Forum member Keith W. (aka “Cigarcop”) of KW Precision LLC is a talented riflesmith whose projects display outstanding finish work and attention to detail. Keith does some of the best bedding work we’ve ever seen. Back in 2018, Keith built a stunning F-Class rig for a shooter in Delaware. It’s a beauty, that’s for sure. Keith has posted more details about this rifle in a Shooters’ Forum Thread.
This handsome rifle features a polished Stolle (Kelbly) Panda Action, and two (2) Brux barrels, both chambered for the .284 Winchester cartridge. The real eye-catching component of this rifle is the stunning Cerus F-Open stock. This features multiple laminations with highly-figured Walnut on the sides. This certainly ain’t your “off-the-shelf” laminated stock. This just shows the beauty that can be achieved with carefully-chosen lamination layers (plus 12 coats of clear).
This beautiful F-Open rig features a laminated wood stock with stunning figured walnut on the outside.
Keith of KW Precision LLC is renowned for his bedding work, and this rifle shows why. Keith takes great pride in his work, and his attention to detail is second to none. This bedding job is as good as it gets.
Bringing out the figure in the wood requires multiple finish coats (and careful sanding between coats). But the results are worth it. Shown below is the Cerus stock, BEFORE the finish coats were applied. It took time and effort to transform the “naked” Cerus stock into a true stunner. Keith applied twelve (12) coats of PPG Automotive Clear with wet sanding between each coat.
And Another Beauty — This One Built for Capstone’s Boss
CigarCop recently completed a handsome rifle for Bill Gravatt, President of the Capstone Precision Group, distributor for Berger, Lapua, Vihtavuori, and SK products. This F-TR rig is another example of beautiful craftsmanship. Look at that bedding job in the lower photo! To learn more about this rifle, which features a black Borden Rimrock BRM action (with fluted bolt), read this Shooters’ Forum Thread.
Believe it or not, this is the first stock Brett M. carved by hand. We’d say he did a darn good job!
AccurateShooter Forum member Brett M. from Minnesota (aka Spitfire_er) recently completed a handsome laminated maple gunstock. This beauty wasn’t produced with a stock duplicator. It was made the old-fashioned way — by hand. After laminating three sections, Brett carved the complete stock with hand tools. You can see the entire carving process, start to finish, in Brett’s time lapse video.
MUST-SEE time-lapse carving video. Every second is one minute in real time. This 15:54 video shows 15.9 hours of carving! Brett says the whole job took nearly 20 hours:
Handsome Maple Blank Was Lumber Yard Return!
Brett reports: “Here’s a stock I carved up over the past year or so. I found this wood as a return at a lumber yard about 7-8 years ago. I asked the guy in the yard about it and he said it had been returned because it had too much figure for the job the customer was working on. First thing I thought was “That would make a nice stock!” I finally got around to finishing it a couple months ago.
I fit it around a 1917 Enfield in .338 WM that I purchased a while back. I usually do all the work on the receiver and barrel, but this one was done up in an OK fashion already.
This stock was almost completely made using hand tools over the course of about a year. This is a piece of laminated 1x8x1″ maple that was glued together. After it sat for about eight years, I finally got around to carving it up. This stock design/shape was from my own ideas and was carved as I went along. It turned out pretty good.”
There’s a great new way to apply an eye-catching finish to fiberglass and synthetic stocks. Water Transfer Printing (aka Hydro-Dipping) can apply beautiful, stylized patterns to your stock, and the process costs less than a custom paint job. Hydro-dipping is ideal for applying amazing photo-realistic effects such as stone, wood burl, snakeskin, or faux carbon fiber. Hydro-dipping requires no harsh chemicals or high heat so there are no negative side effects. You just end up with an amazing, patterned finish on your stock.
Hundreds of different patterns are available. We like the carbon-look finish on benchrest guns and the snakeskin patterns on hunting and varmint rifles. Natural snakeskin designs, in this Editor’s opinion, are perhaps the most effective camouflage for the largely arrid backcountry in the American southwest.
Hydro-Dip of Idaho Does Great Work
While there are a half-dozen companies offering water transfer printing for rifle stocks, Forum member Francis B. recommends Hydro-Dip, LLC of Meridian, Idaho. Examples of Hydro-Dip’s work are shown above. Francis writes: “Scott, Adam, and old man Rod Springer own and run Hydro-Dip. This is a company that will ‘paint’ your rifle, tool box, trailer, airplane, whatever and will do an excellent job while doing it. Check out their archives of jobs done. You will be amazed. I’ve not had one of their jobs done for any of mine (yet) but I’m considering it. Those who have had their rifles done tell me the cost is very reasonable. I have seen a few stocks done and they are works of art.”
Hydro-dipping (water transfer printing) can be performed on virtually any metal or plastic surface. You can Hydro-dip car parts, archery gear, rifle stocks — you name it. Watch the process in the video:
Buell’s Beast with Massive 35 Inch Barrel
A few seasons back, Our friend Darrell Buell built a new Beast — a monster 64-inch-long .375 CheyTac that weighs more than 70 pounds! Designed for ultra-long-range shooting (two miles and beyond), this beast represents the state-of-the-art in extreme long-range rifles. NOTE: to see more details, click the two images above to open Full-Screen Photos.
Darrell reports: “This rifle is pretty much purpose-built to shoot 2+ miles extremely accurately. It is a .375 CheyTac (lengthened) built on a BAT 2.5″ action. The custom 35″, 1:10″-twist Brux barrel is a fat, 2″-diameter ‘straight taper’ with fluting. A custom 5″-long muzzle brake is fitted at the end. All barreled action work was done by R.W. Snyder Custom Rifles. The stock was created to fit the build by PDC Custom, and the massive muzzle brake as well.” The “bridge” at the end may look like a barrel block, but it’s not — the barrel completely free-floats. (The Picatinny rail on top of the bridge allows use of an overhanging bipod as an alternative to the JoyPod).
Darrell has lots of elevation on tap: “With 150 MOA in the Ivey rings, another 20 MOA in the scope rail, 55 MOA in the Nightforce Competition scope, and 10 MOA in the FCR-1 reticle, there’s an impressive +235 MOA available.”
Counter-Weighted SEB Joy-Pod Up Front
The bipod Darrell will be using for his ELR sessions and the ‘King of 2 Miles’ match is a custom counter-weighted JoyPod crafted by Seb Lambang. With the counter-weight, Darrell says his monster 70-lb gun “adjusts as smoothly as an F-T/R rig”. The glass is a Nightforce 15-55x52mm Competition scope carried in Ivey +150 MOA rings, which in turn are mounted to a +20 MOA BAT scope rail. Darrell says: “It’s been a heck of a couple months, getting this monster built in time, thanks particularly to Southern Cerakote, which turned it around in less than 24 hours.”
Buell’s Beast runs 350gr solid bullets at approximately 3250 fps. Check out the massive .375 CheyTac cartridge compared to a .308 Winchester:
This one-of-a-kind “JoyPod” was produced by Seb Lambang specifically for Buell’s big .375 CheyTac rifle. Darrell needed a JoyPod that wouldn’t sink under a heavy load. Seb explains: “This is the world’s first JoyPod equipped with an adjustable counterweight, to balance his 75-lb gun. I did some experiments and put some weights ranging up to 60+ lbs on the top, and I found that the joystick action works like a regular one….it’s smooth, light, and precise. In addition, the counterweight can be bent down to not interfere with the bottom of the barrel. The counterweight is secured into the front center shaft by a thumb screw, and there is a tightly fitted pivotal joint on the counterweight to allow angle adjustment.”
Darrell is happy with his customized coaxial bipod: “In addition to the adjustable counterweight system on the front, this JoyPod comes with a longer, solid joystick. These additions will make for extremely smooth, precise adjustments, even if the rifle weighs in at 75 pounds or more. Not including the counterweight, the actual structure of this bipod weighs in at a mere 1.09 pounds — exactly what the standard JoyPod weighs. It is extremely strong, however. Seb has pictures of himself standing on the pod … and he weighs 150 pounds!”
This illustration shows headspace measurement for the popular .308 Winchester cartridge, which headspaces on the shoulder. Image copyright 2015 Ultimate Reloader.
In this Brownells Tech Tip, Brownells gun tech Steve Ostrem explains what headspace is and why it’s one of the most critical measurements for nearly all firearms. Even if you’re an experienced rifle shooter, it’s worth watching this video to refresh your understanding of headspace measurements, and the correct use of “GO” and “NO-GO” gauges.
Headspace Definition
In firearms, headspace is the distance measured from the part of the chamber that stops forward motion of the cartridge (the datum reference) to the face of the bolt. Used as a verb, headspace refers to the interference created between this part of the chamber and the feature of the cartridge that achieves the correct positioning. Different cartridges have their datum lines in different positions in relation to the cartridge. For example, 5.56x45mm NATO ammunition headspaces off the shoulder of the cartridge, whereas .303 British headspaces off the forward rim of the cartridge.
If the headspace is too short, ammunition that is in specification may not chamber correctly. If headspace is too large, the ammunition may not fit as intended or designed and the cartridge case may rupture, possibly damaging the firearm and injuring the shooter. (Source: Wikipedia)
Headspace Gauges
Headspace is measured with a set of two headspace gauges: a “Go” gauge, and a “No-Go” gauge. Headspace gauges resemble the cartridges for the chambers they are designed to headspace, and are typically made of heat-treated tool steel. Both a “Go” and a “No-Go” gauge are required for a gunsmith to headspace a firearm properly. A third gauge, the “Field” gauge, is used (as the name implies) in the field to indicate the absolute maximum safe headspace. This gauge is used because, over time, the bolt and receiver will wear, the bolt and lugs compress, and the receiver may stretch, all causing the headspace to gradually increase from the “factory specs” measured by the “Go” and “No-Go” gauges. A bolt that closes on “No-Go” but not on “Field” is close to being unsafe to fire, and may malfunction on cartridges that are slightly out of spec. (Source: Wikipedia)
To learn more, read Brownell’s longer article Headspace Gauges and How to Use Them. Among other things, this explains the relative lengths of “Go”, “No-Go”, and “Field” gauges. The “Field” is actually the longest: “The GO gauge corresponds to the SAAMI (Sporting Arms & Ammunition Manufacturer’s Institute) minimum chamber length, while the FIELD gauge usually matches the maximum chamber depth, or slightly less. NO-GO gauges are an intermediate length between minimum and maximum, that, technically, is a voluntary dimension. A firearm that closes on a NO-GO gauge and does not close on a FIELD gauge may not give good accuracy and may have very short cartridge case life from the ammunition re-loader’s standpoint.”
BAT .50 BMG Model EX– Now That’s an Action!, by GS Arizona
A few seasons ago, I stopped into Bruno Shooters Supply for a jug of powder and looked into the display case where the new actions are kept. Amid the usual array of BAT Machine, Kelbly and other actions, there was something unlike any action I’d seen before — all I can call it is the BIG BAT (It’s officially the BAT Model EX 2.5). I wasn’t too surprised at the weight (a beefy 13.7 lbs.), but until you lift it it’s hard to appreciate how solid, chunky, hefty, massive (pick your favorite adjective) this thing really is.
The action is a 2.5″-diameter, 12″-long BAT for the .50 BMG cartridge. It is simply the biggest, slickest custom action on the planet. In order to give you some sense of scale, I photographed the action alongside a conventional BAT action for short-range Benchrest shooting and I put a .220 Russian case and a .30-06 case into the picture. I’ve handled and fired other .50 BMG actions/rifles before, but this BAT puts them all to shame, as far as fit and finish go.
The action is actually quite conventional in design and execution. The bolt is fluted and has two front lugs with a conventional, although super-sized, firing pin assembly. Any Remington-style trigger will mount by way of a normal trigger hanger, allowing for simplified maintenance or replacement in the field. The loading port is 5.5″ long and the barrel threads are 1.5″ x 16 tpi — nothing about this beast is small! There is a conventional rocker-type bolt release on the left side of the receiver body and a recoil lug is built into the bottom of the receiver. In reality, the action is very similar to any other BAT except for the size and it adheres to all of BAT’s high standards for quality of design, manufacture, fit, finish and just plain good looks. Slide that bolt back and it feels as tight as a small Benchrest action!
BAT Machine states: “Our model EX is our largest action we make. It was designed to work with the .50 BMG cartridges. This action is 12.00″ long and has two exterior shape options. Starting weight is 128 oz. and varies with options chosen. This action requires a 1.75 inch diameter barrel.”
Given the BIG BAT’s $3,200.00+ sticker price (before options), not many of us will ever have the opportunity to own or shoot one of these beauties (I certainly won’t). However, it is nice to know they exist and can be bought and enjoyed in many places. CLICK HERE for BAT EX configuration options and purchase details.
We like “outside of the box” thinking. And in the world of competitive shooting, it can’t get more unconventional than this. But this radical liquid-cooled benchrest rig wasn’t just a crazy experiment — it actually delivered the goods. This IBS Heavy Gun, built by Joel Pendergraft, produced a superb 10-shot, 3.044″ group that stood as an International Benchrest Shooters (IBS) 1000-Yard Heavy Gun record for seven years, not being broken until 2016.*
Using this water-cooled wondergun, Joel shot the record-breaking group in April 2009 at Hawks Ridge, NC. This monster features a .30-Caliber 12-twist, 4-groove Krieger barrel inside a water-filled sleeve (like on a liquid-cooled machine gun). Joel shot BIB 187gr flat-based bullets in Norma brass, pushed by a “generous amount” of Alliant Reloder 25 and Federal 210M primers. The cartridge was a big custom wildcat Joel listed as “.300 Ackley Improved”. That traditionally has been based on the .300 H&H Magnum parent case**. READ Forum Thread on .300 Ackley.
This 3.044″ 10-shot group was a remarkable accomplishment, breaking one of the longest-standing, 1000-yard IBS World Records. And Joel’s 3.044″ record stood for 10 years.
This 3.048″ 10-shot group was a remarkable accomplishment, breaking one of the longest standing 1000-yard World Records. Bill Shehane commented: “This tops the NBRSA, IBS, and Original Williamsport Clubs’ all-time 10-shot Heavy Gun group records. Took a long time to do it and I for one know Joel did not back into it — he worked harder than most… to break this record. And just like John Voneida of the Original Williamsport Club who held this most prestigous record for so long, Joel is a super nice guy and a great competitor.”
Pendergraft was modest after his notable achievement: “What makes this so very special is to be able to celebrate the accomplishment with all of my shooting friends[.] A good friend once said that records are shot when preparation and opportunity meet. I feel blessed to have personally had the opportunity. The preparation we can individually work on and achieve but the opportunity only comes to a few. Those of you that compete in long range competition will know what I mean.”
*On July 24, 2016, Michael Gaizauskas shot a 2.871″ ten-shot group that bettered Pendergraft’s record by 0.171″ (less than a quarter inch). Michael’s group was also all in the 10 ring, for a perfect 100 score. CLICK HERE for IBS Long-Range Records.
** Back in 2008, the .300 Ackley was the #1 Cartridge in 1000-yard competition at Hawks Ridge. SEE Results Chart. Forum member Cheechako explains: “The .300 Ackley Magnum is actually the .300 H&H case improved. Many shooters will start with the Weatherby brass because it is higher quality. There are several versions of the Ackley but the differences are minor until you get into the few, like the 300 Hart, that actually do increase the capacity. There is also a .300 Weatherby Improved which is sort of a misnomer because it’s almost impossible to improve that case except to eliminate the rounded corners.”

4. Shooting USA — Texas Varmint Benchrest Match
This episode of Shooting USA TV features long-range varmint silhouette competition in Texas. This discipline combine the pure accuracy of benchrest competition with the fun of knocking down critter targets. These are smaller than standard silhouettes, so it’s quite a challenge to hit them at 300 yards and beyond.
In this episode, host John Scoutten competes with his 6.5 Creedmoor PRS rifle. Most shooters use benchrest-grade rifles with premium front rests. NOTE: This video shows some top-flight benchrest rifles, and also covers the origins of benchrest varmint silhouette in Pennsylvania. There are even some AccurateShooter Forum members on screen.

8. Nat’l Rifle League — Intro to NRL22 Rimfire Tactical Matches
NRL22 is a great way to get into competition shooting with minimal expense. There are Five (5) classes: Open, Base, Ladies, Young Guns (8-16), and Air Rifle. Base Class is for the budget-minded shooter — the combined MSRP of Rifle and Optic may not exceed $1050.00 (so you could spend $550 on a rifle and $500 on a scope for example). That keeps the sport affordable. Open, Youth, and Ladies Classes have no price limits on Rifle and Optic. Visit NRL22.org to find an NRL22 match near you.
In our Shooters’ Forum, one member recently asked: “What makes an AR accurate? What parts on an AR can really affect accuracy — such as free-floating handguards, barrels, bolts, bolt carriers?” He wanted an honest, well-informed answer, not just sales pitches. Robert Whitley posted a very comprehensive answer to this question, based on his experience building and testing dozens of AR-platform rifles. Robert runs AR-X Enterprises, which produces match-grade uppers for High Power competitors, tactical shooters, and varminters.
Building an Accurate AR — What is Most Important
by Robert Whitley
There are a lot of things that can be done to an AR to enhance consistent accuracy, and I use the words “consistent accuracy” because consistency is a part of it (i.e. plenty of guns will give a couple great 5-shot groups, but won’t do a very good 10- or 20-shot groups, and some guns will shoot great one day and not so good on others).
Here are 14 key things we think are important to accuracy.
1. Great Barrel: You’ll want a premium match-grade barrel, well-machined with a good crown and a match-type chambering, true to the bore and well cut. The extension threads must also be cut true to the bore, with everything true and in proper alignment.
2. Rigid Upper: A rigid, heavy-walled upper receiver aids accuracy. The typical AR upper receiver was made for a lightweight carry rifle and they stripped all the metal they could off it to make it light to carry (which is advantageous for the military). The net result are upper receivers that are so thin you can flex them with your bare hands. These flexible uppers are “strong enough” for general use, but they are not ideal for accuracy. Accuracy improves with a more rigid upper receiver.
3. True Receiver Face: We’ve found that truing the receiver face is valuable. Some may argue this point but it is always best to keep everything related to the barrel and the bore in complete alignment with the bore (i.e. barrel extension, bolt, upper receiver, carrier, etc.).
4. Barrel Extension: You should Loctite or glue the barrel extension into the upper receiver. This holds it in place all the way front to back in the upper receiver. Otherwise if there is any play (and there typically is) it just hangs on the face of the upper receiver completely dependent on the face of the upper receiver as the sole source of support for the barrel as opposed to being made more an integral part of the upper receiver by being glued-in.
5. Gas Block: You want a gas block that does not impose pointed stress on the barrel. Clamp-on types that grab all the way around the barrel are excellent. The blocks that are pinned on with tapered pins that wedge against the barrel or the slip on type of block with set screws that push up from underneath (or directly on the barrel) can deform the bore inside of the barrel and can wreck the accuracy of an otherwise great barrel.
6. Free-Float Handguard: A rigid, free-float handguard (and I emphasize the word rigid) really makes a difference. There are many types of free-float handguards and a free-float handguard is, in and of itself, a huge improvement over a non-free-float set up, but best is a rigid set-up. Some of the ones on the market are small diameter, thin and/or flexible and if you are shooting off any type of rest, bipod, front bag, etc., a rigid fore-end is best since ARs want to jump, bounce and twist when you let a shot go, as the carrier starts to begin its cycle before the bullet exits the bore.
7. Barrel Contour: You want some meat on the barrel. Between the upper receiver and the gas block don’t go real thin with a barrel (we like 1″ diameter if it’s workable weight-wise). When you touch off a round and the bullet passes the gas port, the gas system immediately starts pressuring up with a gas impulse that provides vibrations and stress on the barrel, especially between the gas block back to the receiver. A heavier barrel here dampens that. Staying a little heavier with barrel contour through the gas block area and out to the muzzle is good for the same reasons. ARs have a lot going on when you touch off a round and the gas system pressures up and the carrier starts moving (all before the bullet exits the bore) so the more things are made heavier and rigid to counteract that the better — within reason (I’m not advocating a 12-lb barrel).
8. Gas Tube Routing Clearance: You want a gas tube that runs freely through the barrel nut, through the front of the upper receiver, and through the gas key in the carrier. Ensure the gas tube is not impinged by any of them, so that it does not load the carrier in a stressed orientation. You don’t want the gas tube bound up so that when the gas tube pressures up it immediately wants to transmit more force and impulse to the barrel than would normally occur. We sometimes spend a lot of time moving the gas block with gas tube on and off new build uppers and tweaking gas tubes to get proper clearance and alignment. Most gas tubes do need a little “tweaking” to get them right — factory tubes may work OK but they typically do not function optimally without hand-fitting.
9. Gas Port Tuning: You want to avoid over-porting the gas port. Being over-gassed makes the gas system pressure up earlier and more aggressively. This causes more impulse, and increases forces and vibration affecting the top end and the barrel. Tune the gas port to give the amount of pressure needed to function properly and adequately but no more.
10. Front/Back Bolt Play: If accuracy is the game, don’t leave a lot of front/back bolt play (keep it .003″ but no more than .005″). We’ve seen factory rifles run .012″ to .015″ play, which is OK if you need to leave room for dirt and grime in a military application. However, that amount of play is not ideal for a high-accuracy AR build. A lot of front/back bolt play allows rounds to be hammered into the chamber and actually re-formed in a non-consistent way, as they are loaded into the chamber.
11. Component Quality: Use good parts from a reputable source and be wary of “gun show specials”. All parts are NOT the same. Some are good, some are not so good, and some aftermarket parts are simply bad. Don’t be afraid to use mil-spec-type carriers; by and large they are excellent for an accuracy build. Also, remember that just because a carrier says “National Match” or something else on it does not necessarily mean it’s any better. Be wary of chrome-plated parts as the chrome plating can change the parts dimensionally and can also make it hard to do hand-fitting for fit and function.
12. Upper to Lower Fit: A good upper/lower fit is helpful. For quick and dirty fit enhancement, an Accu-Wedge in the rear helps a lot. The ultimate solution is to bed the upper to a specific lower so that the upper and lower, when together, are more like one integral unit. For the upper receivers we produce, we try to get the specs as close as we can, but still fit the various lowers in the market place.
13. Muzzle Attachments: Don’t screw up the muzzle (literally). Leave as much metal on the barrel at the muzzle as you can. People like to thread the muzzle for a flash hider, suppressor, muzzle brake, or some other attachment, but if you really want accuracy, leave as much metal as you can there. And, if you have something that screws on, set it up so that it can be put on and have it stay there without putting a lot of torque and stress on it right where the bullet exits the bore. If you are going to thread the end of the barrel, make it concentric with the bore and make sure what you screw on there is as well. For all muzzle attachments, also ensure that the holes through which the bullet passes through are dead true to the bore. Many aftermarket screw-on things are not so good that way. Anything that vents gas should vent symmetrically (i.e. if it vents left, it should vent equally right, and likewise, if it vents up, it should vent down equally). Uneven venting of gas can wreck accuracy.
14. Quality Ammunition: Ammo is a whole story by itself, but loads that are too hot typically shoot poorly in an AR-15. If you want accuracy out of an AR-15, avoid overly hot loads. Shown below are test groups shot with four (4) different uppers, all with moderate loads. These four uppers all pretty much had the same features and things done to them as explained in this article, and they all shot great.
“Ultimate PPC” by Speedy with engraved Stiller Viper action. Titanium Rest by John Loh (R.I.P.).
Just in time for Christmas, today we feature a beautiful red rifle built by West Texas gunsmith Thomas “Speedy” Gonzalez many seasons back. With an eye-catching, one-of-a-kind engraved Stiller Viper action, and gorgeous red/black gelcoat finish, we think this rifle is one of the prettiest benchrest rigs ever made — and the color scheme fits the holiday season.
When Speedy set out to build the “ultimate PPC” for his own use, he wanted it to be as handsome as it was accurate. This stunning 6 PPC combines some very trick components with old-world detailing. When was the last time you saw an engraved receiver on a “race gun”? This rig combines modern high-tech components with classic good looks — the best of both worlds.
This competition benchrest rig features an engraved Stiller Viper action, with integral scope rail, SAKO Extractor and non-fluted bolt. The action sits in a new Millenium BR-X carbon-fiber stock built by Robertson Composites (now closed). The bold red-on-black marbled finish is how the gelcoat came from Ian Robertson’s factory — the stock has not been painted. The slick front rest is a titanium Ultra-Rest machined by the late, great John Loh with design input by Speedy. John built only two of these in titanium, one for himself and one for Speedy. We’re sad to say John recently passed. R.I.P. John. The Leupold Competition scope sits in quad-screw bedded rings from S.G.& Y. Precision Rifles.
Speedy picked a very special barrel for this project–a 1:14 twist, 20.5″, 6-groove barrel, the last original Pat McMillan-crafted barrel in Speedy’s inventory. Speedy runs a .263″ neck. Bushing size depends on the load and the condition of his brass. Speedy’s match load is about 29.2 grains of the IMR 8208 “ThunderBird” powder (he stockpiled this great propellant years ago). Speedy feels that T-Bird may be the most user-friendly BR powder ever made: “Once you have a good load worked up with T-Bird, you can shoot it at most any location in the country, and in almost any conditions. It’s not fussy about temperatures or humidity.”
A Very Unique Viper Action, Two Years in the Making
This is no ordinary Viper action. The full engraving attracts your attention, but there are some slick “performance mods” Jerry Stiller added at Speedy’s request.
First, the action features a plain-Jane unfluted bolt, with a slight taper in the middle, a bit of a wasp-waist. Speedy prefers an unfluted design because it has superior wear characteristics. He’s found, when working with an aluminum action such as the Viper, the sharp flutes on the bolt will wear the inside of the action faster. In the interest of reduced wear, Speedy also requested a smaller-sized loading/ejection port. This provides for a larger front and rear receiver ring, which enhances bolt bearing surface. More bearing surface reduces point loading for less internal wear.
We were surprised that Speedy did not order a drop port for his Viper. He explained: “I’m a bag squeezer, so I keep my forearm right where the cases would exit the drop port. I’ve used the drop ports, but given my shooting style, I prefer a conventional port.” Speedy did decide to fit the bolt with a SAKO-style extractor. He believes this is easier to tune and can contribute to accuracy. Speedy told us: “With a conventional sliding plate extractor, like you find on the Stolle actions, there can be a bit of a side push as you chamber the round. I think this can affect the way the bullet enters the chamber. With the SAKO extractor there is no side-push so I can reduce the possibility of bullet misalignment.”
BR-X Stock — American Design, Canadian Craftsmanship
The BR-X carbon fiber stock represents a third-generation design. The original Millenium, built by Lee Six, was a hollow shell. This modern BR-X is carbon fiber over a foam core. In Light Varmint trim, it weighs just 1.5 pounds. Speedy tells us: “this BR-X has a low center of gravity, slight pistol grip, and the angles are really straight and true. It tracks well in the bags, and won’t lift out of the rear bag during recoil. That’s one of the purposes of the wedge-shaped rear section.”
Speedy looked at the various benchrest stocks, and, with input from Tony Boyer, he worked out a design that mirrored many of the better features of existing designs with some significant enhancements. The first thing you’ll notice is that the geometry is very uniform. The flats on the side of the fore-arm are perfectly parallel. The underside of the fore-arm is seamless and completely flat. Speedy explained “one problem we’ve seen with stocks that have a mold seam in the middle is that sometimes the two halves of the mold don’t mate perfectly. Sometimes the mold is mismatched so one side is on a different plane. That creates all kinds of handling issues. If the bottom of the stock is convex, even a little bit, you lose a lot of stability.”
Much thought went into the rear section of the stock. Speedy and Tony found that many stocks would start off tracking well, but by the end of the string they were pulling themselves out of alignment. Speedy noted that with some more conventional designs, they tended to ride up out of the rear bag after two or three shots. The BR-X works differently. It uses a wedge design, rather than a radius, so it tends to drive itself down into the bag on recoil. The BR-X is not the only stock to use a wedge in the rear, but it is different than other wedge designs. According to Speedy: “On most other wedge stocks, the wedge tapers towards the pistol grip, making the ‘V’ wider towards the end of the buttstock. This will change point of aim as the stock moves. The BR-X has a wedge that is a constant ‘V’, with no taper from the end to the pistol grip. This does make the gun track better and stay on target better.”
Competition Benchrest Terminology
Bughole: Very small group.
Mothball: The 10-ring on the standard Benchrest Target.
Tomato Stake: A worn out or otherwise inaccurate rifle barrel.
Screamer: A group measuring less than 0.100″ at 100 yards or less than 0.250” at 200 yards.
Weather Report: A Group “scattered” as a result of poor wind doping.
Wailing Wall: Place where targets that have been scored can be viewed by competitors.
Dope the Wind: Ccompensate for the effects of wind by shifting aiming points on the target.
Barrels–The Hunt for a ‘Hummer’
Top 6 PPC competitors often run through a number of barrels in the quest for a “hummer” that performs optimally. In addition to the Pat McMillen tube on this gun, Speedy uses barrels from Hart, Krieger, and Shilen. He’s tried a few from some other boutique barrel makers and they shot well, but he wasn’t satisfied with the barrel life. Some of them lost their competitive edge after just 500-600 rounds. He won’t name names in print, but you can call and ask. When choosing a barrel, Speedy recommends that you invest the time and call a few well-known smiths who regularly compete in high-level BR matches. Find out what’s working real well currently.
Speedy says, “you can read the equipment lists from the big shoots, but the printed results can be deceiving. That winning barrel might have been produced a couple of years ago. Barrel-makers do have good runs and not-so-good runs. Do your homework and find out what’s working best right now.” Speedy prefers 6-groove barrels: “I’ve shot em all one time or another. It seems that the 6-groove barrels are easier to get to shoot. It seems at 200 yards bullets from a 4-groove barrel move more than from a 6-groove barrel. Both windage and elevation. I think Tony Boyer feels the same way.” [Editor’s Note: Speedy’s groove observations were made many seasons ago. Today, many top shooters are using 4-groove and 5-groove barrels, and 3-grooves have been successful in score competition.]
We asked about Speedy’s signature “SpiderWeb finish”. While the web design has esthetic appeal, there is a functional side as well: “Tests have shown that a bead-blasted barrel will shed heat faster than a highly polished barrel. With the SpiderWeb, we leave most of the bead-blast finish on the barrel, but the web effect gives the tube some visual appeal.”
Speedy Speaks — How to Succeed in Benchrest Competition
Let me begin by saying that benchrest competition is the most difficult sport I’ve ever tried. For the newcomer, it can be daunting. From the very word “go” you are thrown to the wolves. Most new competitors have about a two and a half or three-year window. After that, if they are not meeting their expectations, they get fed up and leave the sport. Considering the time, effort, and money they may have expended in that time, that’s an unfortunate outcome.
So, how does one improve as a shooter and get to the point where you are meeting your goals? First you need to break down the shooting process into its parts–gun handling, loading technique, wind awareness, time management, bag set-up, and what I call ‘bench management’. Then you need a mentor. Benchrest is like golf–you can have the best equipment (best action, best stock, best rest) but you won’t get far without a knowledgeable veteran to monitor your progress and observe your technique. Without a mentor, benchrest is a rough game to play and you can reach a frustration point after a couple of years.
If you don’t have somebody who can sit and evaluate your loading style, bolt-working, follow-through, and wind-reading etc., you can develop bad habits that are hard to break. If there’s no one to monitor your shooting and see what you’re doing wrong, you’ll keep making the same mistakes. So how does one find a mentor? Well it’s not a bad idea to attend one of the shooting schools. But one-on-one training is best. Look for someone with a strong record in competition, but a person who is also patient. And when you find that person, show some loyalty. With most people who have been involved in the sport a while, if you show them allegiance, they will return that allegiance.
6mm PPC Basics — About the Cartridge
Developed by Louis Palmisano and Ferris Pindell (left and right in photo), the 6 PPC is the “King of the Hill” in short-range benchrest competition, the most accurate cartridge ever invented. It still completely dominates 100- and 200-yard Group BR Shooting. If you want to win in that game, you pretty much have to shoot a 6 PPC, or some close variant of the 6 PPC cartridge design.
Easily made from Lapua 220 Russian brass, the 6mm PPC has a small primer and small flash hole. The small flash hole/primer accounts for much of the 6 PPC’s superior accuracy, though nobody really knows precisely how or why. The “short, fat” shape and nearly straight body contribute to efficient, consistent combustion and good “chamber behavior”.
While SAKO has created an official SAAMI 6mm PPC round, called the 6PPC USA, most American 6 PPC shooters run tight match chambers cut with custom reamers. There will be variations from one reamer to another, enough so that custom dies are generally recommended for match guns. Here is a PT&G reamer spec’d by Speedy a while back. He prefers a .263″ neck because that works better than .262″ when he needs to use his tightest bushings to get more neck tension.
The 6 PPC’s case capacity, case size to bore ratio, and combustion properties seem to be just about ideal for the short 6mm match bullets. A 6BR can come close, but when the goal is shooting “zero” groups at 100 and 200 yards, the 6 PPC is the clear winner. Currently most 6 PPC shooters form their cases from Lapua 220 Russian brass. Norma also makes factory-formed 6 PPC cases, but Norma brass is not commonly used as most shooters believe it is less “tough” than Lapua brass and accordingly won’t last as long with very stout match loads.
Handsome Maple Blank Was Lumber Yard Return!
Headspace Gauges
This 3.048″ 10-shot group was a remarkable accomplishment, breaking one of the longest standing 1000-yard World Records. Bill Shehane commented: “This tops the NBRSA, IBS, and Original Williamsport Clubs’ all-time 10-shot Heavy Gun group records. Took a long time to do it and I for one know Joel did not back into it — he worked harder than most… to break this record. And just like John Voneida of the Original Williamsport Club who held this most prestigous record for so long, Joel is a super nice guy and a great competitor.”
This episode of Shooting USA TV features long-range varmint silhouette competition in Texas. This discipline combine the pure accuracy of benchrest competition with the fun of knocking down critter targets. These are smaller than standard silhouettes, so it’s quite a challenge to hit them at 300 yards and beyond.
5. Gas Block: You want a gas block that does not impose pointed stress on the barrel. Clamp-on types that grab all the way around the barrel are excellent. The blocks that are pinned on with tapered pins that wedge against the barrel or the slip on type of block with set screws that push up from underneath (or directly on the barrel) can deform the bore inside of the barrel and can wreck the accuracy of an otherwise great barrel.
Just in time for Christmas, today we feature a beautiful red rifle built by West Texas gunsmith Thomas “Speedy” Gonzalez many seasons back. With an eye-catching, one-of-a-kind engraved Stiller Viper action, and gorgeous red/black gelcoat finish, we think this rifle is one of the prettiest benchrest rigs ever made — and the color scheme fits the holiday season.
First, the action features a plain-Jane unfluted bolt, with a slight taper in the middle, a bit of a wasp-waist. Speedy prefers an unfluted design because it has superior wear characteristics. He’s found, when working with an aluminum action such as the Viper, the sharp flutes on the bolt will wear the inside of the action faster. In the interest of reduced wear, Speedy also requested a smaller-sized loading/ejection port. This provides for a larger front and rear receiver ring, which enhances bolt bearing surface. More bearing surface reduces point loading for less internal wear.
Much thought went into the rear section of the stock. Speedy and Tony found that many stocks would start off tracking well, but by the end of the string they were pulling themselves out of alignment. Speedy noted that with some more conventional designs, they tended to ride up out of the rear bag after two or three shots. The BR-X works differently. It uses a wedge design, rather than a radius, so it tends to drive itself down into the bag on recoil. The BR-X is not the only stock to use a wedge in the rear, but it is different than other wedge designs. According to Speedy: “On most other wedge stocks, the wedge tapers towards the pistol grip, making the ‘V’ wider towards the end of the buttstock. This will change point of aim as the stock moves. The BR-X has a wedge that is a constant ‘V’, with no taper from the end to the pistol grip. This does make the gun track better and stay on target better.”
