Over the years, many different concentricity tools have been on the market. Various approaches have been taken to straightening rounds that exhibit poor concentricity. With extreme examples of excessive run-out, the bullet is is visibly crooked in the neck with the bullet tip clearly off-center. That’s never a good thing. Straight ammo shoots better.
Straighten-Up and Fly Right
If you could straighten up crooked rounds, accuracy should be improved. In the past, some tools promised more than they delivered. But now Bill Goad, a record-setting benchrest shooter, has invented a new tool that improves concentricity via an impact or “jarring” method. A vertical rod with a curved face mates with the case-neck. You spin the case to find the “high spot” of max eccentricity. Then just tap the rod a couple of times and the neck comes back onto centerline. You can then confirm the concentricity improvement with the dial indicator. Watch the video to see how this is done. Pay particular attention to times 01:25 to 01:45. The case starts at .004″ run-out (01:32). After correction (01:40) the neck shows less than .001″ (one-thousandth) run-out.
Bill Goad knows something about accuracy. He shot a 10-target 100/200 benchrest Combined Aggregate of 0.178″ (see video at 00:15-00:35). Bill Goad’s tool offers advantages over systems that clamp a cartridge at both ends and try to bend the case or tilt the bullet without straightening the neck. Goad’s new Fli-Right tool is available now from PremierAccuracy.com.

The Original Pennsylvania 1000-Yard Club (Williamsport) is now accepting applications for its 2015 Long-Range Benchrest School. If you want to learn how to shoot accurately at very long range, one of the very best places to learn is the Williamsport 1000-Yard Benchrest School. The 8th Annual Benchrest School will be held Friday, June 5 through Sunday, June 7, 2015. Classes, taught by top 1K shooters, are held at the Williamsport Range, one of the best 1K ranges in the country.
From June 5-7 2015, the club will host a multi-day, long-range Benchrest Academy for novice to intermediate shooters. For $350 students will enjoy 1 night and 2 days of intensive training under the guidance of top 1000-yard shooters. Prospective students will be taught all aspects of long-range benchrest shooting by highly skilled instructors. All areas are covered: load development, precision reloading, bench skills, and target analysis. Much time is spent at the loading bench and on the firing line. And you don’t even need guns and ammo — all equipment and ammunition will be provided. The sign-up deadline is June 1st. To reserve a spot, email School Director/President Ryan Miller: ryanmiller @ htva.net.
School Schedule, Friday Through Sunday
On Friday night (June 5th), students will meet their mentors. Saturday (June 6th), the class moves to the range for a full day of hands-on technical training. Topics will include precision reloading, load development, gun handling, use of chronograph, analysis of shooting results, gun cleaning, and target analysis. The club will provide the rifles and all reloading components. Saturday’s training sessions are followed by a steak dinner which is included in the $350 seminar price.
On Sunday (June 7th), after an early training session covering bench set-up and match strategies, students will participate in a 1000-yard match, spending time both behind the trigger and in the pits. Instructors will explain how to read conditions, and will demonstrate target measuring and analysis after the relays. The program wraps up by 4:00 pm on Sunday.
To see what the 1K Benchrest school is like, watch the slide show/video below, produced by Sebastian Reist, an alumnus of the 2009 Williamsport 1000-yard BR school.

Low-BC bullets launched from a .22 LR gun are easily blown around by the wind. That’s why it’s a smallbore shooter’s dream to shoot indoors, where fickle wind currents are less likely to spoil your shots. Not many folks have the opportunity to shoot indoors at all, must less compete in an indoor match. However, a crew from Ashbury Precision Ordnance recently got the chance to try out their rimfire rifles in a indoor setting, a converted poultry barn to be precise. And today they’ll be competing in a smallbore “Barn Benchrest” match at that same barn. Looks like fun!
Could this be the beginning of a new “Barn Benchrest” league? The folks at Ashbury tell us: “Rube, Gary, and Matt headed over the mountains to Luray, Virginia, to get in some practice for [Saturday’s] .22 Cal Benchrest Rifle Match. It’s colder than a well diggers’ butt outdoors, but shooting a match indoors, in a converted poultry barn, is nice. As always, we’re shooting great RUAG/RWS ammo!”
Poultry Barn aka Piney Hill Benchrest Facility
The official name of this converted barn is the Piney Hill Benchrest facility. Virginia State 3-Gun Rimfire BR Championships will be held there February 20-21, 2015, while the IR50/50 Indoor Sporter Nationals are scheduled for Piney Hill in March. If you’re curious, the benches are made from cement blocks with wood tops, so they’re very solid. Here’s a panorama photo of the Piney Hill Barn.

Shooting reactive targets is fun, especially when you get to use ultra-accurate benchrest rifles. To see how the “Varmint Silhouette” game is played, tune in to Shooting USA tonight on the Outdoor Channel. Tonight’s episode features a long-range varmint benchrest silhouette match at the Ridgway Rifle Club in Pennsylvania. This is silhouette like you’ve never seen it, with targets placed from 850 to 1,000 yards, and shooters using precision rifles, high-end optics, and advanced rests. This new sport combines the knock-down fun of silhouette with the high-tech precision of benchrest shooting. At Ridgway’s first Bench Rest Silhouette match 28 shooters participated. Five years later, nearly 120 shooters attend regular monthly matches. CLICK HERE for Match Info.
Varmint Benchrest Silhouette Basics
In 2010, the Ridgway Rifle Club combined Metallic Silhouette and 1000-yard Bench Rest into one exciting new discipline. Steel targets are arrayed in banks of five at four distances. The targets are set up as follows: Crows at 850 yards, Ground Hogs at 900 yards, Bobcats at 950 yards, and Coyotes at 1000 yards. Just dinging a target is not enough — to count as a “hit”, the target must fall down.
Ridgeway allows two classes of guns, Heavy Class with a maximum weight of 17 pounds, and Standard Class with a maximum weight of 12 pounts. Both classes must otherwise conform to the Light Gun rules for the Original 1000-Yard Bench Rest Club in Williamsport, PA.
Varmint Silhouette West of the Mississipi
Clubs in other states also host Varmint Silhouette matches (or some variant thereof). One of the longest-running and most popular Varmint Silhouette matches is held the first weekend of every month at the Pala Range, in San Diego County, California. At Pala, competitors shoot at “critter” targets placed at five yardages: 200 Meters – Field Mice (“pikas”); 300 meters – Crows; 385 meters – Ground Squirrels; 500 meters – Jack Rabbits; 600 yards – Prairie Dogs
Fun Weekend for the Whole Family
At Pala, there’s a deluxe Indian Casino/Spa nearby. So don’t hesitate to bring the wife. If she’s not a shooter, she can enjoy a fancy brunch or spa treatment while you’re having fun mowing down metal critters. Pala is a 30 minutes from the Pacific Ocean and beautiful beaches, so you can make this a weekend holiday for the whole family — kids love sand and surf.

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:
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.
Here’s a simple solution for lumpy front sandbags. Cut a small block the width of your fore-end and place that in the front bag between matches. You can tap it down firmly with a rubber mallet. This will keep the front bag nice and square, without bunching up in the center. That will help your rifle track straight and true. Rick Beginski uses wood (see photo), while our friend John Southwick uses a small block of metal. The metal block might work a little better, but the wood version is easier to make with simple tools. John Loh of JJ Industries offers a slick Delrin block with a built-in bubble level. Loh’s block helps ensure that the actual top surface of your front bag is level, as distinct from the front rest assembly.

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

Here’s some benchrest advice that can help you reduce vertical and shoot tighter groups… without spending another penny. Next time you go to the range, experiment with the position of your rifle on the front rest, and try a couple different positions for the rear bag. You may find that the rifle handles much better after you’ve made a small change in the placement of your gun on the bags. Recoil can be tamed a bit, and tracking can improve significantly, if you optimize the front rest and rear bag positioning.
Balance Your Gun BEFORE You Spend Hours Tuning Loads
In the pursuit of ultimate accuracy, shooters may spend countless hours on brass prep, bullet selection, and load tuning. Yet the same shooters may pay little attention to how their gun is set-up on the bags. When you have acquired a new rifle, you should do some basic experimentation to find the optimal position for the forearm on the front rest, and the best position for the rear bag. Small changes can make a big difference.
Joel Kendrick, past IBS 600-yard Shooter of the Year, has observed that by adjusting forearm position on the front rest, he can tune out vertical. He has one carbon-fiber-reinforced stock that is extremely rigid. When it was placed with the front rest right under the very tip of the forearm, the gun tended to hop, creating vertical. By sliding the whole gun forward (with more forearm overhang ahead of the front sandbag), he was able to get the whole rig to settle down. That resulted in less vertical dispersion, and the gun tracked much better.
Likewise, the placement of the rear bag is very important. Many shooters, by default, will simply place the rear bag the same distance from the front rest with all their guns. In fact, different stocks and different calibers will NOT behave the same. By moving the rear bag forward and aft, you can adjust the rifle’s overall balance and this can improve the tracking significantly. One of our shooters had a Savage 6BR F-Class rifle. By default he had his rear bag set almost all the way at the end of the buttstock. When he slid the rear bag a couple inches forward the gun tracked much better. He immediately noticed that the gun returned to point of aim better (crosshairs would stay on target from shot to shot), AND the gun torqued (twisted) less. The difference was quite noticeable.
The important point to remember here is that each rig is different. One gun may perform best with the front rest right at the tip of the forearm (Position ‘D’ in photo), while another gun will work best with the rest positioned much further back. This Editor’s own 6BR sits in a laminated stock that is pretty flexy in the front. It shoots best with the front rest’s sandbag located a good 6″ back from the forearm tip (position ‘A’).
A small change in the position of the forearm on the front rest, or in the placement of the rear bag, can make a big difference in how your gun performs. You should experiment with the forearm placement, trying different positions on the front rest. Likewise, you can move the rear bag back and forth a few inches. Once you establish the optimal positions of front rest and rear bag, you should find that your gun tracks better and returns to battery more reliably. You may then discover that the gun shoots smaller groups, with less vertical dispersion. And all these benefits are possible without purchasing any expensive new gear.
You have to love this story, supplied by our friend Lou Murdica. It seems that a petite little 10-year-old school girl finished fourth in a 100-Yard Benchrest match in Phoenix, beating some of the best in the business, including many Benchrest Hall of Famers. That’s right, shooting a remarkable 0.1612 Aggregate, little Angelina G. put a whupping on some very big names in the Benchrest game, including Lou Murdica himself. Angelina finished just .008 behind Hall of Famer Gary Ocock, beating other Benchrest superstars such as Bob Brackney, Lester Bruno, and Tom Libby. Angelina also beat legendary bullet-maker Walt Berger, but we’ll cut Walt some slack. Now in his 80s, Walt deserves praise for doing so well at the opposite end of the age spectrum.
Congratulations to Angelina on some great shooting in the Unlimited Class. Her five groups measured: 0.186, 0.172, 0.173, 0.121, 0.155. That’s impressive consistency. You go girl!
Point to ponder: If Angelina was shooting a Rail Gun, her rifle probably weighed more than she did.

Our friend (and ace benchrest shooter) Lou Murdica recently tested some prototype Accurate LT-30 powder from Western Powders. This is a new formulation similar to LT-32, but with a slightly faster burn rate. That makes LT-30 ideal for the 30 BR and other cartridges that presently work well with Hodgdon H4198. Lou tells us: “At a 100/200-yard group benchrest match in Phoenix this weekend, I shot the new LT-30 powder in a 30BR. I used Berger 115gr bullets in a rifle with a Shilen barrel. This powder is just like the LT-32 powder… just a little faster.”
Lou added that, in the 30 BR, this powder delivers accuracy similar to Hodgdon H4198, but 30 BR loads with match bullets can be pushed up to 200 FPS faster without apparent pressure issues. That’s significant. Lou posted some targets which do indicate that LT-30 offers excellent accuracy. Here are 5-shot groups shot with Berger 115s and LT-30 powder:
Western Powders has not yet announced an “arrival date” for LT-30, so we can’t tell you when you will see LT-30 at retail powder vendors. It appears this new propellant will go into production in the near future, though LT-30 is not yet listed on the Accurate Powders website.
Accurate’s New LT-30 Powder Is Like LT-32 but a Little Bit Faster…
LT-32 is a fine-grained extruded powder that was developed for 6mm PPC benchrest competitors. Already a proven match winner, LT-32′s excellent shot-to-shot consistency and low standard deviation (SD) make this a very good choice for competitive benchrest shooting. Due to its small grain size, LT-32 flows like a spherical powder and allows for very precise hand-loading. It also offers impressive accuracy in varmint and tactical cartridges, including the .223 Rem, and 20 Tactical. If you haven’t tried LT-32 in your PPC or varmint cartridges yet, you should give it a try. LT-32 is one of the most accurate powders on the market, when used with appropriate bullet/cartridge combos.

Stiller’s Precision Firearms is now offering its new line of rear lug, benchrest-grade rimfire actions, the 2500X (single-shot) and the 2500XS (sporter class mag-fed). These actions have already performed superbly in competition (see below). These actions represent the state-of-the-art in rimfire receivers. Top rimfire benchrest shooters are building rifles around the new Stiller actions and the results have been very promising. These actions offer true benchrest-grade manufacturing tolerances plus a superior firing pin system that should allow greater shot-to-shot consistency. Expect fewer unexplained fliers with these Stiller actions compared with older, factory-based actions (such as the Rem 40X).
Stiller 2500X Rimfire Action
The 2500X is Stiller’s new rear lug rimfire benchrest action. This features an Anschutz-style loading ramp, center recoil slot, side bolt release, and a unique shroud/firing pin system for perfect alignment (and more consistent ignition). Unlike many rimfire actions, the 2500X has a trigger hanger for easy trigger maintenance. The 2500X’s body and bolt are crafted from 416R stainless steel with a nitride finish for smooth and trouble-free operation. The outside is OD ground after nitriding for precise tolerances and a distinctive two-tone look.
Stiller 2500SX Rimfire Sporter Action
The 2500XS is a rear lug rimfire benchrest action for the Sporter Class. The “XS” model features a Sako magazine and easy-to-use loading ramp. Like the 2500X, the “XS” has an advanced shroud/firing pin system, plus a trigger hanger for easy trigger maintenance. The bolt and body are nitrided, 416R stainless OD ground for a dimensionally precise, two-tone finish. This lightweight action is specifically designed for IR50/50 sporter class benchrest. It comes with one (1) magazine.
Proof of Performance — 2500X Action Shoots 250-25X
Mike Kuklis’s new rimfire BR rifle built on a Stiller 2500X action delivered an impressive 250-25X in competition last week. Mike drilled this superb 250-25X card at the Tuckertown BR Barn on the way to a 1000-86X match win. Credit J. Miller for the photos from Benchrest Central.

Story by Jaime Hammer, IBS Social Media Manager
Paul Hammer was introduced to benchrest rifle shooting by his friend Bill Adcox at the Greenville Gun Club (in Greenville, SC) about five years ago. He has been an avid skeet shooter for most of his life, but his daughter never fell in love with that sport. The first time he took her to the rifle range with him, she was hooked. She loved the precision of it and that it’s very relaxing. If you haven’t been able to tell by now, I’m his daughter. What began slowly as a fun hobby that we could enjoy together picked up speed a year and a half ago, when we went to our first IBS match, a 100/200 yard match at Piedmont Gun Club. From then on, he spent much of his free time learning about the sport, from techniques to types of guns to how to reload his own ammunition.
Paul Hammer and Daughter Jaime Enjoy Time at the Range Together…
He frequently practices or competes in both group and score matches at 100, 200, and 600 yards at Piedmont Gun Club, Polk County Gun Club, and Greenville Gun Club. This year, he even competed for the first time in the annual Groundhog and Egg Shoot in Hickory, NC hosted by Bull’s Eye Sporting Goods. His smallest group, made while practicing at 100 yards with a 6 PPC, was 0.17 inch. His best score, made at 100 yards at the NC State Championship with a 6 PPC, was 249 with 8 Xs (he commented that he “made a perfect score with 5 Xs on the sighter target!”).
He said, “For me, benchrest rifle shooting is enjoyable because there’s so much to learn, and the people you meet along the way are nice and helpful. It’s fun and challenging.” Although he always tries and wants to shoot well, at the end of the day, he just enjoys the sport, spending time with his daughter, and meeting new people.
Part of his benchrest education has come from helping plan benchrest matches for Polk County Gun Club. Last September, in conjunction with Tony Moss, Paul began organizing monthly 100/300 yard groundhog and egg shoots. In doing so, he has learned more about shooting and what it takes to put together a successful benchrest rifle match. Paul and Tony are currently working with the board of directors to improve Polk County Gun Club’s rifle range and install target backers to get approval to hold IBS matches there.
