Here is Ernie Bishop’s pride and joy, a specialty pistol nicknamed “Batman” because the black carbon-fiber stock looks like the Batmobile. This is one sophisticated handgun. Complete with scope, the Batman pistol weighs under 7.5 pounds, thanks to the ultra-light stock. The carbon stock is 6 inches wide at the fore-end, yet weighs just one pound. Ernie tells us: “This gun shoots amazing and is easy to shoot especially with my SEB MAX Rest.” After these photos were taken, Ernie added a “field-usable rear-grip stock so [he could] shoot it prone from a bipod as well.”
The Batman pistol is chambered for the 6mm “Long Dasher”, a 6mm 40°-shouldered variant of the 6.5×47 Lapua. Ernie loads Berger 105gr Hybrid bullets pushed by Hodgdon H4350 powder.
Gun Specifications The gun, crafted by Eric Wallance of Nawaka Firearms, features an XP-100 action, Jewell trigger, and 15″-long, Brux 1:8″-twist barrel with aluminum muzzle brake. Interestingly, this gun does not have a traditional recoil lug. Instead, gunsmith Wallace milled out a lug from the bottom of the XP-100 action to save weight. On top of the action, the rig carries a Sightron Inc S-III 6-24X56mm scope in Kelbly rings on a custom +20 MOA rail.
Long Dasher Wildcat
Shown at right is a “Long Dasher” 40° wildcat created by Forum member Sunbuilder. This is very similar to Ernie Bishop’s chambering, though there may be small variations related to reamer design (such as freebore). Sunbuilder’s 6-6.5×47 Improved (aka “Long Dasher”) reamer was made by Dave Kiff of Pacific, Tool & Gauge. This wildcat cartridge adds about 2.0 grains capacity to the 6.5×47 necked down to 6mm. The case certainly is impressive with that 40° shoulder. We’re just waiting for the tactical guys to starting run this improved cartridge with its original 6.5mm bore.
Here are three FIVE-shot groups at 500 yards, shot by Ernie’s Batman pistol. The first 5-shot group is marked with pink dots, the second with green dots, and the third is measured with the calipers:
All shooters, even rimfire enthusiasts, should always wear ear protection when at the range. A typical rifle gunshot is very loud — in the region of 140 to 170 decibels (the pain threshold is 130-140 db). Without ear protection, you can permanently damage your hearing during a single shooting session. We all know older shooters who are partially deaf, or who suffer from Tinnitus, because they didn’t use earplugs or muffs when they were younger.
How Humans Hear Sounds — Amazing Video Reveals All
The human sense of hearing involves multiple delicate internal membranes, bones, organs, and nerves. Shooters understand the importance of protecting their hearing, but they may not understand the bio-mechanics of human hearing. We hear sounds through Auditory Transduction. Sound waves vibrate the ear drum (tympanic membrane), but that is only the beginning. These vibrations are passed along via tiny rocker-arm-like bones to be “processed” in a spiral chamber, the cochlea.
This remarkable VIDEO explains how humans hear sounds. We strongly recommend you take the time to watch and learn. The hearing you save may be your own!

Vibrations moving through the cochlea are separated into frequencies and then sent as neural messages to the brain. It is an astonishingly complex process, one that truly seems miraculous when you examine the bio-engineering involved. In the Video above, the process of human Auditory Transduction is explained and illustrated with 3D animation. You really should watch this amazing video. By the end you will have a new-found appreciation for your ability to hear.
⏺ Dual-function electronic muffs — great for range communications
Every shooter should own a pair of Electronic muffs, even if you prefer shooting with earplugs and/or standard muffs. Electronic muffs are great when you are spotting for other shooters or are working near the firing line. They let you hear ordinary conversations while still providing vital hearing protection. You can also wear ear-plugs under muffs for extra sound attenuation.
Plugs PLUS Ear-Muffs — The Benefits of “Doubling-Up” Your Hearing Protection
According to OHS Online: “The combined attenuation of an ear plug and an ear muff is not simply the algebraic sum of the performance of each individual protector. This is due to an acoustic and vibratory interaction between the ear muff and the ear plug that causes them to behave together as a system rather than as independent hearing protectors.
Generally speaking, when you combine two hearing protectors, ear muffs over ear plugs, you can expect an increase [in noise reduction] of between 3 and 10 dB over the higher-performing hearing protector. OSHA [now advises] 5 dB as the [typical] benefit offered by combining hearing protectors.” Source: OHSonline.com
Brian Williams is one of the top CMP match shooters in the nation. At the 2021 CMP Eastern Games, Brian won both the 3-Gun and 4-Gun Aggregates. He also won the 4-Gun at the CMP National Matches in Camp Perry three years in a row — the inaugural 2017 4-Gun Agg, plus 2018 and 2019. Due to COVID, there were no CMP Camp Perry National Matches in 2020, but Brian has been a leading competitor in subsequent seasons and he’ll be at Camp Perry this summer.
Given his remarkable, consecutive “three-peat” in the CMP 4-Gun Aggregate at Camp Perry, it cannot be questioned that Brian is the leading CMP 4-Gunner in the nation. In this article, Brian provides perspectives on the “Wood Gun” game, with suggestions on how to improve your performance with the M1 Garand, M1903 Springfield, M1917 Enfield, M1 Carbine, and other 20th Century military rifles. While Brian also shoots his AR15 for the 4-Gun, today’s article focuses on his favorite firearms — his classic “Wood Rifles”.
VIDEO Showcase — Brian Williams Shoots M1903A3 Prone
The Classic Wood Guns of CMP 4-Gun Competition
Perspectives on M1 Garand, M1903A3, M1917, and M1 Carbine
Q: What should one look for when acquiring older rifles for CMP 4-Gun Games — M1 Garand, M1903/1903A3, M1917, M1 Carbine? What are realistic budgets for these firearms? What kind of accuracy can one expect? What upgrades are important?
Brian: All of these military surplus rifles are out there, but they are getting harder to get your hands on. And, just like everything else, the prices continue to rise. Not that long ago you could get your hands on a M1 Garand for four or five hundred dollars. In today’s market they are usually about double that price. But understand that these rifles are all unique and all have a story to tell. No two are alike, or have the same story. Just like the guns themselves, there are fewer and fewer dedicated gunsmiths for these vintage rifles. But I promise if you look for a good smith, they are out there and they are some of the most interesting people you will ever meet.
M1 Garand — Of the four (4) centerfire guns I shoot in the CMP games, my favorite has to be the M1 Garand. There were over 6 million of them produced in a very short time period, and every single one has its own unique story, and that is just cool. M1 Garands are capable of good accuracy. I believe that a well-maintained M1 with at least a replacement barrel is capable of shooting between 1 and 1.5 MOA.
M1903A3 Springfield — I find that the sights on a M1903A3 are a little easier to see than the sights of the M1903, but both are very accurate rifles. Like most military rifles in the current climate the prices have risen dramatically, but there are some gems out there that can be had for far less than $1000. The nice thing about the Springfield rifle is that almost all of the accuracy than you would want can come from just replacing a worn out 80-year-old barrel. In terms of accuracy, I think a good M1903A3 can shoot 1 MOA most of the time.
M1917 Enfield — This rifle is the newest of my collection and it shoots very well, with just a new Criterion barrel — again about 1 MOA with iron sights. These rifles are very close in price to the M1903 Springfield. But if you do your homework and keep your eyes open, there are always great deals to be found. I actually prefer shooting the M1917 to my M1903A3, due primarily to the M1917’s cock-on-close bolt which allows smoother cycling.
M1 Carbine — By 1945 there had been more M1 Carbines built than Garands. Today the Carbine can be harder to find, and due to the scarcity the price has shot up and most military M1 Carbines are going for more than $1000 at this point. The great thing about the M1 Carbine is that as long as you have a good ammo supply this rifle can shoot. Honest. I have had countless numbers of people that tell me that there is not an M1 carbine that will shoot. I can tell you from experience that they will, but you are going to have to put in some time with one to learn how to get it to shoot where you want it.
The M1 Carbine shoots the .30 Carbine round, with 110gr bullet going about 1990 FPS. In comparison, the .30-06 Springfield round used in the M1 Garand is almost three times more powerful than the .30 Carbine.
Reloading for .30-06 Springfield Rifles
Tech Report by Brian Williams
Reloading for a military surplus gun as different than loading for a modern precision rifle in my opinion. There are a few tasks that care over from one to the other, but the main goal is slightly different. The Target that is being shot in the CMP games matches has a rather generous 10 ring, and with a little larger target you focus needs to change from a round with ultra accuracy to a round that is safe and functions well in your particular rifle.
Bullet Selection — With the .30-06 for my Garands and Springfields I stick mostly with 168gr bullets plus some 155-grainers. These bullet weights have just worked for me in the past.
Cartridge Brass (Milsurp vs. Commercial) — I use both military and commercial brass, having success with each. I do prefer commercial brass as it is easier to prep for the first reload. Military brass usually has a primer crimp of some kind that needs to be removed, and I have found that trimming these cases can sometimes leave you scratching your head as the OAL on military cases varies considerably.
Power Charge and Dispensing — I have always had good success with Hodgdon H4895 powder. My load has always been right around 47.0 grains, with both the 168gr and 155gr bullets. I also use the Auto-Trickler to drop all of my powder charges. This is a fantastic piece of equipment that not only gives super-consistent powder charges quickly, but it also makes one less thing that you have to worry about while on the firing line. With the Auto-Trickler, there is never a question about the powder charge in your ammo. As for primers, I have been shooting CCI 200 Large Rifle primers for many years and have never had an issue.
Case Care and Trimming — With most of the .30-06 brass that I use, I will only reload them 5 times maximum. I don’t push the brass too much, because the Garand’s semi-auto cycling can be tough on the cases. I also trim my cases for OAL each reload cycle. I use a Giraud power trimmer, so trimming is relatively quick and easy.
The chambers in some of the older rifles are not perfectly-machined like a modern high-end rifle. This can cause the brass to grow a little inconsistently, so I find trimming every load cycle helps to make sure that everything stays in a nice safe spec.
Case Annealing — A few years ago I started to anneal my .223 Rem service rifle brass. Now I have added that process for all my match ammunition. I anneal after every firing. It is a rather easy step as I can have my auto-feeding Annealeez machine running while doing something else, so annealing does not add a great deal of time or effort to the reloading process.
The .30-06 case was the father of the .308 Winchester, which was adopted as the 7.62×51 NATO cartridge. Brian has another Garand chambered in .308 Win which he shoots in Service Rifle Class in the President’s Match and NTI Match at Camp Perry.
Perspective on CMP 4-Gun (and 3-Gun) Aggregate Competition
Since the CMP’s introduction of the 4-Gun Aggregate in 2017, combining three classic wood rifles with the modern AR15-platform guns, Brian has lead the field, winning the 4-Gun at every National Match cycle held so far by the CMP at Camp Perry. Brian has also dominated in the 3-Gun Aggregate which includes the three older wood rifles.
Q. What’s the most fun/satisfying thing about shooting CMP 4-Gun Aggs?
Brian: The 4-Gun Agg takes place over several days, and is usually decided by a very thin margin of victory. Making sure that you are prepared for all four rifles and keeping focus through several days of competition is very difficult. There is a great sense of accomplishment when you are able to perform well for the entire aggregate.
Q. Do you like shooting the wood rifles more or the AR in Modern Military?
Brian: No question that the wood rifles are my favorite. A steel rifle, with a beautiful wood stock (see above), firing the .30-06 Springfield, is “where it is all at” in my opinion.
Q. What is the best approach to shooting these older Wood Guns?
Brian: One of the things that I struggled with shooting the “wood guns” is that it is so easy to tell yourself that its the rifle and not your bad habits or poor position. “The rifle is far older than I am it must just not be a shooter”. In order to be successful with these rifles you have to be honest with yourself. Only then will you improve.
Q. If you could change any CMP 4-Gun course of fire, or revise aspects of the CMP 4-Gun discipline, what would you modify/alter?
Brian: There is always conversation around changing the course of fire, target dimensions, or putting certain rifles into different classes. I like the fact that I have to adapt myself to fit the current discipline. I would surely not want to make it any easier. I feel like that would decrease some of the satisfaction that I get from competing well.
Q: What are your key gear items and shooting accessories?
Brian: A good shooting coat has been very important for me. I currently use a Creedmoor Hardback Cordura Leather Coat. I also think that a good rifle sling is very important. For the last couple of years I have been using a Eric Hollis National Match leather sling and love it. I own a ShotMarker e-Target system and I think it’s one of the best training tools that I own. It just makes it so easy to shoot, capture information, and then be able to recall that information later and use it to improve.
The Mental Game — How to Become a Better Marksman
Q. What is your pre-match routine (mental/physical match prep)?
Brian: I try not to do anything different on match day that I would do any other day. I am a coffee drinker and drink just as much on match day as I do on any work day. This game is very mental, and I find that treating match day just like any other day helps me to control stress and anxiety.
Q. If you could do it all over from the beginning, how would you change your training/practicing processes?
Brian: I have learned that practice makes me better, but just sending rounds down range is not that beneficial to me. Some of the biggest improvements I have made have come from practice sessions where I did not fire very many rounds. Working through the shot process, being honest with myself, and evaluating what needs to happen to get the desired outcome.
Q. Most guys will never achieve what you’ve done in Marksmanship, i.e. win multiple multi-gun titles. What are the other positive things people can get from the sport, beyond trophies and glory?
Brian: This is an easy one — this sport is full of the most genuine, thoughtful, and helpful people out there. I have friendships with people that I only see a couple times per year… yet when we see each other it’s like we had just gotten together last week. This does not just apply to fellow competitors, but also to the folks who run matches, to those who supply gear, even to spouses of competitors who’ve fed me more times than I can remember.
Brian “Carbine” Williams, King of Wood Guns
— Commentary by Dennis Santiago
When it comes to CMP Games competition, Brian Williams presently dominates the multi-gun field. I first met Brian at the so-called Michigan Embassy at Camp Perry, a makeshift compound of tables, pop ups and lawn chairs where competitors gather at the end of the shooting day to exchange stories. It’s a “who’s who” gathering of High Power personalities exchanging tall tales. In this prestigious crowd, Brian Williams is “King of Wood Guns”, his mastery of the GSMM (Garand, Springfield, Modern Military) Four-Gun Aggregate renown to all. Yet he is as humble a champion you can ever hope to spend time with.
I discovered that Brian and I share a mutual love of the U.S. .30 Caliber M1 Carbine, a rifle many other shooters don’t give a second thought. But we believe in the potential of the little gun. We know that when driven right, the joy of collecting gold achievement pins with it. I’ve enjoyed trading notes with Brian about how to make it shoot better to turn in scores in the high 360s to mid-370s out of a possible 400. In this regard, I assure you Brian is again the guy who will shoot the 400 possible on any given day. He truly deserves the moniker “Carbine” Williams.
BONUS: Rimfire Sporter — Brian’s Fifth Gun
Along with his centerfire rifles, Brian Williams likes to shoot in CMP Rimfire Sporter matches. In fact, he won the Rimfire Sporter Match “O” Class (Iron Sights) at the 2021 CMP Eastern Games. Shown below is his Czech-made .22 LR CZ 452 Ultra Lux bolt-action rifle.
Q: How do you like Rimfire Sporter? Do you have to adjust your technique for rimfire vs. centerfire?
Brian: Most of the fundamentals will transfer from centerfire guns to the rim fire guns, the biggest difference is in the course of fire for the match. The Rimfire course of fire includes a slow-fire seated stage, and a rapid-fire standing stage, both of these stages are unique to the Rimfire Sporter game. I enjoy this discipline, but due to the scheduling of the Rimfire Sporter match at Nationals I have not yet shot this event at Camp Perry. I did do well in this event at both the Eastern CMP Games and New England CMP Games.

This Armalite AR-50A1 .50 BMG rifle was modified by G.A. Precision.
If you’re a fan of big boomers, and love shooting steel, then definitely watch this Wide Open Magazine video. This covers a .50 BMG build by our friends at G.A. Precision (GAP). The rifle started as an Armalite AR-50A1 ($4750.00 MSRP). Then GAP fluted the barrel and swapped the factory muzzle brake with a more compact brake from American Precision Arms*. Then, as modified, the entire rig was given a rugged Cerakote finish.
The video has nice background music (pretty loud), great aerial drone footage, and of course some serious firepower. Using Hornady .50 BMG ammo, GA Precision’s George Gardner and his Wide Open friends shoot the big Fifty from the bench as well as prone. Enjoy!
About the .50 BMG Cartridge
The .50 Browning Machine Gun (.50 BMG, aka 12.7×99mm NATO or 50 Browning) is a cartridge developed for the Browning .50 caliber machine gun in the late 1910s, entering official service in 1921. Under STANAG 4383, it is a standard cartridge for NATO forces as well as many non-NATO countries.
John Browning had the idea for this round during World War I in response to a need for an anti-aircraft weapon, based on a scaled-up .30-06 Springfield design, used in a machine gun based on a scaled-up M1919/M1917 design that Browning had initially developed around 1900. According to the American Rifleman: “The Browning .50 originated in the Great War. American interest in an armor-piercing cartridge was influenced by the marginal French 11 mm design, prompting U.S. Army Ordnance officers to consult Browning. They wanted a heavy projectile at 2700 FPS, but the ammunition did not exist. Browning pondered the situation and, according to his son John, replied, ‘Well, the cartridge sounds pretty good to start. You make up some cartridges and we’ll do some shooting’.”
* In the video, George mistakenly says “American Patriot Arms”, but the brake is made by Georgia-based American Precision Arms.
Brian, a gunsmith at GA Precision, built this rimfire rig with GAP colleague Anthony Soukup.
On his Facebook page, Tactical competitor Bryan Sikes posted a photo of a rimfire rig we really liked. Brian works at GA Precision. He and fellow GAP gunsmith Anthony Soukup built this rifle. With a modified Rem 40X action, Manners stock, Bartlein barrel, and Mack Brothers suppressor, this rig has top-quality components stem to stern. And Bryan tells us this rifle performs as good as it looks: “This is the baddest little .22 LR trainer ever. I’m stoked about it. With the barrel length and can, it’s the exact length of my regular comp rigs.” With length, balance, and ergonomics near identical to Bryan’s centerfire competition rifles, this 40X is a superb training tool.
Many readers wanted to know about the bottom metal and the detachable box magazine. Bryan Sike reveals: “The magazine setup is designed specifically to replicate my actual competition rifles. The bottom metal is for use with AI magazines and uses a standard M5 type inlet just like any centerfire completion rifle. In this case with the .22LR, Mike Bush designed a high reliability rimfire magazine using the same outside dimensions as an AI magazine. This rifle was built no different from any other. The action was modified and trued, barreled, fully bedded, etc. using ALL components common to centerfire match rifles.” The Rem 40X action was modified by Modacam Custom Rifles to work as a repeater with box mags.
Bryan adds that a new rimfire action is in the works: “My preference is modified Remington 40X actions and the soon-to-be available, V-22 action from Mike Bush. Both of which are TRUE repeaters and don’t feed from a Savage magazine. This rifle feels nothing like a .22 LR and that was the whole point.”
Why You Need a .22 LR Tactical Cross-Trainer
Many guys who shoot long-range tactical matches practice with .22 LR rifles of similar configuration. Rimfire ammo is way more affordable than centerfire, you do not need a big range facility, and shooting rimfire saves wear and tear on your centerfire rifle. Further, for learning how to read the wind, there really is no better training tool than a .22 LR, even as close as 50 yards.
Our Friend “DesertFrog”, who shoots tactical matches in Southern California, explains: “I used to shoot an average of 200 rounds of .308 Match ammo a month for training (50 per weekend). These days I shoot maybe an average of 50 rounds of .308 Win per month and probably around 600 rounds of .22 LR. Using mainly the .22 LR for practice did NOT hurt my standings in actual competitions. I shot my .308 just as well in matches, but saved the cost of hundreds of rounds of .308. If I didn’t reload and was still buying boxes of Federal Gold Medal Match .308 Win [at $1.90/round], this would be a savings of [$350 per month on the centerfire ammo.]” Money saved is money earned.

A few months ago, Forster Products released a limited run of a new prototype Primer Pocket Swaging Tool for the Co-Ax press. This is a metal shaft that attaches to the base of the press. After receiving very positive feedback from initial testers, Forster has determined to offer the product again, priced at $30.00 for a set of two (2) swage tools (for both small and large primer pockets). CLICK HERE to order.
Intial Testing Feedback on Forster’s Swaging Tool:
Several reloaders told us the tool required less force than expected and preferred using it over other swaging methods. Setup was straightforward, and overall performance removing military crimps from .223/5.56 brass was consistent and effective.
One customer ran over 270 cases through the tool across multiple headstamps and reported solid results removing 3- and 4-point crimps. Others noted that once properly adjusted, it did a clean job swaging primer pockets and allowed primers to seat properly afterward.
A few important observations also came through:
• Brass varies — even cases with the same headstamp can behave differently.
• Heavily crimped brass may require more care during operation.
• As with any swaging operation, excessive force can damage rims if the operator overpowers the case.
In other words — the tool works well, but like most case prep operations, proper setup and feel matter. Overall, Forster reports that user reports have been very positive given the good performance on real benches. Because of that response, Forster has made another limited quantity available.
If you process crimped military brass on your Co-Ax press and want to streamline primer pocket prep without adding another expensive, standalone tool to your bench, the new swaging tool for the Co-Ax is now available for $30.00. This include both small and large swaging units. CLICK HERE to order.
Here’s something of interest for benchrest competitors, particularly those who shoot at 100/200/300 yards. In those disciplines, high magnification is very important, and fixed-power options are popular. And in a game where the goal is to shoot in the ones and zeros, it is absolutely vital to have a scope that never experiences even the slightest shot-to-shot change (drift), and that allows very precise adjustments for windage and elevation. If you have a scope that moves internally, even the slightest amount, from one shot to the next, that can ruin a group.
Sightron offers a competition scope that should be a serious option for benchrest shooters. The Sightron SIII Competition 36x45mm ED riflescopes offer quality glass, precise adjustments, and reticles that hold steady — with no drift from shot to shot. This is a side-parallax scope with 1/10 MOA click values. Two Reticles are offered: Fine Crosshair (FCH), and FCH with 0.125 MOA Target Dot. This scope is in stock now at Creedmoor Sports for $1259.99, or direct from Sightron for the same $1259.99 price.
Sightron SIII Competition 36x45mm ED Specifications:
Sightron ExacTrack Windage and Elevation
When you’re trying to shoot one-hole groups, you need a scope that holds its values, and can also give precise, 100% repeatable adjustments when you need to dial a windage or elevation change. This SII ED’s ExacTrack windage and elevation adjustment system maintains proper alignment of the adjustments to the erector tube. That, Sightron says, ensures “precision and accuracy even when the most dramatic adjustments are applied.” NOTE: The adjustment values for both windage and elevation are 1/10th MOA. That is unusual. We usually see 1/8th MOA clicks in this type of scope. Here the click values are one-tenth Minute of Angle. (NOT 1/10 MIL). Sightron notes: “Precise target knobs with 1/10th MOA click value provide hair-splitting accuracy.”
ED (Extra Low-Dispersion) Glass in New 36x45mm Optic
The SIII Competition 36×45 ED features precision ED glass for crisp, razor-sharp views with minimal chromatic aberration — Sightron promises “crystal-clear target definition” with no color hazing. The SIII SS 36x45mm ED boasts Zact-7 Revcoat multi-coated precision ground lenses. Sightron claims “the highest quality light transmission in the industry”. A side parallax adjustment knob allows the riflescope to focus from 10 yards to infinity.
This article was originally written by noted rimfire gunsmith Bill Myers. Sadly, Bill passed away in May 2010, but his legacy lives on. He pioneered many advancements in rimfire gunsmithing and Myers-built guns still win matches in benchrest competition.
Crafting competitive rimfire benchrest rifles is considered an art as much as a science. The smith must understand subtle, yet critical aspects of vibration control, barrel tuning, and rifle balance. In the United States, only a handful of gunsmiths consistently turn out rimfire BR rifles that consistently run at the front of the pack at major matches. Bill Myers was one of those master craftsmen. In this article Bill discussed the process of building a winning rimfire BR rig. He reveals some interesting secrets, including his procedures for testing bedding performance and his barrel indexing system. Bill’s methods obviously work, as the Suhl-actioned rifle featured here won a truckload of trophies in its very first match.
Building a Match-Winning Rimfire Benchrest Rig
by Bill Myers
In my opinion, a winning rimfire benchrest rifle is probably twice as difficult to build as a competitive centerfire rifle. The relatively slow .22 LR bullets stay in the barrel much longer than centerfire bullets. This means that vibration control is critical. Likewise bedding is critical. Bore finish and lapping are very important. The amount of bore taper or “choke” can have a huge effect on accuracy. Ignition is also very important and above all, rimfire BR rifles need a very stable stock that tracks perfectly. A rimfire that shoots great is a marriage of all components and the shooter’s need to be aware of everything possible.

The rifle featured in this article was built from scratch with attention to all the details that go into accuracy. The goal was to build a gun that could win from the get-go. This would be a “Spec Gun”, meaning a rifle that was personally tested and tuned by me for optimum performance before it went out to the customer.
The Suhl trigger is as good as it gets so no change was needed. It easily adjusts down to about 2 ounces.
Baer Stock in Bubinga Wood
There are many choices when you start to build a complete rifle. It has to shoot well and it has to catch ones eye, or it’s just another rifle on the line. I prefer wood stocks on rimfires for two reasons: they are very stable if the right wood is used and they have a certain traditional appeal to many shooters. I chose Bubinga wood for this particular gun because it is very stable and heavy, it has a very dense grain and a very pronounced figure with a natural red color. The Bubinga is a very forgiving wood to work with.
Gerry and Bruce Baer in Pennsylvania do all my stock blanks. I do all my own inletting and bedding. The blank weighed 4.5 pounds when it came off of Bruce Baer’s duplicator. This Bubinga wood is so hard that it did not need pillars, but I put them in anyway. I bed all my stocks with Loctite Steel Bed liquid and add filler to desired thickness. The final bedding is done with an aircraft tooling epoxy that does not deteriorate over time. The stock has an ebony butt plate and 6 coats of automotive clear, polished to a high finish.
Suhl 150-1 Action Accurized and BN-Nickel Plated
I used a new, unfired Suhl 150-1 action. As explained in the sidebar below, the Suhl 150 actions were originally crafted in East Germany for position rifles. They have a very fast lock-time and come with an outstanding trigger. However, they need some work when adapted to a modern BR gun. The action needed to be accurized and threaded. I have a special tool that I use to accurize actions. It uses two sets of spiders for dialing-in the bolt raceway. After the bolt raceway is running true, one can thread and true up all bearing surfaces so that everything is in perfect alignment with the action raceway bore.
BN-Nitride Plating on Action
I decided to plate the action and all bolt parts with Boron Nitride nickel plating. I bough the BN Electroless Nickel Kit from Caswell Plating and did the job myself. I started by bead-blasting the action so that it would end up with a “satin” finish. The plating material is then applied in a tank. The Boron Nitride goes directly into the plating solution, but you need to use a pump to keep the solution agitated so the BN distributes evenly.
Once the action is completely ready (the metal must be perfectly prepped, with no contaminants), the process goes easily and can be completed in about half an hour. The end result is a very slick, low-friction finish, that is .0002″ (two ten-thousandths) thick and hard as glass. The Boron Nitride makes everything very smooth. After the plating job, the action was noticeably slicker than before.
The cone breech (photo below) permits the barrel to be INDEXED (rotated around bore axis) to any position on the clockface. You then test various rotation settings to find the best accuracy. The system does work. Some barrels shoot best in a particular rotational setting. E.g. with index mark at 3 O’clock vs. 12 O’clock.
Fitting and Chambering the Barrel
As for a barrel, I had two good choices: one Shilen 1:16″-twist, 4-groove ratchet and one Benchmark 1:16″-twist, 3-groove. Both barrels were very accurate and at the end, I decided to leave the Shilen on the rifle because I wanted to put the Benchmark on another Suhl I’ve set aside for myself. I chambered the barrel for Eley flat nose EPS. We’ve found the gun also shoots the new Lapua X-ACT ammo very well.
The barrel finished at 25″ long and features a tuner by the Harrell brothers of Salem, Virginia. I use a flat 90° crown–it’s the most accurate and its gives a good seal against the tuner. I also use a 45°, 12-flute cutter that leaves no burr when cutting the crown. This chamfer protects the crown when cleaning the barrel. There is no sharp edge for the brush or jag to hit on the return stroke. The barrel was headspaced at .043″ and I use a tapered reamer ground by Dave Kiff of Pacific Tool & Gauge in Oregon. The chamber leade area is lightly polished to remove reamer burrs. The breech end of the barrel is machined with a 1/2″ ball end mill to produce what I call a “Myers cone breech.” Technically, it has a sloping radius as you can see, rather than a straight-sided cone. Finishing the breech in this fashion facilitates indexing the barrel, as the barrel can be rotated to any position (on the clockface), without requiring new extractor cuts.
Barrel Indexing — Finding the “Sweet Spot”
When indexing a barrel, one rotates it to different clockface positions relative to the action. Imagine marking a barrel at TDC or 12 o’clock, and then rotating it so the mark is at 3 O’clock, 6 )’clock, 9 O’clock and so on. At each position one shoots groups to determine at which index setting best accuracy is achieved.*
I know that barrel indexing is controversial. I don’t want to get into a lengthy debate other than to say that I believe that careful and thorough testing can reveal a “preferred” index position for a good barrel. With the barrel set in that particular position relative to the action I believe the barrel can yield optimal performance.
I perform the indexing tests indoors at 50 yards. I use a rail-gun with floating action. The barrel is held in place with a clamping fixture similar to an Anschutz 2000-series action. Basically, two vertically-stacked metal blocks clamp around the barrel. I can index the barrel this way simply by unclamping the barrel blocks, rotating the barrel and then re-clamping the system. I have a special system so the action can stay in the same position, even as the barrel is rotated.
It takes time and effort to get solid indexing results. Normally I shoot at least 400 rounds of ammo in 3-4 indexing sessions. Shooting a handful of groups is not enough. You may think you’ve identified the best index position, but you need to shoot many more rounds to verify that. Also, in a very good barrel, the effects of indexing may be subtle, so it will take many groups to confirm the optimal position. In my experience, really good “hummer” barrels do not benefit as much from indexing as an “average” barrel.
Accuracy Testing with Both Barrels
I tested the rifle indoors at 50 yards at the Piney Hill Benchrest Club range. There was no finish on the stock, but it shot well in my one-piece rest with the Benchmark 16-twist, 3-groove barrel and no added weight on the tuner. I shot 30 rounds of Eley Match EPS Black Box (1064 fps) and had 25 Xs and five 10s on the IR 50/50 style target. Not too shabby for a new barrel with no special break-in.
When the Shilen barrel arrived, I installed it on the rifle. By this time the stock had been clear-coated and finished, and the action had been polished and plated. I shot the Shilen barrel outside since it was too hot in the building. The first target was a 250-19X with a new lot of Eley Match EPS Black Box (1054 fps). The gun shot well. My friend Tony Blosser asked to shoot the gun, and he drilled a 250-20X in a steady wind using the same Eley ammo. See target at right.
Advanced Procedures — Vibration Control and Tuner Position
Barrel Tuning Using 2-Way Electronic Indicators
Before competing with this rifle, I put it in a firing fixture I use to tune the barrel. I employ a pair of very expensive Swiss 2-way electronic min/max hold indicators. These measure both up movement and down movement of the barrel as the gun is fired. I can measure the actual vertical travel of the barrel at any position from the front of the receiver to the tuner. I can also tell how long the barrel vibrates, time-wise. Using this fixture I found that the Shilen barrel was very consistent in readings and seemed to work well with no additional weight on the tuner. No barrel ever stops vibrating completely — but this was close, showing less than .002″ of total movement.
Bedding and Vibration Control
I have found that measuring the actual movement of the barrel during firing tells me a lot about the quality of the bedding. I have learned that if I see very big movements (e.g. .010″ up and .005″ down), then there may be a problem with the bedding. I saw this kind of big swing on a rifle with bedding that had not cured properly.
Another pattern I watch for is uneven vertical movement. For example, if the barrel vibrates .008″ up but only .002″ down, that tells me the bedding has issues. As noted above, I look for minimal vibration travel (after the tuner is fitted and optimized), and I also want that travel to be relatively equal both up and down. Good rimfire gunsmiths agree that proper bedding has an important influence on vibration control and tuning. By measuring actual barrel movement during firing, we can, to an extent, quantify how well the bedding is working. At a minimum, we can see if there’s a serious bedding problem.
Trial by Fire — Shooting the Gun in Competition
After semi-gluing in the action, the rifle was shooting great. So, I decided to take it to the Maryland State Unlimited Championship to see if it was truly competitive — whether it could “run with the big dogs”. As it turns out, the Bubinga Suhl was more than just competitive. The rifle won three of the six cards and won the meters championship. In the photo below you can see all the trophies the gun won in its very first match. One of the other competitors in Maryland, dazzled (and perhaps a bit daunted) by the Bubinga Suhl’s stellar performance, told me: “Sell that gun Bill. Whatever you do, just get that darn rifle out of here.” Confident that this was a rifle capable of winning major matches, I packed up the rifle and shipped it to Dan Killough in Texas. Killough has shot some impressive scores with the gun.
Suhl Target Rifles — East Germany’s Legacy
Suhl 150 rifles were manufactured in former East Germany (GDR) by the Haenel firearms factory in the town of Suhl. This region has a long history in arms production. In 1751, Sauer & Sohn founded the first German arms factory in Suhl. Following WWII, Suhl 150s were produced for Communist Bloc marksmen, including East German Olympic shooters. Prior to German unification, the East German national shooting arena was located at Suhl and hosted many top-level competitions including the 1986 ISSF World Championships.
Superb Rifles with Amazing Triggers
As a product of East Germany, the “mission” of the Suhl 150 was to rival the accuracy of the Anschütz, Walther and other premium match rifles built in the West. East German shooting teams wanted to finish on top of the podium, so they needed a rifle with superb inherent accuracy. The Suhl 150s have an outstanding trigger that can be adjusted down to about two ounces. The Suhl 150 action, like the Anschütz 54, boasts an extremely fast lock-time — an important factor in a position rifle. And Suhl barrels were legendary for accuracy.
Suhl 150 Benchrest Conversions
Many of the first used Suhl 150s that made it to America were converted to Benchrest rifles because the action/trigger/barrel combination was unbeatable for the price. Some of the barrels on these “surplus” Suhls were phenomenal — as good as any custom barrels available today. It was not unknown for a Suhl 150 barreled action, transplanted into a benchrest-style stock, to win BR matches with the original barrel. Today, however, most of the Suhl benchrest conversions end up with modern, American-made barrels. While some older Suhl barrels can “shoot with the best of ‘em”, new barrel designs optimized for use with tuners have an edge, at least in benchrest circles. That’s why builders such as Bill Myers swapped out the Suhl barrel with something like a Benchmark reverse-taper two-groove.
Today Suhl 150 rifles are very hard to find in North America. In 2006, a used Suhl 150, even without sights, might fetch $1200.00 or more. Then, in 2007 through early 2008, hundreds of Suhl match rifles were imported. This drove prices down, and those “in the know” snapped up complete Suhl 150s at prices ranging from $450 to $850 (see 2007 advert at right), depending on condition.
Many of these rifles were left “as built” and used successfully in prone competition. Others were converted into benchrest and silhouette rifles, “parted out” for the actions and triggers. If you were able to grab one of those imports at a good price–consider yourself lucky.
* Bill Myers actually created his own clamping rimfire action to facilitate barrel indexing. CLICK HERE to view Myers Rimfire Action. To index the barrel, Myers simply loosened three clamping-bolts and rotated the barrel in the action. Because there is no thread to pull the barrel in or out, the headspace stays the same no matter how much the barrel is rotated. With a threaded action, you might have to use shims to test different rotational positions, or otherwise re-set the shoulder with each change.
Here’s a new option for hunters and tactical competitors who want to range targets and call windage/elevation corrections using their spotting scopes. Vortex is now offering Reticle Eyepieces for its Viper HD spotting scopes. Available in both MRAD and MOA versions, these fixed-power 33.5X eyepieces feature ranging reticles with handy hash marks. This allows target ranging, plus competitors can “make accurate shot calls… with subtension lines for holdover and windage corrections.”
Vortex states: “The all-new eyepiece makes measuring target range and calling shot corrections easy, with a diopter ring that allows shooters to get the reticle dialed to their eyes, and level with the horizon line, no matter how their scope is setup.”
Powering the new eyepiece is a fixed, 33.5X magnification ocular lens. This provided plenty of power most hunting and competition scenarios. The eyepiece glass is protected with ArmorTek and XR lens coatings. These easily-installed ranging eyepieces, both MRAD and MOA, are designed for a wide field of view so user won’t miss a single vapor trail or bullet splash.
Ranging MRAD — Hashmarked ranging reticle using MRAD-based subtension lines for ranging, holdover, and windage corrections. Secondary ranging references facilitate rapid range estimating.
Ranging MOA — Hashmarked ranging reticle using MOA-based subtension lines for ranging, holdover, and windage corrections. Secondary ranging references facilitate rapid range estimating.
These eyepieces have fixed, 33.5-power magnification. “Street Price” is about $200.00.
The gun, crafted by Eric Wallance of Nawaka Firearms, features an XP-100 action, Jewell trigger, and 15″-long, Brux 1:8″-twist barrel with aluminum muzzle brake. Interestingly, this gun does not have a traditional recoil lug. Instead, gunsmith Wallace milled out a lug from the bottom of the XP-100 action to save weight. On top of the action, the rig carries a Sightron Inc S-III 6-24X56mm scope in Kelbly rings on a custom +20 MOA rail.
All shooters, even rimfire enthusiasts, should always wear ear protection when at the range. A typical rifle gunshot is very loud — in the region of 140 to 170 decibels (the pain threshold is 130-140 db). Without ear protection, you can permanently damage your hearing during a single shooting session. We all know older shooters who are partially deaf, or who suffer from 
Bullet Selection — With the .30-06 for my Garands and Springfields I stick mostly with 168gr bullets plus some 155-grainers. These bullet weights have just worked for me in the past. 
Power Charge and Dispensing — I have always had good success with Hodgdon H4895 powder. My load has always been right around 47.0 grains, with both the 168gr and 155gr bullets. I also use the Auto-Trickler to drop all of my powder charges. This is a fantastic piece of equipment that not only gives super-consistent powder charges quickly, but it also makes one less thing that you have to worry about while on the firing line. With the Auto-Trickler, there is never a question about the powder charge in your ammo. As for primers, I have been shooting CCI 200 Large Rifle primers for many years and have never had an issue. 
Brian: I have learned that practice makes me better, but just sending rounds down range is not that beneficial to me. Some of the biggest improvements I have made have come from practice sessions where I did not fire very many rounds. Working through the shot process, being honest with myself, and evaluating what needs to happen to get the desired outcome.
