling and bench set-up systematically.
Hall of Fame benchrest Shooter Speedy Gonzalez has written a helpful article that explains how to eliminate mechanical and gun-handling problems that cause vertical spread in your groups. Speedy’s article addresses both the human and the hardware factors that cause vertical. CLICK HERE to read the full article. Here are a few of Speedy’s tips:
 • Front Bag Tension — Vertical can happen if the front sand bag grips the fore-arm too tightly. If…the fore-arm feels like it is stuck in the bag, then the front bag’s grip is too tight. Your rifle should move in evenly and smoothly in the sand bags, not jerk or chatter when you pull the gun back by hand.
• Sandbag Fill — A front sandbag that is too hard can induce vertical. Personally, I’ve have never had a rifle that will shoot consistently with a rock-hard front sandbag. It always causes vertical or other unexplained shots.
• Stock Recoil — Free-recoil-style shooters should be sure their rifle hits their shoulder squarely on recoil, not on the edge of their shoulder or the side of their arm. If you shoulder your gun, you need to be consistent. You can get vertical if your bench technique is not the same every shot. One common problem is putting your shoulder against the stock for one shot and not the next.
• Front Rest Wobble — You will get vertical if the top section of the front rest is loose. Unfortunately, a lot of rests have movement even when you tighten them as much as you can. This can cause unexplained shots.
• Stock Flex — Some stocks are very flexible. This can cause vertical. There are ways to stiffen stocks, but sometimes replacement is the best answer.
• Rifle Angle — If the gun is not level, but rather angles down at muzzle end, the rifle will recoil up at butt-end, causing vertical. You may need to try different rear bags to get the set-up right.
• Unbalanced Rifle — If the rifle is not balanced, it does not recoil straight, and it will jump in the bags. If the rifle is built properly this will not happen. Clay Spencer calls this “recoil balancing”, and he uses dual scales (front and rear) to ensure the rifle recoils properly.
• Firing Pin — A number of firing-pin issues can cause vertical. First, a firing pin spring that is either too weak or too strong will induce vertical problems. If you think this is the problem change springs and see what happens. Second, a firing pin that is not seated correctly in the bolt (in the cocked position) will cause poor ignition. Take the bolt out of rifle and look in the firing pin hole. If you cannot see the entire end of firing pin it has come out of the hole. Lastly, a firing pin dragging in bolt or shroud can cause vertical. Listen to the sound when you dry fire. If you don’t hear the same sound each shot, something is wrong.
• Be Consistent — You can get vertical if your bench technique is not the same every shot. One common problem is putting your shoulder against the stock for one shot and not the next.
• Head Position — Learn to keep your head down and follow-through after each shot. Stay relaxed and hold your position after breaking the shot.
• Last Shot Laziness — If the 5th shot is a regular problem, you may be guilty of what I call “wishing the last shot in”. This is a very common mistake. We just aim, pull the trigger, and do not worry about the wind flags. Note that in the photo below, the 5th shot was the highest in the group–probably because of fatigue or lack of concentration.

“The blue plastic barrels that we have to shoot through are the idea of the local police — to ensure that we keep our rifles pointing at the targets!” — David Sharp
Here’s a great story from the other side of the pond — the United Kingdom. Shooting a .308 Win factory Savage rifle, a novice benchrest shooter set two new 1000-Yard UK Factory Sporter Class records with a group barely over three inches plus a 6.756″ four-group Aggregate. The Savage had been upgraded with an inexpensive aftermarket stock and Timney trigger, but was otherwise “as manufactured” — with factory barrel.
At Ingleston, competitors shoot for group size only — so there are no scoring-rings on the targets.
On October 14, 2018 David Sharp had a memorable performance at the Ingleston Range in Scotland. David Agg’d 6.756 inches for all four 5-shot groups, a new UK 1000-Yard record for the Factory Sporter Class. His smallest group measured 3.090 inches, which is also a new UK Factory Sporter record. Great Shooting David — congrats!
Sharp Sets Two New UK Factory Sporter Class 1000-Yard Records
Report by Vince Bottomley
In the UK, long-range benchrest is far more popular than short-range. The UKBRA (United Kingdom Benchrest Association) holds shoots at three venues: Diggle (100, 600 & 1000 yards), Bisley (100 yards only) and Ingleston in Dumfries, Scotland (1000 yards).
The Scottish venue is the UK’s latest 1000-yard facility. It was established just three years ago yet it is already holding well-attended monthly shoots. It is operated by the Galloway Small Arms Club and, as you may imagine, it is situated in the beautiful wild Scottish countryside.
The UKBRA operates under IBS/NBRSA rules for the Light and Heavy Gun Classes but, many of the Scottish members are also deer stalkers and came to the benches with their hunting rifles, so we also run a Factory Sporter Class. Factory Sporter rifles must be the original manufacturer’s barreled-action but a more benchrest-compatible stock may be used or ‘bag-rider’ attachments may be fitted to the butt and fore-end. The barreled-action must however be totally as it left the factory — no re-chambering or throating, though the crown may be re-cut. To discourage potentially dangerous trigger modifications, an after-market trigger may be fitted.
The Factory Sporter Class is very popular and Savage rifles, chambered for the 6mmBR, 6.5-284, and .308 Win are the favored factory-classers. These have produced some remarkable performances over the years, often out-performing custom rifles!
David Sharp is a True Sharp-Shooter
David Sharp is a relatively new benchrest shooter, though he has decades of firearms experience. David started his shooting days wild-fowling and rough shooting with a shotgun over 50 years ago. After retiring, he moved to Dumfriesshire and began shooting again — clay pigeon, wildfowling on the Solway, driven pheasant and deer stalking. As a stalker, David keeps his eye in by shooting targets on a local range using his .308 Mannlicher.
Eventually, the pains of old age began taking their toll and stomping up hills was becoming more difficult. Fortunately, David heard about the Ingleston 1000-yard range and joined the Galloway Small Arms Club in 2016. As a complete novice to benchrest shooting, David relied on the guidance and advice from his fellow Club members and eventually purchased a Savage Model 12 F-TR rifle in .308 Winchester to compete in the Factory Class.
Here’s the view looking downrange. What a beautiful place to shoot…
.308 Win Factory Savage with Choate Stock and Vortex Scope
David’s rifle has some upgrades, as permitted for Factory Sporter Class. The Savage trigger was replaced with a Timney. The Savage F-TR stock was replaced with a Choate Varmint stock fitted with a Sinclair front bag-rider. The Choate’s butt was home-modified to better ride the Edgewood bag. The rifle is fitted with a Vortex Golden Eagle 15-60 scope mounted on a 20 MOA Ken Farrell rail via Vortex rings. Dave shoots off a SEB Mini front rest. As the Mini is lighter to lug around than the SEB NEO (and less expensive), the Mini is becoming popular with UK shooters.
David reports: “My rounds are nothing special — I’m using Sierra 2155 155 grain bullets over Vihtavuori N140 powder and CCI 200 primers. I use Lapua brass (large primer) full-length sized in a Redding S bushing die to give 0.002″ neck-tension.”
Although the Ingleston Range is a beautiful place to shoot, as you can imagine conditions can vary dramatically and it is not known for mild days! However, at 9:00 am on the day of David’s record shoot, it was clear and quite still with the flags barely lifting. The temperature was already 15 deg C (59 deg F). What more could any benchrest shooter ask for?
In the photo of David above, you can just see the four 1000-yard targets in the extreme top right of the picture — up near the tree-line. Note, at Ingleston, competitors shoot for group size only. Hence there are no scoring-rings on the target. However, Vince Bottomley says score shooting may begin at some UK ranges: “This year we have purchased a set of electronic targets. The IBS target face can be inputted so we will now start to shoot for score as scores are registered instantly. Previously, it just took too long to score the targets as well as measure the groups.”

Get a video view of 1000-yard Benchrest competition tomorrow on Shooting USA television. This week’s Wednesday episode of Shooting USA features the 2017 IBS 1000-Yard National Championship held at the Whitehorse Shooting Center in Peeltree, West Virginia. This Shooting USA episode takes you to the Whitehorse 1K Range in September 2017. You can see the action on the firing line and the Shooting USA team also interviews many competitors. Watch this episode on the Outdoor Channel at these times: 9:00 PM Eastern and Pacific; 8:00 PM Central.
If you want to learn about the 1000-yard Benchrest game, definitely tune in to Shooting USA on September 26, 2018 (tomorrow) to watch last year’s IBS action. There were nearly 120 shooters competing (118 in Light Gun, 107 in Heavy Gun).
To learn more about on this event, read our detailed 2017 IBS 1K Nationals Match Report. At the 2017 Nationals, conditions were challenging to say the least, with rain storms, spiraling winds, and fog. In fact, rain and fog on Saturday (with cancelled relays) caused the Nationals to be extended by one day through Monday. What’s more, of the 107 shooters listed in the Two-Gun Overall results who actually shot both guns, there were dozens of DQs. (Yes, the wind was very tricky at this year’s Nationals.)
Top Guns at the 2017 IBS 1000-Yard Nationals were Edward Kenzakoski (Two-Gun Overall Champion), Mike Gaizauskas (Light Gun Overall, plus LG Score Agg), and Mike Brennan (Heavy Gun Overall, plus HG Score Agg). Group Agg winners were Richard Schatz for LG, and Charlie Lentz for Heavy. Two ladies also deserve mention. Sally Bauer shot the smallest group of the match, a 1.923″ 5-shot group in LG — that’s 0.184 MOA! Ruth Edwards drilled a 2.104″, also mighty impressive. Here’s Sally below with her very patriotic Heavy Gun…

 Have a good look at the photos below — this may be one of the most noteworthy target strings we’ve ever published. What you can see is the effect of barrel tuner position on point of impact (POI). You can clearly see that the tuner position alters the up/down POI location in a predictable fashion.
This remarkable 15-shot sequence was shot by French benchrester Pascal Fischbach using his 6 PPC fitted with a CG (Carlito Gonzales) action and a Bukys barrel tuner.
Pascal reports: “After [bullet] seating and load validation, I put the Bukys tuner on, screwing it out 10 turns. According to Carlito, the CG’s super stiff action-to-barrel fit gives a faster vibration modulus that is detrimental below 10 turns [position of the tuner].” Pascal’s procedure was to screw out the tuner 1/4 turn progressively from one shot to the next. He shot one bullet at each tuner position, with a total of 15 shots.
15-Shot Sequence with Tuner Changes
CLICK HERE to SEE Large Version of Complete Test Strip (All 15 shots in a row).
Left Half of Target Strip (shots with 1/4 rotation change of tuner in sequence)
Right Half of Target Strip (shots with 1/4 rotation change of tuner in sequence)
Pascal observed: “Note the point of impact displacement [from shot to shot] tracks clearly along a sinusoide (sine wave curve).” This is indeed notable and significant! This shows how the tuner’s ability to change barrel harmonics can alter the position of the muzzle as each bullet exits, resulting in a higher or lower POI. Pascal sent his results to Carlito Gonzales in Argentina for analysis.
Pascal poses this question to readers: “Guess which three positions Carlito recommends to try?”
Editor’s Note: While this target sequence clearly shows how tuner position can alter bullet point of impact, this, by itself, does not tell us which tuner position(s) are best for accuracy. That will require further multi-shot group testing, involving careful experimentation with tuner position (and powder charge weights). But for those folks who doubt that a tuner can make a difference on a short, fat barrel, just take another look at the photos. The up/down changes are undeniable, and noteworthy in the wave pattern they follow.
Shooting Set-up and Test Conditions:
Pascal did this test at an outdoor range under very good conditions: “This was shot at my home range, outdoors, with four Smiley flag. The range is a narrow cut in high woods. Wind was consistent with readable flags. I started testing the tuner from 10 turns out and on to 15. I recently… found a sweet spot very close to the rearmost position of the tuner, so the rigidity provided by this super long tenon (just short of 70mm) was not a reason to overlook the recommended Bukys tuning procedure.”

From the late ’70s through 1983, a huge, concrete-walled warehouse in Houston was used for benchrest testing. Virgil King and Bob Fisher set up a bullet-catching backstop at the end of a 30-yard-wide, 325-yard-long fire lane that remained unobstructed even when the warehouse was in use. This allowed accuracy tests in virtually perfect “no wind” conditions. Over a six-year period, about 30 shooters were invited to test their rifles. The results were amazing, with numerous “zero groups” being shot in the facility. Many of the lessons learned in the legendary Houston Warehouse still help benchresters achieve better accuracy today.
Dave Scott wrote a superb article, the Secrets of the Houston Warehouse which appeared in a special issue of Precision Shooting Magazine. That issue has long been sold out, but, thankfully, Secrets of the Houston Warehouse is now on the web: CLICK HERE to READ Secrets of the Houston Warehouse.
 Dave Scott explains why the Warehouse was so unique:
“Over a period of six years, the levels of accuracy achieved in the Houston Warehouse went beyond what many precision shooters thought possible for lightweight rifles shot from sandbags and aimed shot-to-shot by human eye. For the first time, a handful of gifted, serious experimenters — armed with the very best performing rifles (with notable exceptions) — could boldly venture into the final frontiers of rifle accuracy, a journey made possible by eliminating the baffling uncertainties of conditions arising from wind and mirage. Under these steel skies, a shooter could, without question, confirm the absolute limits of accuracy of his rifle, or isolate the source of a problem. In the flawlessly stable containment of the Houston Warehouse … a very few exceptional rifles would display the real stuff, drilling repeated groups measuring well below the unbelievably tiny .100″ barrier. The bulk of rifles, however, embarrassed their owners.”
Scott’s article also reveals some interesting technical points: “One thing that IS important is that the bullet be precisely seated against the lands. T.J. Jackson reported this fact in the May 1987 issue of Precision Shooting. In a letter to the Editor, T.J. wrote, ‘…in all our testing in that Houston warehouse… and the dozens and dozens of groups that Virgil King shot in there ‘in the zeroes’… he NEVER fired a single official screamer group when he was ‘jumping’ bullets. All his best groups were always seated into the lands, or at the very least… touching the lands. Virgil said his practice was to seat the bullets so the engraving was half as long as the width of the lands. He noticed an interesting phenomenon with rifles that could really shoot: if the bullets were seated a little short and the powder charge was a bit on the light side, the groups formed vertically. As he seated the bullets farther out and increased the powder charge, the groups finally became horizontal. If he went still farther, the groups formed big globs. He said the trick is to find the midway point between vertical and horizontal. That point should be a small hole.”
You should definitely read the complete article, as it provides many more fascinating insights, including shooting technique, barrel cleaning, neck-turning, and case prep.

With the recent IBS 100/200 Group Nationals in Pennsylvania, we thought our readers might like to learn more about the short-range Benchrest game. Seeing the tiny groups 6 PPC aces produce, it’s easy to think the precision is all about the equipment. But there is a lot more involved. A talented human still has to watch the flags, run the gun properly, and tune his loads for the conditions. Here are some tips from one of the world’s best benchresters, Charles Huckeba.
Texan Charles Huckeba was the top individual shooter at the 2013 World Benchrest Championships (WBC) held near Sydney Australia in October 2013. In this video, 2013 WBC Two-Gun Overall winner Charles shoots a 1/8th MOA group at 200 yards — “a little bitty dot” as a fellow Team USA shooter observes. That’s impressive. If you can describe Huckeba’s style in a nutshell it would be “smooth, consistent, and rapid but not hurried”.
Charles also employed some unusual hardware. In the video, take a close look at the joystick on the Farley Coaxial front rest. There’s no knob at the end. In its place is a small, wood ammo caddy. Charles removed the standard knob from the handle of his Farley rest and replaced it with a home-made wood block that holds cartridges for the record target. The 10.5-lb Light Varmint rifle is chambered in 6PPC with a BAT Machine Action and a composite wood and carbon-fiber stock.

Here is the actual 200-yard, 5-shot group Charles shot in the video. Photo (by Stuart Elliot) taken through the lens of Huckeba’s 50X March scope (reticle has 1/16th MOA Dot).
Analyzing the Fine Points — What Makes Huckeba So Good
Short-range benchrest shooter Boyd Allen saw some interesting things in Huckeba’s WBC performance, as captured on video. Boyd noticed Huckeba’s smooth gun-handling and efficient loading. But Boyd also spied some interesting equipment, including an innovative joystick “handle-caddy”.
1. Low Friction Bags — When Huckeba slid his rifle, there was very little apparent friction. The front bag features the new 3M material (ScotchLite) on the sliding surfaces. The rear Protektor bag has ears of the same low-friction material.
2. Pause Before Chambering — While he was watching the flags and deciding when to start firing, Charles kept his first round in the action, but out of the barrel’s chamber, probably so as not to heat the cartridge and change the round’s point of impact.
 3. Ammo Caddy on Joystick Arm – Charles shoots a Right Bolt/Left Port action, so he pulls his rounds with his left hand. Note that Huckeba’s record rounds rest in a small, wood ammo caddy attached to the end of the joystick shaft. Look carefully, you’ll see the wood ammo block in place of the normal black ball at the end of the joystick. That allows Charles to pull shots with the absolute minimum of hand movement. Ingenious! Huckeba is very fast, with a great economy of motion. I believe that because his ammo was literally at hand, Charles was better able to keep his focus on aiming and the flags.
4. Smooth-Cycling BAT Action — Note how smoothly Huckeba’s action operates. When Charles lifts the bolt handle (to extract a round and cock the firing pin), this does not disturb the rifle. Likewise, as he closes the bolt, the gun doesn’t wobble. The smooth action allows Charles to hold point of aim even when shooting relatively quickly. Huckeba’s BAT action is chrome-moly steel. Some shooters believe this metal makes for a smoother action than stainless steel or aluminum.
5. Long-Wheelbase Stock — The wood and carbon fiber stock is light, long, and stiff. Yet, importantly, the stock is also well-damped. The longer-than-average stock length (with extended forearm) seems to help the gun track well without jumping or rocking. The longer forearm allows a longer “wheelbase”, effectively shifting the weight distribution rearward (less weight on the front, more weight on the rear). This places a greater share of the gun’s weight on the rear bag, as compared to a more conventional benchrest stock. Huckeba’s stock, built by Bob Scoville, is at the cutting edge of short-range benchrest design. Its light-weight balsa wood and carbon fiber construction provides a combination of stiffness and vibration damping that allows its relatively long fore-end to be fully utilized to increase the weight on the rear bag (always an issue with 10.5-pound rifles).
To learn more about this benchrest stock design, read the comments by stock-builder Bob Scoville in our PPC with Pedigree story in our Gun of the Week Archives. Bob observed:
“There is a lot more to the structure of the stocks than meets the eye. The carbon fiber skin with which I cover the stocks creates a light, tough exterior surface. However, this contributes very little to the overall performance of the stocks. The real strength and stiffness is the result of an internal beam utilizing balsa core/carbon fiber technology.
This type construction can be found in aircraft, race cars, powerboats, and sailboats. It is interesting to note, balsa has the highest strength to weight ratio of all woods and carbon fiber is one of the lowest stretch (modulus of elasticity) relative to weight of all materials. The marriage of these two materials is common in the high-performance world. Additionally, balsa is used commercially for vibration dampening and sound reduction.”

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.
Junebug’s Rifle Specifications
Stock: Zebra-painted stock (Shehane ST1000 we believe)
Action: Stiller Diamondback
Scope: March 10-60x52mm with 1/8 MOA clicks
Cartridge: 6mm BRDX (6mmBR Norma 40° Improved similar to Dasher)
Bullet: 103-grain Vapor Trail
Gunsmith: Barrel smithed by Tim Claunch, Memphis, Tennessee

Held July 14-15 at the Original Pennsylvania 1000-Yard Benchrest Club, the 2018 Williamsport World Open attracted a large field, with over 130 competitors. During the two-day event, shooters competed in a four-match Aggregate comprised of one Light Gun Match and one Heavy Gun Match on Saturday followed by LG and HG matches on Sunday. The conditions this year were switchy at best, with light rain Sunday morning preceding the start, and typical Williamsport winds. CLICK HERE for complete results.
Check out this superb 100-8X group. Could your rifle do that at 1000 yards?
Pit Duty at Williamsport.
Kieffer Dominates Match, Winning Both Classes and Overall
David Kieffer dominated the 2018 World Open. This talented shooter earned multiple titles: Two-Gun Grand Champion, Light Gun Grand Champion, and Heavy Gun Grand Champion. David had a steller performance with a 5.433 Two-Gun Group Size Aggregate. Shooting a 6.5×47 Lapua rig smithed by Mark King, Kieffer won the Two-Gun Overall with 10 Rank points (lower is better). Second in Two-Gun was Charlie Lentz with 47 Rank Points. Third was Charles Loebsack with 52 points. There was a turn-out this year of 130 entries in Light Gun Class (17-lb limit, 10 shots per target) class and 130 shooters in Heavy Gun Class (Unlimited weight, 10 shots per target).
Winning Equipment: Dave Kieffer’s winning rifle was a Mark King built 6.5×47 Lapua using H4350 and 140 grain Berger bullets. This featured a BAT action, Krieger barrel, and Nightforce action.
At Willliamsport, the range drops away beyond the firing line, and then rises up again for the target line and pits. There is even a pond down range. This makes for a very scenic view, but also challenging conditions. The Williamsport range is known for tricky winds, with switches and let-ups. There are several flags between the firing line and the 1000-yard targets. It is common to see them pointing in different directions, adding to the challenge.
New Benches at Williamsport 1000-Yard Range
The firing line for the 1000-yard range went through a complete renovation before the 2018 season. Added were 15 new masonry benches with block bases and concrete/plywood tops. The structure over the benches is completely new as is the concrete pad underneath the benches.

Forum member Evan K. (aka “Katokoch”) has crafted a nice rimfire benchrest rig using a Suhl action fitted into a handsome home-built cedar and carbon fiber stock. This shows what a skilled hobbyist wood-worker can create in his garage. Evan tells us: “Here is my Suhl 150-1 with a factory 1:19″ twist barrel, Leupold 36X scope, Harrell tuner, and my handmade cedar/carbon fiber stock. I started working on the laminate blank a couple years ago and finally finished it earlier this year. I’ve been using it in my IR 50/50 matches this summer. I haven’t shot a 250 with it yet but I know the rifle is very capable — as usual, I am the weak link!”
We think Evan did a great job on his stock, though he has limited stock-building experience. Evan explained: “The stock is my first attempt at making a very lightweight laminate and also gluing both vertical and horizontal seams in a blank. The wood is Spanish and Red Cedar and I made the trigger guard and buttplate with carbon fiber too (great use for small scrap pieces). The finish is hand-rubbed spar urethane and the action is semi-glued-in with Devcon 10110 and stainless pillars.”
USRA-IR50/50 is a popular .22 rimfire benchrest discipline with three (3) classes: 13.5 lb., 10.5 lb., and 7.5 lb. (Sporter). The matches are shot at 50 yards and 50 meters.

World Record group shot by Bart Sauter in IBS 600-yard Match on April 21, 2018 in Memphis, TN.
0.282 inches, 0.04 MOA… at 600 Yards. Simply amazing…
What can we say… this 0.282″ 5-shot group 600 yards represents one of the most impressive feats of rifle accuracy in history. Shot in competition, this five-shot group at 600 yards easily fits inside a dime with plenty of room to spare!
Bullet-maker Bart Sauter recently shot this 0.282″ five-shot group at a 600-yard IBS match. Yep, you read that right — 0.282″ at 600. Most shooters would be happy with that group at 100 yards. At 200 it would be remarkable. But at 600 — it is truly amazing. Readers, 0.282″ at 600 works out to 0.04 Minutes of Angle (MOA). Not point four MOA, but point ZERO four MOA, and it was all in the TEN RING for a 50 score. Even measured outside edge to outside edge, that group is just 0.525″, so Bart’s group will easily fit inside a dime (0.705″ diameter).
Sauter’s amazing 0.282″ 50 group smashes the existing IBS Heavy Gun 600-yard record, a 0.404″ shot by John Lewis way back in 2008. It also happens to beat the existing IBS Light Gun group record — the stunning 0.336″ by Rodney Wagner in 2013. (A group many said could never be bettered). Bart’s group will be a new score record too — many 50s have been shot before, but the group size is the tie-breaker, and no one has ever shot smaller at 600 than Bart.
Sauter Smashes IBS World Records with Stunning 600-Yard Group
Report by Boyd Allen, IBS Vice President
On the 21st of April, at the beautiful Memphis Sport Shooting Assn. 600-yard benchrest range, bullet-maker Bart Sauter made history. About 11:00 O’clock with 12-15 MPH switchy winds, Bart Sauter waited for his chosen condition and then ran five shots into an incredible 0.282″ record-breaking group, with a score of 50. Shot in Heavy Gun Class (with his Light Gun), this combination of group and score bettered the previous HG group and score records with sufficient margins that their records in both categories are virtually guaranteed. The previous group record, a 0.404″, belonged to John Lewis and stood for ten years. The previous score record was 50/.513 (group size being the tie breaker) shot by B.J. Francis last year. Bart’s target was 50/.282.
To put it in perspective Bart’s record has the equivalent angular dispersion (MOA) of a .04″ group shot at 100 yards. (Bart’s exact MOA is 0.0448) But consider that crosswinds have roughly 36 times more effect at 600 yards than at 100 yards (by the “Rule of the Square”).
Record-Setting Cartridge and Load with Bart’s Own 105gr Bullets
Bart shot a 6mmBR Ackley Improved (6BRA) wildcat cartridge with an 0.272″ neck. This is basically the 6mmBR Norma with a 40° shoulder. The neck is long like the parent cartridge, not short like a 6mm Dasher. Bart was shooting his own 105 grain, 13 Ogive VLD bullets. He calls this new bullet design “The Hammer” (for good reason). Bart’s Hammer 105s were loaded in Lapua brass with Hodgdon H4895 powder and Wolf primers. Bullet tips were trimmed on a Giraud bullet point trimmer, but not pointed. Bart feels that there is too much potential for damaging bullets during pointing, so he does not point his match bullets. Bart had his LabRadar chrono on the bench during the match. Velocities were 2970-2975 fps with single-digit ES.
Record-Setting Rifle — IBS Light Gun Shot in Heavy Gun Class
Bart’s rifle features a melonited BAT B action, with a 26″, 1:8″-twist, HV contour James Lederer barrel, fitted with a Mike Ezell tuner. The Jewell trigger was set to 1.5 ounces. On top was a March 40X in BAT rings. The initial build was by Mike Moses, with chambering by Dean Stroud, and final (glue and screw) bedding by Billy Stevens. The handsome wood JB 1000 stock (3″-wide fore-end) boasts an aluminum keel added by Alex Wheeler after the initial build. Bart said that it only took him 15 minutes to adjust the keel so that the cross hairs did not wiggle on the target when the gun was pulled back a full 2 ½ inches. Bart is definitely a fan of the adjustable keel.
Bench Equipment and How Rifle Was Shot
Bart used a Farley Coaxial front rest with soft leather Edgewood front back sprinkled with baby powder. In the back was a Protektor Model DR rear bag with Cordura ears and no added lube (not needed with aluminum keel) borrowed from Mike Moses. Bart shot the rifle lightly pinned between his shoulder and the fore-end stop. Interestingly, Bart kept his Labradar chronograph on his bench throughout the day, and recorded velocities during the record group: 2970-2975 fps with single-digit ES.
 Reloading Equipment and Methods
After firing, cases are annealed with a Benchsource flame annealer. The inside of the case-necks are brushed with a nylon brush (no lubricant is used). Cases are sized with a custom Whidden Full-length sizing die (with bushings), and a cut-down Wilson micrometer seater that was originally made for the Dasher.
Bullets are seated with a 21st Century Shooting Hydro Bullet Seater, used with the Wilson cut-down Wilson seating die. This state-of-the-art arbor press boasts a hydraulic seating pressure cylinder and gauge. During seating, the force gauge reads about 27.
The powder charge is first thrown from a manual measure and usually trickled onto an A&D 120 FXi magnetic force restoration scale using an Adams automatic trickler, but this time Bart had to settle for his old RCBS trickler because the drive band of the Adams auto-trickler wore out.
Brass Prep — The chamber is a 0.272″ no turn. Bart lightly skims the necks AFTER the first firing just enough to achieve batch to batch uniformity in neck thickness. He uses a .266 bushing which gives him .003 neck tension.
Pre-Loading vs. Loading at the Range
I asked Bart if he pre-loads, or loads at the range. Unexpectedly his answer was “Both…depending”. Bart will identify his “in tune” velocity at his home range and then pre-load that load before the match. However, Bart takes all of his reloading equipment to the match, and if the conditions are such that his pre-loaded ammunition does not give the velocity he wants (as revealed by the LabRadar), he will load at the match.
Another test that he feels is important is to be able to pass a bullet all the way through the neck of his fired cases. Bart thinks that even if the shank of a seated bullet does not directly contact a doughnut, that doughnut can have a negative effect on accuracy.
Bart has brought short range benchrest know-how to 600-yard competition. He uses a full set of short range flags, shown above. At last year’s Nationals, at the same Memphis range, Bart was one of the only shooters with a set of flags. Now other 600-yard competitors are following suit. |
Final Throughts — The 6BR Ackley vs. 6mm Dasher
Given its prominence, it is inevitable that comparisons be made between the 6mmBR Ackley Improved and the Dasher. On this subject Bart told me that, based on his experience, he is a “Dasher basher”. He believes the Dasher can be finicky, and has a tendency to flip shots out of the group. For Bart, the 6BR Ackley has been a lot easier to work with and more predictable.
Below is a test target Bart shot at 100 yards. The load yielding the smallest 3-shot group, measuring 0.092″, was the load Bart took to the match. As you can see, the positions of the various load adjustments did not change on the targets. Bart said that that is the kind of positive compensation that he likes to see.
While Bart does most of load testing at short range, he can shoot out to 500 yards near his home. He says his record-setting gun has produced multiple 500-yard, 3-shot groups in the “three-quarter inch range” when testing in calm conditions. That’s 0.14 MOA for three shots. At 500…
Congratulations to Bart on His Great Shooting
Finally, I would like to add my congratulations to Bart Sauter for this spectacular group. I also want to thank Bart for generously taking the time to share the details of his load, reloading methods, and rifle components. Bart has shown that applying some short-range benchrest techniques to the mid-range game can produce remarkable results.
