Sunday GunDay: Radical Skeleton-Stock Rifles from Texas


A few seasons back, our Editor and his friend Joe Friedrich flew to Texas to visit Gene Beggs and test rifles in Gene’s 100-yard indoor tunnel. That was a once-in-a-lifetime opportunity to shoot centerfire rifles in such a test facility. Here’s our report…

The South Texas Tunnel

Gene Beggs operates his own 100-yard indoor tunnel and rifle testing facility just outside of Odessa, Texas. Surrounded by tall fencing, this place really looks like a “Area 51″ secret military facility.

In his South Texas tunnel, Gene provides instruction and “tunnel time” for serious benchresters looking to improve their skills and optimize the accuracy of their rifles. Along with teaching the fine points of short-range benchrest, Gene employed his tunnel to develop a pair of radical rifles, one chambered in 220 Beggs, a slightly modified 220 Russian, and a second chambered in 6mm Beggs, a necked-up version of the 220 Russian that retains the original body taper and shoulder angle.


Radical Skeleton Stocks with Aluminum Sled mounted to Barrel
Both rifles shared a skeleton design which uses the Stiller Cobra or Viper action as a central load-bearing member. Remarkably, there is no conventional fore-arm at all. Gene has bolted, directly to the barrel, a 3″-wide bag-riding aluminum sled. The sled was not designed as a mid-barrel tuner, but it might have some beneficial effects in that regard. However, the tuning functions are handled by two concentric rings threaded to the muzzle. Gene believes that with minor rotations of his front tuning rings, he can dial the gun into tune and the tune can be easily adjusted as conditions warrant.

Do Mr. Beggs’ guns shoot? Absolutely. We had the chance to visit Gene in Odessa. We shot both the 220 Beggs-chambered rifle, and its 6mm Beggs-chambered cousin. Both rifles are nearly identical, though the Heavy Varmint-weight 220 has a longer, 27″ barrel compared to 22″ for the Light Varmint 6mm.

In the tunnel, the 220 HV, with a no-turn-neck 220 Beggs chamber, produced three-shot groups in the low ones and zeros right out of the gate, even before the tuner was optimized. With a barrel with over 1000 rounds through it, after firing 40 rounds without cleaning, Gene produced a tiny 5-shot group in the low ones. The first shot was slightly high (a common occurrence in the tunnel according to Beggs). The last 4 shots, rounds 42-45 since the barrel had been cleaned, went into 0.084″. This rig, though radical in the extreme, certainly appears fully competitive with more conventional BR rigs, and it tracked superbly, with no hopping or rocking on the bags.

220 Beggs — Simple, Accurate, Efficient

We were also very impressed with the 220 Beggs cartridge. It’s basically a plain 220 Russian with a sharper radius at the neck-shoulder junction. Gene has commissioned a 220 Beggs reamer with matching seating and full-length sizing dies. The little cartridge achieves 3600+ fps with a 52gr bullet, pushed by Benchmark powder.

Less Recoil Than 6PPC — From what we could tell during our short visit, the 220 Beggs is easy to load for, and performs exceptionally well with either turned (.250″) or no-turn necks. The recoil was noticeably less than a 6mm PPC, making the gun a joy to shoot. This round, we felt, could also be an outstanding varmint cartridge. The velocity is there, and we don’t think any other 22-caliber varmint cartridge is going to beat it for inherent accuracy.

As for the 6mm version, Gene told us: “The 6mm version of the cartridge performs best with Hodgdon’s H4198 Extreme, but the 220 has proven it will shoot well with just about anything you put in it including N133, H322, Benchmark, 8208, Norma 200 etc. It is the most trouble-free, user friendly cartridge I have ever worked with and will compete heads-up with anything. It’s also very easy on the shoulder.”

Gene Beggs sells components (reamers, dies etc.) for the 220 and 6mm Beggs, and also, under special circumstances, offers training/testing sessions in his West Texas Tunnel on an appointment basis.

Practice with SCATT Training System — Trace Muzzle Movement

SCATT MX-02 rifle training optics trace tracking system

Our friend Dennis Santiago was doing some dry firing practice recently, using a SCATT sensing device. This electro-optical unit shows a trace of barrel/muzzle movement on a computer screen, allowing a shooter to improve his hold and aiming. With practice, you get steadier, and learn to break the shot more perfectly. Top position shooters worldwide use this system. Dennis tells us: “This is my dry fire practice set up. I’m working on my approaches to the target today. You need the SCATT’s traces to see the feedback of what’s going on.” Here is one trace from Santiago’s morning training session:

SCATT MX-02 rifle training optics trace tracking system

Dennis trains indoors at his house: “The set-up is in a room with the target about 15 feet away mounted on a scope stand at eye height and aligned. This morning, it’s focus and trigger control. My offhand form is gonna get there bit by bit. There are many details to turn into instincts.”

SCATT MX-02 Training System

The SCATT MX-02 is an electronic shooter training system that is capable of operating outdoors with live, centerfire ammunition, at distances from 25 yards to 600 yards. Tony Chow tested this product for AccurateShooter.com. As fitted to his AR-15 Service Rifle, Tony concludes this is a very useful tool that can help High Power competitors refine their technique and shoot higher scores. FULL REVIEW HERE.

SCATT MX-02 training digital camera sensor target

How the SCATT MX-02 Works
The SCATT sensor mounted on the end of the barrel has a digital camera that recognizes the black bullseye in the target, even in broad daylight outdoors. Using the bullseye as a reference, the SCATT software tracks the movement of the muzzle relative to the center of the target. The unit can plot these movements as a continuous trace, which appears on a monitor as a squiggly, colored line. By sensing the exact moment of shot release, the SCATT can also interpolate relative shot placement (for a single shot or series of shots) — but this is not the same as an electronic target which actually records the exact shot impact location on the target.

Pro shooter Kirsten Joy Weiss demonstrates the SCATT MX-02 electronic training system:

The system traces and records valuable information such as hold pattern, shot hold duration, follow-through, recoil pattern, and much more. The latest SCATT MX-02 systems can be used both indoors and outdoors up to 300 meters (and possibly more). READ FULL SCATT MX-02 TEST HERE.

.22 LR Handguns Suitable for Self-Defense — Video Showcase

22LR .22 LR long rifle handgun pistol twenty-two revolver video review

We think everyone should have a .22 LR pistol or revolver (and probably both). Whether for plinking, target shooting, or “back-up” self-defense, a good .22 can perform a multitude of roles. Today, with the help of YouTube reviewers, we look at a variety of .22 LR pistols, focusing on compact .22s that can serve for self-protection, as well as plinking fun.

Can a .22 LR be an effective defense weapon? One retired officer posted: “As a police officer I saw more people killed by .22 or small caliber than with a 9mm or larger. I would not want to be shot by one. The benefits I see are minimal recoil, the ability to conceal, easier follow-up shots, [and] cheap ammo meaning more range time and training.”

Top .22 LR Handguns for Self-Defense — Video Reviews
22 Plinkster has shot hundreds of thousands of .22 LR rounds, through dozens of .22 LR handguns and rifles. Here are his “Pick Six” of compact .22 LR handguns that can work for self-defense. All of these pistols are compact and relatively light-weight. 22 Plinkster adds: “I didn’t list a few handguns in this video for a few reasons. Yes, there are other great options out there, but other guns can’t be concealed as easy as the guns that are in this video. Pistols like the Walther PPQ or the Taurus TX22 will make my top 5 list, just not this one.”

This lengthy 53-minute video reviews over a dozen semi-auto .22 LR Pistols. This is one of the most comprehensive comparison on the internet. The reviewers compare the new Glock 44 with many other options on the market, including rimfire pistols from Beretta, Ruger, SIG Sauer, Smith & Wesson, Taurus, Walther and more. Target-style pistols are reviewed as well as smaller carry-style .22 LR pistols.

This video is another round-up with ten different .22 LR handguns. There are semi-autos from Beretta, Ruger, Smith & Wesson, and Walther. This video also features the tiny North American Arms .22 revolver, the classic S&W Model 63 revolver, and the Ruger LCR-22 compact carry revolver. The reviewer praised the Ruger SR22, which his wife carries. He says the “SR22 has so far been flawless — not one misfire. It is incredibly accurate and reliable. At only 0.9″ thick it is very conceable”.

The Effectiveness of .22 LR Round is Under-Rated
The folks from Lucky Gunner state: “Pocket pistols and revolvers chambered for the humble .22 LR are easily dismissed as carry guns suitable only for novices and the elderly. While there are some definite drawbacks to relying on a small gun that fires small bullets for self-defense, it also may have significant advantages that even skilled and experienced shooters can benefit from.” This video has been viewed over 1.5 million times.

.22 LR Mini-Mag Tested in Ballistic Gel — You May Be Surprised
Here are two videos that reveal how a .22 LR Mini-Mag performs in test gel. In both videos, testers shoot the CCI .22 Mini-Mag into Ballistic Gel. The results are pretty impressive. This is still a .22 LR cartridge, but the potent Mini-Mag packs some punch, particularly at close ranges.

Yes a larger centerfire round carries more energy. But the Mini-Mag can do the job. One knowledgeable YouTube commenter, a retired LEO with 41 years of service, stated: “NEVER underestimate the power of a .22 CCI Mini-Mag. During my career, when working with a Medical Examiner, I [witnessed] bodies riddled with a .22. I don’t have to paint GORY details.”

Winter Range Cowboy Action Event in Phoenix This Week

SASS Winter Range Ben Avery Phoenix Cowboy action mounted shooting

Earlier this month the Ben Avery Range in Phoenix hosted America’s top long-range shooters at the Berger SW Nationals. This week, Feb. 24 – March 1, 2020, over 1000 cowboys and cowgirls take over Ben Avery during Winter Range, the SASS National Championship for Cowboy Action Shooting. Winter Range is the second largest Cowboy Action event of the year, after End of Trail, the Single Action Shooting Society World Championship held each year in Edgewood, New Mexico.

SASS Winter Range Ben Avery Phoenix Cowboy action mounted shooting

If you want to check out the action at Winter Range, admission is free. The Ben Avery Shooting Facility is located on Carefree Highway, west of Interstate 17. For more information, visit WinterRange.com.

This video, produced by the Arizona Fish and Game Commission, covers the full Winter Range experience, including the main shooting competitions, the side matches, the Western costumes, the socializing, and more. Worth watching if you like action shooting or are a fan of the Wild West.

Hundreds of cowboy action shooters, ages 12-80, will compete in multiple classifications based on age, and type/caliber of firearms. In addition, this year the Cowboy Mounted Shooting Association and the SASS Mounted Shooters will hold a two-day mounted shooting event February 29 through March 1, in nearby Queen Creek, Arizona.

winter range ben avery phoenix

Cowboy Action Shooting requires that contestants compete with firearms typical of those used in the taming of the Old West: single-action revolvers, lever-action rifles, and period shotguns. Participants each have a registered cowboy shooting alias (such as “Deadeye Dave”), used in SASS events. Competitors, organized in “Posses”, shoot a series of multi-gun stages. In addition to the primary competitions, Winter Range 2020 will feature displays of period militaria, exhibitions of western skills and crafts, a fast-draw contest, and nearly 100 vendors selling vintage-style clothing and “sundries”.

Sunday GunDay: The Klemm Clan — Father and Son F-TR Aces

Ian Klemm Ken Klemm F-TR Rifle Father Son USA Team F-Class champion
Ian Klemm won back-to-back 2017/2018 USA F-TR National Championships. His next big challenge will be the 2021 World Championships, where his father Ken Klemm will be one of his teammates on Team USA.

Over the last 30 years, a family saga has been playing out in rural Wisconsin: a father fosters within his son the joy of competitive target shooting. It started in a basement shooting range of a small-town elementary school, shooting single-shot rimfire target rifles while cementing the fundamentals of sight alignment, breathing, trigger control, and safety. With a background of competitive smallbore shooting in school and the U.S. Navy, Ken Klemm coached his son, Ian, in a father/son indoor winter shooting league. Ian was determined to shoot as well or better than his Dad and would pursue that goal for the next 30 years. Even after his engineering career took him to the Washington DC area for defense-related work, Ian continued to compete with his Dad by mailing “postal match” targets back and forth for many years.

Ian Klemm Ken Klemm F-TR Rifle Father Son USA Team F-Class champion
Ian and Ken Klemm have shot successfully together as members of Team X-Men.

Ken even came to visit Ian out east, with rifle in tow, where they entered the Virginia State 1000-yard Benchrest Championship on a whim with their entry-level (factory) F-Class rifles. Ken’s record target measured 0.003″ smaller than his son’s but Ian was getting closer to matching his Dad. Ian eventually moved back to Wisconsin after taking a design job with Vortex Optics, only a few miles from his hometown, and now he and his Dad could compete in earnest, both against each other and as teammates on the X-Men F-Class club team.

Ian’s trigger time increased significantly with his new vocation and he was lucky enough to design a new competition scope, the Vortex Golden Eagle, for both to use. Armed with two nearly identical new rifles and their new optics, Ian and Ken began traveling cross-country together to compete alongside their X-Men teammates, winning multiple National F-Class Championships together.

Matched F-TR Rifles with Kelbly Actions, McMillan X-It Stocks, Bartlein Barrels
Both Ken’s and Ian’s match rifles are built using the same winning hardware — Kelbly actions, McMillan X-It stocks, and Bartlein barrels. Also, Ian and Ken both run similar loads: Lapua .308 Win Palma brass, Vihtavuori N150 Powder, and Berger 200-20X bullets. In addition to the components listed below, they use some special equipment: bipod lowering kits from FClassProducts.com, large rear bigfoot bags from Seb Lambang (SebRests.com), and “Dri-Gun” rain protection from BarrelCool.com.

Ian Klemm Ken Klemm F-TR Rifle Father Son USA Team F-Class champion

Father and Son Share their Winning Strategies
Having each other to share tips and techniques and confirm winning strategies with has certainly helped Ken and Ian compete successfully together over the last few years. Common between them are the strategies of bracketing wind conditions with sighters as well as using the Golden Eagle’s aperture stop ring (ASR) to more effectively observe mirage and ultimately quantify wind value. They both try to shoot in a building wind condition as it more slowly increases in velocity while challenging each other to stop during a string at the first sign of a potential “let off” or sudden decrease in wind velocity.

Ian Klemm Ken Klemm F-TR Rifle Father Son USA Team F-Class champion
Ian and Ken competed successfully as teammates on Team X-Men. They shared winning strategies, such as bracketing wind conditions with sighters.

The only significant difference in how each of them wins is in their gun handling. Ken maintains the most consistent form and smallest groups by assuming very light shoulder pressure and virtually no grip contact with his rifle. In contrast, Ian is most competitive with a medium-firm pressure on both the grip and forearm of the McMillan X-It stock as well as medium shoulder pressure. Both techniques have proven themselves during competition when employed consistently.

Ian Klemm Ken Klemm F-TR Rifle Father Son USA Team F-Class champion

Unlike many F-TR shooters, two-time F-TR National Champion Ian Klemm grips the fore-end of this rifle when he shoots. Ian explains:

“I use a piece of Kydex thermoplastic (commonly used in holsters) that I formed around the forearm (see photo above). I index off it when gripping the stock with my weak hand to ensure that I’m always contacting [the stock] in the same spot. I grip this while shooting, for every shot. It was quickly assigned to my subconscious since I was so used to gripping the fore-end after years of hunting. It felt unnatural to me to not be doing anything with my off-hand. By letting my subconscious do what comes naturally, I am able to achieve a higher level of consistency that if my conscious mind was ‘trying’ to accomplish something with that other hand. The relatively stiff McMillan X-IT stock feels like it benefits from more contact in terms of vibration during the shot as well.”

Father and Son Will Shoot for Team USA in 2021 World Championships
The United States F-Class Rifle team has just completed a 2-year tryout period consisting of multiple tests and scored drills designed to determine which developmental candidates would be named to the final travel team ultimately representing our country against the rest of the world during the next quadrennial World F-Class Championship in South Africa, April 2021. Ken and Ian were just recently informed that they had both been named as shooters on that Final Team USA Selection. This is the first time, to our knowledge, that a father and son have shared that honor as teammates on a USA Rifle Team.

Ian Klemm Ken Klemm F-TR Rifle Father Son USA Team F-Class champion
Here are Ken and Ian on the 2019 FCNC Team. Both father and son have been selected to shoot with the 2021 USA National F-TR Team which will compete at the World F-Class Championships South Africa.

The level of competition from the leading countries around the world is expected to be even stronger this cycle than in previous ones, with correspondingly slimmer margins of victory. Along with the rest of their US teammates and coaches, they will practice and prepare as a dedicated team over the next year to build a sense of confidence and trust in one another. Ken and Ian are thankful for the opportunity to share this experience of a lifetime together and for the 30-year long practice session leading up to it.

.224 Valkyrie Barrel Cut-Down Velocity Test — 4 Ammo Types

224 .224 Valkyrie barrel cut-down test velocity 90gr Sierra MatchKing Fusion SP TMK

224 .224 Valkyrie barrel cut-down test velocity 90gr Sierra MatchKing Fusion SP TMKVelocity vs. barrel length — How much speed will I sacrifice with a shorter barrel? Hunters and competition shooters often ask that. Today we DO have solid answers to that question for many cartridge types thanks to Rifleshooter.com.

Rifleshooter.com has conducted a series of barrel cut-down tests for many popular chamberings: .223 Rem, 6mm Creedmoor, .243 Win, 6.5 Creedmoor, .308 Win, .300 Win Mag, .338 Lapua Magnum and more. And recently Rifleshooter.com added the new .224 Valkyrie cartridge to the list, cutting a 28″ Shilen barrel down to 16.5″ in one-inch increments. Rifleshooter.com measured the .224 Valkyrie’s velocities at each barrel length with four different types of factory ammo.

For its .224 Valkyrie test, RifleShooter.com sourced a Shilen Match Barrel and fitted it to a Rem 700 short action employing a one-piece PT&G bolt with the required .440″ (SPC-sized) bolt-face. The barreled action rides in a MDT LSS-XL Gen 2 Chassis.

READ .224 Valkyrie Barrel Cut-Down Test on Rifleshooter.com »

Bill, Rifleshooter.com’s Editor, explained his test procedure:

“I gathered four different types of factory Federal 224 Valkyrie ammunition, the 90gr Sierra MatchKing (SMK), 90gr Fusion soft point (SP) (referred to a Fusion MSR), 75gr Total Metal Jacket (TMJ) and 60gr Nosler Ballistic Tip Varmint (NBT). After a brief barrel break in and zero, I fired 5 rounds of each cartridge at each barrel length (except the 75 TMJ, I fired 4 rounds at each barrel length due to limited resources). I recorded the average muzzle velocity and standard deviation for each ammunition and barrel length combination and cut the barrel back 1 inch and repeated the process. I recorded barrel lengths from 28″ to 16.5″ (I try to save these barrels as finished 16″ tubes so they don’t go to waste).”

224 .224 Valkyrie barrel cut-down test velocity 90gr Sierra MatchKing Fusion SP TMK

The Heavy Bullet 90gr Ammo Lost about 21 FPS per Inch
How did the test turn out? You’ll find all the results summarized in helpful tables with inch-by-inch velocity and SD numbers. For the two, 90gr ammo samples, results were similar. The 90gr SMK ammo started at 2782 fps (28″), finishing at 2541 fps (16.5″). That’s a loss of 241 fps, or 20.96 fps average per inch of length. The ammo loaded with 90gr Fusion SPs started at 2797 fps (28″) and ended at 2561 fps (16.5″), a drop of 236 fps. That’s 20.5 fps loss per inch. NOTE: Ambient temperature during the test was 45° F. You could expect the overall velocities to be a bit higher during hotter summer months.

See 90gr SMK Velocity/Length Test Chart | See 90gr Fusion SP Velocity/Length Test Chart

.224 Valkyrie Velocity Cut-Down Test

With a the smaller bullets, the effect was even more dramatic. As you’d expect they started out faster. The ammo with 60gr Nosler Ballistic Tips (NBT), a good choice for varminters, started at 3395 fps (28″), and declined to 3065 fps (16.5), a total velocity drop of 330 fps. Average velocity loss was 28.7 fps per inch of barrel length. Rifleshooter.com also tested Federal 75gr TMJ ammo.

About the .224 Valkyrie Cartridge

224 .224 Valkyrie barrel cut-down test velocity 90gr Sierra MatchKing Fusion SP TMK

The new .224 Valkyrie was introduced late last year as a Hot Rod cartridge that will work in AR15s. Designed to rival the .22 Nosler while still running well in ARs, the new .224 Valkyrie offers excellent long-range performance when loaded with modern, high-BC bullets. We expect some bolt-action PRS shooters might adopt the .224 Valkyrie. Why? Reduced recoil. With the 90gr SMK, the .224 Valkyrie offers ballistics similar to the 6.5 Creedmoor but with significantly less felt recoil. Check out this chart from Federal showing comparative recoil levels:

.224 Valkyrie Federal Rifleshooter.com cut-down barrel

.224 Valkyrie vs. .22-250 Remington
The Social Regressive explains: “There are two key reasons why the .224 Valkyrie is unique and desirable. First, it is specifically designed to fit the limitations of the AR-15 platform. It does so even when loaded with gigantic bullets, like the 90-grain SMK that Federal announced. The .22-250 Rem is too long and too fat to work in the AR-15 platform; it needs an AR-10 bolt and magazine.”

Image from Social Regressive .224 Valkyrie Youtube Video.

The new .224 Valkyrie is basically a 6.8 SPC case necked down to .22-caliber. You can use your existing AR15 lower, but you will need a dedicated .224-Valkyrie upper, or at the minimum a new barrel, modified bolt with proper bolt face, and 6.8-compliant mags.

Gunsmithing Gone Bad — How NOT to Headspace a Barrel

Locktite Red barrel shoulder headspace Thomas Speedy Gonzales
This barrel’s shoulder was 0.025″ off the action because Red Locktite had been used on the threads.

Gunsmith Thomas ‘Speedy’ Gonzales offered this interesting report about how NOT to headspace a barrel. Hopefully you never discover something like this…

“A good friend and customer sent this rig in for repair after FedEx damaged the rifle during inbound transport from another smith. After repairing the stock and rebedding it, I decided to re-polish the barrel to make the repair perfect. Well this just added insult to injury as the barrel did not want to come off. After a few choice words, the barrel finally broke free only to reveal something very disturbing. It seems the barrel had been ‘headspaced’ by using RED Loctite to hold it in place.” [Editor: That’s definitely NOT how barrels should be fitted.]

Speedy was not happy: “I hope the smith that did this sees the photos and realized what jeopardy he put my customer in or anyone who shot the rifle for that matter. When cleaned up, the shoulder on the barrel was over 0.0250″ (25 thousandths) away from the face of the receiver.” [Editor: That’s a lot in this business]. Check out the images below to see how much the barrel rotated further inward when cleaned up. The barrel spun in nearly another eighth-turn or more. Not good.
