Gary Ocock Shoots Amazing 0.0840 Aggregate with Railgun

Gary Ocock Rail Gun Unlimited Target Visalia CA 6 PPC IBS NBRSA
Want to see the details? CLICK HERE to view full-screen photo.

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 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.

*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.

Blast from the Past — Setting Benchrest Records in 1955


Barney M. Auston of Tulsa, OK with rifle he built to break NBRSA record and win $250 cash award from Sierra Bullets. (From cover of Precision Shooting magazine. May 1956).

Way back in 1955 Sierra Bullets offered a $1000 prize for anyone setting a new Aggregate benchrest record with a 6mm (or larger) bullet. At the time the .222 Remington ruled the roost, and Sierra wanted to promote the larger caliber. Sierra also offered a $250.00 prize for a record-breaking performance with any size caliber (including the .22s). Here is the story of how a Tulsa shooter claimed the $250.00 award with a world-record-setting Aggregate involving 10-shot groups at 100 and 200 yards.

Barney Auston’s record-setting rifle was built on an FN Mauser action with double set trigger, with a Hart stainless steel barrel, 30″ x 1 1/8″, chambered for the .222 Remington cartridge. The stock, made by Auston, has a hydraulic bedder as made by L. F. Landwehr of Jefferson City, MO. The scope is a 24X, 2″ inch Unertl. Mr. Auston shot 50gr bullets, custom made by W. M. Brown of Augusta, Ohio, with .705″ Sierra cups and soft swedged. His powder charge was 21 grains of 4198. The rifle rests, both front and rear, were also made by Auston.

Record-Setting Performance
On August 20, 1955, shooting at night in a registered shoot on the John Zink range near Tulsa, Oklahoma, Barney M. Auston of Tulsa broke the existing National Match Course aggregate record and, as the first to do that in 1955, won the Sierra Bullets $250 cash award. Here is the original Sierra Bullets prize offer from 1955:

10-Shot Groups at 100 and 200
Mr. Auston’s winning Aggregate for the National Match Course (five 10-shot groups at 100 yards and five 10-shot groups at 200 yards) was .4512 MOA. He also broke the 200-yard aggregate with an average of .4624 MOA, beating the .4801 match MAO record set by L.E. Wilson only a month earlier.

Barney Auston was a custom rifle maker in Tulsa who fabricated the rifles used by many of the leading benchrest competitors in the Mid-Continent and Guild Coast Regions. Auston was himself one of the top benchrest shooters in those regions during his shooting career.

Editor’s Note: Both of Mr. Auston’s records were broken before the end of the 1955 shooting season, but Auston was the first to win the Sierra Prize. Interestingly, in setting his record, Austin broke the existing Agg record by L.E. Wilson of Cashmere, Washington — yes, the same L.E. Wilson that now makes dies.

Old Guys Rule! 60-y/o Betzold Wins Garand and Carbine Matches

Camp Perry CMP Trophy  Games M1 Garand Carbine 3-Gun Aggregate National Matches

Victor Betzold had a Camp Perry experience for the ages. At the 2015 CMP Games, Betzold won the Garand Match, won the M1 Carbine Match (setting a new Record), and took the 3-Gun Aggregate for the second year in a row. Now that’s an impressive performance. Betzhold is no stranger to shooting – beginning in junior high and firing well into college, then taking his love for guns into the Army. After the years went on and work and family became higher priorities, he fell away from the sport he loved. But now that he’s retired at age 60, he’s had time to practice again – practice that has certainly paid off.

During his remarkable showing at the National Games Matches, Betzold won the Carbine Match with a score of 375-6X, setting a new National Record in the process. In the National Garand Match, Betzold fired a score of 290-7X to become the overall winner of a field of 1213 competitors.

“It feels great,” he said. “I’ve been working at this for a long time.” The 60-year-old Betzold was also the top senior for both the Garand Match and the Carbine Match.

With his outstanding performances in the Garand and Springfield Matches, as well as an exceptional seventh-place finish in the Vintage Military Match, Betzold claimed the 3-Gun Aggregate title for the second year in a row — with a combined score of 865-19X.

Murdica’s Masterpiece — Just About as Good as It Gets

Lou Murdica Railgun NBRSA Record one-hole 6PPC Berger Bullets kelbly Action

Sometimes superlatives really aren’t necessary. Just look at that target. Yes that is FIVE shots (although it truly appears like one hole). And it is centered! This remarkable group, measured at 0.039″, was shot by Lou Murdica in Phoenix on January 3, 2015. Lou drilled this group with his 6 PPC railgun. Rounds were loaded with Accurate LT-32 powder and Berger 65gr BT bullets. The target will be submitted to the NBRSA as a potential new 100-yard Benchrest record in the Unlimited (Railgun) Class. The current NBRSA record small group (Unlimited) is a 0.049 shot by Hall-of-Famer Gary Ocock in 2009.

This is a file photo with a different railgun.

This wasn’t the only tiny group shot by Lou over the weekend. Murdica shot a sizzling 0.1262 five-target 100-yard Unlimited Aggregate. That 0.1262 Agg will also be submitted for consideration as a possible record. Here are the individual group sizes: 0.104, 0.183, 0.201, 0.104, 0.039. At this match Lou won both the Unlimited and Sporter class. “It was a great weekend” Lou reported.

About the Gun
What kind of rifle can put five shots in one hole? Lou was shooting an Unlimited-class railgun. This return-to-battery rig (a Kensler railgun) allows the shooter to focus on firing at the perfect time for the conditions. Lou’s Kensler railgun (see below) features a Kelbly top-loader Grizzly action, Shilen 6-groove barrel, and March 10-60X scope. The Shilen is chambered for the 6 PPC cartridge. But there’s something special about this particular 6 PPC — read on….

Click photo for larger version:
Lou Murdica Railgun NBRSA Record one-hole 6PPC Berger Bullets kelbly Action

Radical New Reamer Design from PT&G
Lou used a new chamber reamer from Pacific Tool & Gauge (PT&G) with special geometry in the leade/throat section. Called a “Bore Rider” (or sometimes “bore-runner”), this new reamer design cuts a staged, variable taper in the leade/throat area that is quite different than the taper in a typical throat. It’s a little hard to explain, so we’ve included the 6 PPC Bore Rider reamer print below. (Download the PDF file for a better view.) Experts should look at the leade angle(s), freebore, and throat dimensions. You may be surprised. Dave Kiff of PT&G says this Bore Rider design has worked successfully for other cartridge types/calibers as well. Apparently this design helps the bullet center up smoothly in the bore before the bullet engages “hard” in the rifling — or so we’ve been told.

Profiles in Accuracy: Jenkins Sets 600-Yard Agg Record with 6BR

Last month, shooting at the Piedmont Gun Club, Chad Jenkins put together a stunning 1.495″ Aggregate at 600 yards. Once certified, that will be a new IBS 4-target Light Gun record. Chad’s smallest group was a 1.033″. Chad’s 1.495″ Agg breaks the existing 1.6068″ record set by Sam Hall in 2011. Chad was shooting a no-turn-neck 6mmBR featuring a BAT action, Krieger barrel, and Shehane ST-1000 fiberglass stock. We had the chance to talk with Chad and learn more about his record-setting rifle, and the methods he uses to achieve superior accuracy. Chad was kind enough to tell us about his equipment and what he does to build very, very accurate ammo. For starters, Chad wanted to “say thanks to Lewis Winkler, James Coffey, Mike Davis, and Larry Isenhour” all of whom provided invaluable help and support over the years.

The Record-Setting Rig
Chad credits much of his success to an “fantastic Krieger barrel that shot great right out of the gate”. It’s a 1:8″ twist, HV contour, finished at 28″ — nothing unusual there. Mike Davis did the chambering, barrel-fitting, and barrel crowning. One reason the gun shoots so well is that Chad’s friend James Coffey did the stock work and bedding, and also added weight to the Shehane ST-1000. Chad says “James really knows what he’s doing”. For optics, Chad uses a Leupold 45X competition scope, with fine cross-hair (FCH). Chad says he can “aim at the ‘X’ at 600 yards more precisely with the cross-hairs than with a target dot.”

Chad Jenkins Aggregate IBS Record

$200 Front Rest Good Enough to Set Record
You may be surprised that Chad set his record with an inexpensive Caldwell Fire Control Joystick rest, that sells for about $203.00 on Amazon.com. The Caldwell isn’t fancy, but it did the job. Chad says: “I have a family and a young boy. I don’t have the money to pour into equipment like some other people. I will continue to use my Caldwell, but I have recently modified the base. The record though was set with an unmodified unit, just as it appears in the photo.”

Chad Shoots a “Classic” 6BR Load, But He Jumps his Berger VLDs
Chad gets great accuracy with a pretty “standard” 6mmBR match load: 30.5 grains Varget, CCI 450 primers, Berger 105gr VLDs, in Lapua “Blue Box” brass. (Editor’s Note: That load can be too hot in some guns in summer conditions). Chad loads his ammo with a Redding bushing full-length sizing die with an 0.266″ bushing. Chad says: “That’s a good size for the ‘Blue Box’ Lapua brass (I tried a 0.268″ and I could pull the bullets out with my fingers). I seat my bullets about 0.020″ OFF the lands with a Redding Comp seater die.” The brass that shot the record Agg had about 10-11 firings on it, and Chad has NOT annealed the cases yet. While Chad is a very exacting reloader, he believes in the KISS principle — he doesn’t ream flash holes or uniform primer pockets. While he weighs every load with an RCBS Chargemaster, he normally does not double-check charges with a second balance. Chad tells us: “I just get the Chargemaster to where where it is going consistently and run with it.”

Chad Jenkins Aggregate IBS Record

Knowing that gun-handling and barrel maintenance are key elements of accuracy, we asked Chad about his shooting style, rest set-up, and his cleaning regimen:

Shooting style: “I try not to touch the gun, except with my thumb on the back of the triggerguard, and my index finger on the trigger. I use just a slight amount of pressure as the finger pulls the trigger. I don’t have any pressure on my shoulder. The buttplate is just barely touching my shirt.”

Rest position: “I usually let the gun run out to the stop. But there’s not much overhang. It hangs over an inch and a half. That’s where I always shot it. In the rear the ears are pretty much centered on the underside of the buttstock.”

Cleaning: “I use Montana X-Treme with patches and bronze brushes, and I clean every 35-45 rounds. I don’t brush a lot — I kind of go on feel, anywhere from 4-10 strokes. The gun shoots so incredibly well, I want to baby it, so I try not to over-clean.”

View Chad Jenkins’ Four (4) Targets

Common Sense Tips for New Shooters
Chad offered some advice for shooters starting out in the 600-Yard Benchrest game:

Reloading — I don’t claim to be an expert. But I will say that consistency is all-important. I learned this first from my friend Lewis Winkler (who passed away), and then James Coffey. Lewis always told me that the main thing is that you must be consistent in everything — when you’re sizing, when you’re weighing, when you’re seating bullets. You can’t be deviating and expect your loads to shoot.

Mental Game — I don’t go to a match to beat anybody, or to compete against anyone in particular. I shoot the best I can shoot and let the chips fall where they may. Even in practice, I basically compete against myself and I try to do the same thing in a match.

Focus (when to have it and when to relax) — I do try to stay focused when I’m shooting. But I also try to get away from the pressure between relays. A lot of the guys spend 15-20 minutes looking at everybody’s targets. I just look at my own targets and go back and sit down and relax. I don’t try to overthink things. When I was a teenager I was a successful competitive golfer. And in those days, I didn’t think about it … I just stepped up to the ball and hit it. I think, with some competitive activities, “thinking too much” can probably mess you up more than it helps.

Chad Jenkins Sets IBS 600-Yard LG Record with 1.495″ Aggregate

Piedmont Gun Club RutherfordtonThe regular, monthly 600-yard benchrest match at the Piedmont Gun Club in Rutherfordton, NC rivals a National event in terms of the quality of the shooters and the rifles. And just yesterday, a pending new IBS 600-yard, four-target Light Gun Group Aggregate Record was shot. Chad Jenkins put together a stunning 1.495″ Aggregate shooting a Light Gun with Shehane Tracker stock and Krieger barrel. Chad’s smallest group was a 1.033″. The caliber was a ‘Plain Jane’ 6mmBR. Chad’s 1.495″ Agg breaks the existing 1.6068″ record set by Sam Hall in 2011.

Sam Hall reports: “Congratulations goes out to Chad Jenkins today at Piedmont Gun Range, Rutherfordton, NC. Chad shot a 1.495″ four-target aggregate in LG this morning! The old record (1.6068″) was shot by yours truly last July. That is some kind of great shooting! Chad has been shooting great and kicking our tails for two years now. You will probabbly be hearing more from him. What I know is: he was shooting 105gr Berger VLDs (with Varget and CCI Primers) in a standard 6BR, with BAT action, ST-1000 stock, and 1:8″-twist Krieger barrel. I think it is safe to say it is a ‘hummer’!”

Mousel Breaks 1K Multi-Match Records At Missoula, Montana

Tom Mousel of Kalispell, Montana, has set two new multi-match Aggregate 1000-yard World Records. Shooting at the Deep Creek Range in Missoula, Montana, Mousel set a new 10-Match Light Gun World Record with a 5.8954″ Aggregate. That’s an average group under 6 inches for 10 matches! Mousel also set a new Light Gun 6-Match World Record with a 4.8813″ Aggregate. That 4.8813″ Agg bettered the existing 5.251″ Light Gun 6-Match Record Agg set by Mousel himself last season (2009). Congratulations to Tom for a lot of hard work and some real fine shooting! Tom set these Aggregate records over the course of the 2010 season of the Montana NW 1000-yard Benchrest Club, which is affiliated with the Original Pennsylvania 1000 Yard Benchrest Club (Williamsport).

Tom Mousel Dasher 1000 yard records

Tom’s record-breaking Light Gun is chambered as a 6mm Dasher (see photo above), which is an “improved” version of the 6mmBR Norma case. Tom uses a Stiller drop-port (bottom-eject) Viper action, set up in a Shehane laminated Tracker stock. Duane Capehart, who competes with Tom at the Deep Creek range, says that bottom-eject action helps Tom “shoot like a house on fire. Tom can get all ten shots off in under 25 seconds. He’s speedy, that’s for sure.” The barrel is a Krieger 1:8″ twist, 4 groove with about 1200 rounds through it so far. Tom has at least 12 firings on his Lapua cases, which he anneals every 3-4 firings with a Bench-Source annealing machine. He currently shoots Berger 105gr VLDs, pushed by a stout load of H4895, with CCI 400 primers. Over the course of the season he has chased the lands to maintain a seating depth about .003-.009 off the lands. Tom explains: “Seating depth is very critical with the VLDs. A few thousandths can make the difference between a fat ugly group, and something to brag about.”

Tom Mousel Dasher 1000 yard records

Noted stock-maker and past 1000-yard Shooter of the Year Bill Shehane observed: “If I am not mistaken, [Mousel’s 10-match Agg] is better than the existing Heavy Gun 10-shot Aggregate group records. I don’t think you or I will live long enough to see either of Tom’s records broken. Think about it — 10 matches over 10 different days in extremely different conditions. That’s 100 shots in under six inches. That’s remarkable for any gun — much less a Light Gun. A 6-match or 10-match Agg is never a fluke. This is an Aggregate record we may never see the likes of again. Tom’s a modest guy and someone needs to give him some credit. I’ve been at this game a long time and know the effort one has to make to accomplish something like this.”

Annual 1000-Yard Championship In August
Missoula Montana rangeIf you want to compete with Tom Mousel and the whole Deep Creek gang, head up to Missoula in August. The Montana NW 1000-yard Benchrest Club will host its 1000-yard Championship Shoot on August 13, 14 and 15. The Montana Club’s current rules allow IBS and NBRSA guns in the 17-lb and Heavy Gun Classes. In addition there is an 11-lb Sporter class. All guns shoot 10-shot groups at 1000 yards.

Entry fees are $30 per gun, per day. Camping is available at the Deep Creek range, and there will be a Catfish Fry on Friday and a Steak Dinner on Sunday after the last match. Tom says: “Come to Montana and shoot with us. We have over $16,000 worth of prizes this year.” For more info, or to request entry forms, contact Tom Mousel at 406-450-0917, or Pat Capehart at 406-821-3737.

Triumph in Texas: Jackie Schmidt Shoots 0.1118 5-Target Agg at 100 yards with 30 BR — Best in History

Jackie SchmidtTexan Jackie Schmidt, using a 13.5-lb 30BR Heavy Varmint rifle, has shot a pending NBRSA world record 5-target, 5-shot-per-target Aggregate at 100 yards. Jackie’s 5x5x100 Agg measured 0.1118! How small is that? To help our readers visualize this, the illustration at right shows what a SINGLE 0.111″ 5-shot group (with .30-cal holes) would look like. Jackie’s actual measured group sizes for his five-target Aggregate were: .153, .093, .120, .100, and .093.

If this record is certified, it will be the best 5×5 100-yard Agg ever shot in history by a bag gun in competition. Jackie’s Agg may also beat the “Unlimited” (Rail Gun) 5x5x100 records, but we’re still researching that. Remarkably, Jackie shot his 0.1118″ Agg with a stout-recoiling 30 BR (not a PPC), he did it in howling winds, and he did it with brass that had been fired 30 times! He also shot the entire Agg without cleaning his barrel.

We know it may be difficult for some readers to understand how hard it is to average 0.1118 for 25 shots on FIVE targets. To help demonstrate this, we’ve created an illustration that shows a SINGLE 0.111″ five-shot group. Jackie shot five groups that averaged this size. And he wasn’t “machine-gunning”. He took 6-7 minutes to shoot each target, firing on a “angle transition” in the conditions. Jackie explained: “The wind was switching, but I wasn’t shooting the dominant condition. I would wait for the transition and then shoot when the flags came around to about 15 degrees.”

Jackie gave credit to his rifle: “Though I usually use this rifle for score shoots, this 30BR is the most accurate rifle I have in terms of shooting small groups. I was lucky and hit the perfect tune. There was absolutely no vertical. You can’t shoot [an Agg] like this unless you have a rifle tuned to the hilt.” Jackie recognizes that this performance was a “once in a lifetime type experience.” He told us: “Today everything was right. The rifle was shooting impeccably, I had a good handle on the conditions, and just didn’t make a mistake.” Jackie added: “These days are few and far between — you just have to cherish the moment.”

Jackie’s 5-target Agg was so good that many experts predict it will stand as a record for a long time. On Benchrest Central, respected BR gunsmith Mike Bryant wrote: “The current record … was still Rex Reneau’s .1399 Agg from 1982. With Jackie’s Agg, I’m sure that it will easily beat Rex’s record when measured by the records committee. It’s just too far under the current record for it not to hold up… [and] to do it with a .30 BR is even more amazing. That should put to rest the notion that the .30 BR is a score cartridge only.”

Many people are surprised this pending Agg record was shot with a 30BR rather than a 6 PPC. When asked if he thinks the 30 BR can rival the 6PPC in group competition, Jackie told us: “In the 13.5-lb Heavy Varmint class, a good 30 BR is every bit as accurate as a good PPC, and possesses an equal Agging capability.” It’s different in the 10.5 classes, Jackie acknowledged: “in the LV/Sporter 10.5-lb classes, the 30 BR can get a little aggravating over the course of a match due to its greater recoil.”

Jackie’s Aggregate May Be Best in Benchrest History
Shooting in a Midland, Texas BR for group match, Jackie battled shifty, 15-20 mph winds in what may well be the greatest single-day display of “pure accuracy” in the history of the shooting sports. To put this accomplishment in perspective, Jackie’s 5-target Agg was better than any other 5×5 100-yard Aggregate ever shot in a registered benchrest match by a bag-gun. And according to the published records we could find on file with the NBRSA and IBS, Jackie’s 0.1118″ also beats even the existing rail-gun 5x5x100 Aggs. So, this could potentially be the smallest 5-target Agg ever shot in history, by any gun, in any registered match, at any time. Below are the current IBS and NBRSA World records listed on the Internet:

Sporter: .1592″ R. Boop 8/13/08

Jackie SchmidtGun Specs: Jackie was shooting a 13.5-lb 30 BR that he chambered and assembled himself. The barrel is a 4-groove, 1:18″ twist, HV-taper Krieger, fitted with a 5.5-oz. “snubber” barrel tuner made by Jackie. The action is a cast Farley, “glued and screwed” into the stock and fitted with a Jewell trigger. The stock is a Robertson Composites BRX, built with extra weight to make the gun a dedicated 13.5-pounder. The scope is a 50-power March.

Record Load: Jackie was running a stout load of Hodgdon H4198 powder, Federal 205M primers, and BIB (Robinette) 112gr flat-base bullets seated about .003″ into the lands. Load is “tuned for 3020 fps”. Cases are formed from Lapua 6mmBR brass using a dedicated forming barrel that blows the necks out to 0.330″ in one step. Trim length is 1.540″, longer than most 30 BRs. Jackie turns the necks for a total of .002″ clearance.
