Even seen an integrally suppressed rifle? Ruger offers this technology with its new Silent-SR ISB, a multi-baffle integrally suppressed barrel (ISB) for Ruger 10/22 takedown models. This system reduces sound levels to an average of 113.2 dB with standard velocity ammunition. That’s very impressive — consider that an unsuppressed .22 LR firearm can produce noise levels as high as 140 dB with standard velocity ammunition. That’s well above the threshold where irreversible hearing damage begins. (Source: NC Silencers).
Even if you are not interested in a suppressed rimfire rifle (or live in a state where suppressors are forbidden) we think you’ll be interested in Ruger’s technology. The Silent-SR employs a long, multi-element “baffle stack” that can be easily removed for cleaning.

Here’s what Ruger says about its new ISB (Integrally Suppressed Barrel) for the 10/22 Take-down:
The Silent-SR ISB quickly and easily assembles to any Ruger 10/22 Takedown or 22 Charger Takedown, and features an induction-hardened breech with cold hammer-forged barrel that provide easy takedown and accurate return-to-zero.
Reducing sound pressure levels of .22 LR to an average of 113.2 dB with standard velocity ammunition, a 10/22 Takedown rifle equipped with the Silent-SR ISB is as quiet as a bolt-action rifle with a thread-on silencer. The relatively long barrel of the Silent-SR ISB (compared to other integral suppressors) means the bullet generates energy near that of a 16″ gun for consistent, accurate and effective performance on target. The pushed-cone baffle geometry has been stretched to utilize the volume under the barrel maximizing suppression of the gunshot without disturbing the travel of the bullet.
Disassembly for cleaning is as simple as separating the barrel from your firearm and loosening the Silent-SR ISB’s single assembly screw using the included 5/32″ hex key tool. Once loose, pull the screw to remove all six 17-4 stainless steel baffles, spacer and front cap free of the sleeve for cleaning. The sealed baffles keep the fouling away from the serialized sleeve, yet easily come apart even after thousands of rounds. Finished with Cerakote, the Silent-SR ISB is engineered and built for a lifetime of hard use without clogged ports, seized components or loss of suppression that often plague other integrally suppressed rimfire barrels.

Steyr Arms has introduced a new straight-pull rimfire rifle that should work well for rimfire practical/tactical games, cross-training, and varmint hunting. Available in three chamberings, .22 LR, .22 WMR, and .17 HMR, the new Steyr Scout RFR emulates the look of a Scout Rifle, but in a rimfire platform. This rifle, which first appeared in 2016 in Europe, made its American debut at the NRA Annual Meetings in Atlanta this week.
Frankly, we don’t need or want the extended forward-mounted rail, because we would use a conventional higher-magnification optic, rather than a long-eye-relief scout scope. But we are excited about the straight-pull action, 10-round magazine, and nicely-designed stock that should be good for tactical comps. For mounting conventional scopes, an integrated 3/8-inch dovetail base runs the full length of the receiver’s topside, and the RPR comes with Weaver bases mounted on the top of the receiver. MSRP is $599.00.
Detail showing ISSC Biathlon-style SPA straight-pull action with trigger-guard safety.
Based on the proven, biathlon-inspired SPA action built by Austrian gun-maker ISSC, the Steyr Scout RFR was designed as an economical, minimal-recoil trainer. Available in .22 LR, .22 WMR, and .17 HMR, the Scout RFR has a smooth, straight-pull action allowing for fast cycling with the provided 10-round magazine. Check out the video below to see how the action works. Trigger pull weight is 3 lbs, 4 oz., about right for tactical games. We might want a slightly lighter trigger for varmint work with the .17 HMR version. In fact, we think this might make a great “squirrel gun” in .17 HMR.
The Scout RFR’s Eloxal-coated aluminum receiver secures a 20″ heavy-contour barrel. Both the .17 HMR and .22 LR barrels are 1/2-20 UNF threaded for attachments, while the .22 WMR barrel is unthreaded. The Scout RFR measures 35.6 inches long, and it weighs 7.3 pounds without optics. An optional knife stows in the stock, and standard Steyr SBS/Scout buttplate spacers can used to adjust length-of-pull. Included accessories: Owner’s manual, two Weaver adapters, and one 10-round magazine.

Here’s a great Do-It-Yourself (DIY) project from Martin Tardif. Build your own height-adjustable ammo caddy for under ten bucks. This is a great project for F-Open competitors as well as anyone who shoots with a pedestal front rest, either on the ground or from a bench. The ammo caddy attaches, via a flexible arm, to your front rest. The flexy arm allows you to position your ammunition close to your rifle’s feeding port. That makes it easy to grab cartridges and load them into the chamber without shifting your shooting position. Nice job Martin!
Martin Explains How to Build the Ammo Caddy
Here are some pics of my DIY P.L.A.B. (Port Level Ammo Block). I cannibalized the goose neck from a Craftsman bendy-style utility light and bought a 3.5″x 1″ Acetal disk on eBay. I then drilled out the disk to accept twenty .284 Winchester rounds and screwed the disk to the bendy arm. The arm, by itself, wasn’t sturdy enough to support my fully loaded ammo block, so I inserted a 1/8″-diameter steel rod cut to length into the arm before I screwed it to the disk. On this Bald Eagle rest, I wasn’t using the windage adjustment cable. That allowed me to secure the bottom end of the arm to the unused 5/16″ x 18 bolt hole for the cable. [Editor’s Note: For other pedestal rest types/brands you may need to drill a hole for the base of the flexy arm.]
Kudos to Martin Tardif for his clever use of inexpensive materials. The total cost of the whole project, according to Martin, was just $8.00!

Estimating Actual Cost per Round by Caliber
This article comes from the USAMU, which provide shooting and reloading tips on its Facebook Page. This week’s USAMU TECH TIP outlines a ballpark-estimate method of calculating the actual cost per round of different calibers. Some applications, and some shooters, by virtue of their high level of competition, require the very best ballistic performance available — “Darn the cost, full speed ahead!
If you are in serious contention to win a major competition, then losing even a single point to inferior ballistic performance could cost you a national title or record. However, this “horsepower” does come at a cost! Some calibers are barrel-burners, and some offer much longer barrel life. Look at this comparison chart:
Estimated Cost Per Round by Cartridge Type
Below are some estimated total expense per round (practice and competition) based on component costs, type used, expected barrel life and a standard, chambered barrel cost of $520.00 across calibers.
5.56x45mm: $0.46/round (barrel life 6,000 rounds)*
6mmBR: $0.81/round (barrel life 2800 rounds)
6XC: $0.97/round (barrel life 2200 rounds)
.308 Win: $0.80/round (barrel life 4500 rounds)
6.5-284: $1.24/round (barrel life 1100 rounds)
*Note the high round count estimate for 5.56x45mm. This is a bit deceptive, as it assumes a period of “lesser accuracy” use. The USAMU says: “Much of the difference you see here between 5.56 and .308 is due to using the 5.56 barrel for 100-200 yard training with less-expensive, 55gr Varmint bullets after its long-range utility is spent”.
Moreover, while some applications require specialized, high-cost components, others do not. And, if the shooter is still relatively new to the sport and hasn’t refined his skill to within the top few percentile of marksmen, a more economical caliber choice can help stretch a limited budget. Translation: More skill per dollar!
In this post, the prices for all items mentioned here were taken from a major component supplier’s current advertisements, and all brass was of top quality, except in the case of 5.56mm. There, 200 top-quality, imported cases were reserved for 600-yard shooting, and the other brass used was once-fired Lake City surplus.
Cartridge cases were assumed to be loaded 10 times each. [Your mileage may vary…] Bullet prices assumed the use of less-expensive, but good-quality match bullets for the bulk of shooting as appropriate.
The cost of top-tier, highly-expensive match bullets was also calculated for a realistic percentage of the shots fired, based on ones’ application. Barrel life by caliber was taken from likely estimates based on experience and good barrel maintenance.
Brass Costs Based on 10 Loads Per Case
Often, handloaders may calculate ammunition cost per round by adding the individual costs of primers, powder charges and projectiles. Many don’t consider the cost of brass, as it is reloaded several times. Here, we’ll consider the cost of enough top-quality brass to wear out a barrel in our given caliber, at 10 loads per case, except as noted above.
Don’t Forget Amortized Barrel Costs
Few shooters factor in the full, true cost of barrel life. Depending on caliber, that can dramatically increase the cost per round. For example, consider a long-range rifle in 6.5/284 caliber. This cartridge performs amazingly well, but at a cost. Ballpark estimated barrel life [in a top-quality barrel] is 1100 rounds. Some wear out faster, some last longer, but this gives a rough idea of what to expect.
Accurate barrels are a joy to use, but they are an expendable resource!
A top-quality barrel plus installation was estimated at about $520.00. At 1100 rounds, barrel life adds $0.47 per round to our total cost. Thus, what had started out as an [components-only estimate, with brass cost] of $0.76/round now totals $1.24 per shot!
Cost Considerations When Choosing a Catridge Type
Some shooters might ask themselves if they could meet their present needs with a more economical caliber. If so, that equates to more practice and matches per available dollar, and more potential skill increase on the available budget.
Each shooter knows his skill level, practice needs, and shooting discipline’s requirements. Some might shoot NRA Service Rifle or Match Rifle using a 5.56mm with a long barrel life. Others might be Match Rifle shooters faced with choosing between, say, a 6mm BR vs. 6XC. A realistic assessment of ones needs, performance-wise, may help guide the shooter toward a caliber that’s most optimized to their needs at the moment.
Admittedly, the factors affecting cost for any individuals circumstances can vary significantly. However, hopefully this will provide one useful method of evaluating one’s training and competition choices, based on their skill, goals and needs.

Do you carry a firearm for self-protection, or perhaps keep a handgun in a vehicle during trips? Then you should consider signing up for a new insurance/training program offered by the NRA. Launched this week, the NRA’s Carry Guard program offers up to $1,000,000 in insurance/legal protection. This is combined with a comprehensive training program.
The Carry Guard program offers a 24/7 hotline for members. You get immediate response to secure bail bonds, legal retainers, and counseling. Importantly you can choose your own attorney from a nationwide attorney referral network. Members get up to $1,000,000 in insurance-backed protection for legal fees and will receive emergency support services in case of a self-defense incident. Spouses of NRA Carry Guard members are automatically covered, as are family members who live with a Carry Guard member and defend themselves in the home.
Three levels of protection are offered, with affordable monthly payments. When you consider that the cost of defending a civil lawsuit could easily exceed $150,000 just in legal fees, it’s smart to have some kind of legal insurance plan.
Carry Guard Training
Carry Guard members can access a variety of video tutorials. In addition, CarryGuard offers three-day training programs that combine classroom sessions with range training. The focus is on the real-life scenarios you might face. “We apply those [gun-handling] fundamentals to real-life situations, self-defense tactics and techniques, low-light shooting, force-on-force Air Soft scenarios and more. Students are evaluated on a course of fire where only a passing score earns eligibility to move to the next level.”
If you have questions about the Carry Guard Program, consult the Carry Guard FAQ page, call 1-866-NRA-5050, or use the NRA’s Contact Form.

Do your hands/wrists get tired when prepping scores of cartridge cases? There’s an alternative to the big, costly case prep centers that occupy lots of space on your reloading bench. Little Crow Gunworks has developed a $29.95 hand tool that makes chamfering by hand much easier. You’ve got to watch this Precision Prep Tool in action — click on the VIDEO below to see Gavin Gear of UltimateReloader.com demonstrate how it works.
See How Tool Head Spins With Arm Movement — Very Clever!
With this tool, a natural motion of the forearm translates into rotary motion of the tool head (watch the video!). The tool-head holds four (4) tools: inside and outside neck chamfer tools, plus large and small primer pocket reamers. A hex adapter lets you use the primer pocket reamers with a power drill to remove the crimps on military brass.
Gavin Gear was impressed with this innovative device: “I’ll admit, I didn’t know how this tool worked until I tried it out, and it’s pretty amazing how something so simple can make such a big impact on a chore like brass prep. I’ve tried a lot of brass prep tools, and this is one smooth setup. I think the Precision Prep Tool is a good option for case prep chores, especially if you want to trim on the go, or sitting in your recliner watching TV.”
This is the first manually-operated case prep tool that puts four tools at your fingertips. Other single-head inline tools require the user to twist their wrist or rotate the tool in their hand. The PPT consists of a knurled solid aluminum handle with a bearing-mounted aluminum tool head. The tool head has four 8-32 tapped holes which accept case prep tools manufactured by most reloading companies. To use the tool, simply rotate your forearm in a clockwise motion to chamfer, deburr, or clean the primer pocket. Priced at $29.95, the tool comes in five (5) colors: Red, Blue, Green, Silver, and Black.

Mother of All LR Primer Tests
If you shoot a .308 Win, or any cartridge that uses a Large Rifle (LR) primer, you should read an important article by Laurie Holland in Target Shooter Magazine. Holland, a talented shooter from the UK, tested no less than sixteen (16) different large primer types using a custom F-TR target rifle shot from the bench. Laurie loaded .308 Win ammo* with 16 LR primer varieties and then tested for average velocity, ES/SD, and group size. This may be the most comprehensive and thorough LR primer test ever done. Here are the primer types tested:
1. CBC Magtech 9½
2. CCI 200 LR
3. CCI BR2 Match
4. CCI 250 Magnum
5. Federal 210
6. Federal 210M Match
7. Federal 215M Magnum Match
8. Fiocchi Large Rifle
9. Kynoch Large Rifle
10. Murom KVB-7 (PMC LR)
11. Norma Superflash LR
12. PMC LR Magnum
13. Remington 9½ LR
14. Remington 9½ M Magnum
15. Sellier & Bellot LR
16. Winchester WLR
Test Rig: Osprey Rifles-built F-TR rifle with Savage PTA action, 32″ Bartlein 1:12″-twist ‘Heavy Palma’ barrel, and Dolphin Gun Company modular stock with an F-Open/Benchrest fore-end.
Some of Laurie’s results may surprise you. For example, would you guess that Sellier & Bellot primers had the lowest ES, by a significant margin? And get this, among ALL the primers tested, Rem 9½M Magnum primers produced the lowest velocity, while Rem 9½ LR (non-magnum) primers yielded the highest velocity. (The total velocity spread for all primers was 35 fps). That’s counter-intuitive and it’s odd that Rems were at opposite ends of the speed spectrum among ALL primers tested.
“The rationale for doing side-by-side tests is to see what effect primer choice has on ballistics, i.e. average velocities and MV consistency. There are a great many views on the subject, a few based on tests (including primer flame photography) but most apparently hearsay.” — Laurie Holland
Every serious hand-loader should definitely read the full test results to understand Laurie’s methodology and get all the details. This is an important test, with significant findings. But if you can’t spare the time right now, here are some highlights below:
Primer with Lowest Velocity: Remington 9½ M Magnum (2780 fps)
Primer with Highest Velocity: Remington 9½ LR (2815 fps)
Primer with Lowest ES/SD: Sellier & Bellot LR (12/3.1 fps)
Primer with Highest ES/SD: Remington 9½ M Magnum (47/14.0 fps)
Primer with Smallest Group Size: Remington 9½ LR (0.43″ average, three 5-shot groups)
Primer with Biggest Group Size: CBC Magtech 9½ (0.7″ average, three 5-shot groups)
Editor’s Comment: Laurie shot three, 5-shot groups at 100 yards with each primer type. The average group size for the top six primers varied by only 0.10″ (0.43″ to 0.53″), so one can’t conclude that one type is much better than another. Total group size variance (from best to worst) was 0.27″.
“The biggest surprise to me … came from an elderly (at least 10 years) lot of Czech Sellier & Bellot standard caps with an ES of 12 and SD of 3.1 fps, way below those of the nearest competitor. By contrast to the Fiocchis, they were an almost slack fit in the cases and this may have contributed to their consistent performance.” — Laurie Holland
NOTE: Values in chart are based on 15-Shot strings. The ES/SD numbers will therefore be higher than is typical with five-shot strings.
All ES/SD Values from 15-Shot Strings
Testing 16 primer types was a huge task — we commend Laurie for his hard work and thoroughness. This extensive test is an important contribution to the “knowledge base” of precision shooting. Laurie’s findings will doubtless influence many hand-loaders who hope to produce more consistent ammunition, or achieve better accuracy. Credit should also be given to Target Shooter Magazine for publishing the results. Well done gentlemen…
*Reloading method for Test Ammo: “Test batches consisted of 16 or 17 rounds for each primer, charges thrown by an RCBS ChargeMaster and checked on lab-quality electronic scales, adjusted if necessary to within ± 0.04gn, so any charge weight variation would be under 0.1 grain which equates here to 5 fps.”

All 10s and Xs for record — that’s a very impressive 200-10X score card for young Lynzie Graham.
Here’s a “feel-good” story about a talented young shooter. We like to acknowledge the accomplishments of the “rising stars” in our sport. Lynzie Graham, a member of the U.S. F-Class Under-25 Team recently shot a perfect 200-10X at 600 yards, not dropping a point. That’s particularly impressive when you consider Lynzie shot her 600-yard “clean” using a factory rifle — a Savage Arms .308 Win F-TR rig.
Congratulations Lynzie Graham on your first 600-yard “clean” at the Texas State Qualifier in February 2017. Lynzie was shooting the Sierra 180gr MatchKing® #2220 with her Savage F-TR .308 Win. This August, Lynzie and other U.S. F-Class U-25 Team members will be competing at the F-Class World Championships (FCWC) hosted at the Connaught Ranges near Ottawa, Canada.
