A while back, Cal Zant at PrecisionRifleBlog.com did a big muzzle brake comparison test. Along with measuring recoil reduction, Cal’s team recorded sound levels in PRB’s exhaustive muzzle brake field test. In the PRB archives you’ll find comprehensive muzzle brake sound test results, with hard data on 20 different muzzle brakes.
Sound can be a tricky subject, but Cal Zant, the editor of PrecisionRifleBlog.com, presents everything an informed shooter should know about muzzle brake noise in a straightforward and practical way. Most sound tests are measured from the side of the muzzle, in accordance with mil-spec standards, and Cal did that. But he also measured the sound level of each brake from behind the rifle, closer to the shooter’s position. This provides a more accurate indicator of the actual sound levels firearms operators will encounter while shooting.
Muzzle brakes ARE really loud — that’s something most active shooters have observed. But this study finally gives us some hard data and makes objective comparisons. The difference between brakes was quite significant. Some brakes were ear-splitting — more than twice as loud as other brakes tested.
As a bonus, Cal also provides data on how the new Ultra series suppressors from Thunder Beast Arms Corp (TBAC) compare in terms of sound level behind the rifle.
Useful reloading gear does not have to be costly. Here are ten handy (and very inexpensive) items that belong on your loading bench or in your range kit.
• Magnifying Glass – We use a flat, 2″x2″ pocket 4x-8x magnifier. This folds up on itself. Very handy, we use it to inspect bullets and brass. Use this to check your flash holes for burrs, and check the meplats of your bullets before loading.
• Clear 35mm Film Cannister – Use this to transfer the thrown powder charge to the little measuring cup that sits on your scale. That way you don’t get any kernel splash. Also if the charge weight is obviously off, it’s easy to dump back in the measure. A film canister works pretty well as a trickler too.
• Compressed Air in a Can -- Get these at office supply stores. Use the can (with tube attached) to blow crud out of cases after cleaning the neck with a brush, and blast loose debris out of primer pockets.
• Pin Vise – A simple pin vise with a #53 bit is perfect for deburring Lapua PPC and BR flash holes without reaming the flash-holes any larger. The Lapua PPC/BR flash-hole diameter is 1.5 mm, or 0.059″. Amazon.com sells a handy $8.99 pin vise kit with 10 bits, including the ideal 1.5mm bit. Other vendors offer a #53 pin vise bit that measures .0595″ or .060″ (depending or source). You can find pin vises and bits at hobby stores — here’s an example below with ten bits including 1.5mm. Pin vise sets can be found from $7 to $15.
• Bounce Dryer Sheets – The common dryer sheets eliminate “static cling” on your plastic reloading parts such as powder measure cylinders, powder funnels, and reloading press plastic bins. Thanks to Doc76251 for this tip.
• Ballistol Aerosol – Try using this versatile lubricant/solvent for full-length sizing. Spray some on a patch and you can wipe the carbon off your case necks. Then, continue to apply a very small amount of Ballistol on the case bodies — just thin sheen is all you need. Ballistol is super slippery, and easy to remove. For general full-length sizing (on small cases) it works great and doesn’t leave a gooey, waxy, or chalky residue. For heavier case-forming jobs, we recommend Imperial Die Wax.
• Shotgun Mop – Stick this in the chamber when using Wipe-Out foaming bore cleaner. This will seal off the chamber so the foam doesn’t flow into your action. For long chambers screw on one section of cleaning rod to aid extraction.
• Colored Sharpie Marking Pens – Mark your bullets ahead of the bearing surface, and the color transfers to the target. This way you can shoot multiple loads at the same point of aim and discern which load shoots the tightest. (Recommended for 300 yards and beyond). With colored bullet tips you can test multiple loads “round robin” to equalize wind effects. When testing seating depths for example, you can mark the longer-seated set of bullets red and the shorter-seated set green and shoot them during the same sequence. Just look at the colored marks on the target to see which grouped better.
• Thin Latex Gloves – You should keep a box of inexpensive, disposable latex gloves (the kind doctors use) in your loading room. These will prevent contamination of primers or powder kernels that you handle directly. Also, use the gloves when handling fine blued tools or firearms to prevent transfering body oils and salts that promote rust.
• Plastic Washers for Neck Mic – If you use a Sinclair Neck-wall Micrometer Gauge with integral stand, you can use thin plastic washers to adjust the height of the case on the mandrel. This makes it much easier to measure the same point on the case neck every time. Thanks to MikeCR for this tip (and photo).
Can a $1300 Ruger compete with a $7000 high-end sniper rifle from the UK? That was the question posed a few years back by Frank Galli, Head Honcho of Sniper’s Hide. Galli, aka “Lowlight”, conducted an interesting comparison test, running the $1300 Ruger Precision Rifle (RPR) vs. a $7000 Accuracy International AX in a 450-yard “mad minute” drill. The goal was to see how many shots could be put on a 12″ steel target in one minute. Both rifles were chambered for the 6.5 Creedmoor and were fed with Hornady 140gr Amax ammo. The much cheaper Ruger did surprisingly well, though the AI AX did come out on top. Galli got 19 rounds on target in one minute with the AI AX compared to 14 rounds with the Ruger.
Watch the “Mad Minute” face-off in this video:
Galli notes: “The target is 450 yards away, and, as noted in the video, we have winds gusting anywhere from 10 to 18 mph out on the Front Range of Colorado today. So my job is to not only hit the target as fast as possible, but to also manage the conditions.”
In Summary
Frank Galli says the Ruger offers a lot of bang for the buck:
“For those looking to get into competitive tactical shooting, like a PRS Event, there is absolutely no excuse. This rifle will allow you to be competitive, the only thing that would hold a person back is themselves. The more this rifle is shot, the more impressive it is. Would I trade my Accuracy International for one? Well, odd question, but no. However for those on a budget I would recommend the Ruger in a heartbeat.”
Upgrades for Ruger Precision Rifle — RPR Enhancements
After conducting this test, Galli added some upgrades to his first-generation RPR, with bolt-on parts. Improvements included new barrel, stock, grip, and handguards. The first video below runs through the selection and installation of parts, while the second video shows the upgraded RPR being tested in the field. These two videos have been watched over half-a-million times combined. Note, the current-generation RPR has different handguards than shown in the photos.

If you’re a fan of “Heavy Artillery” here’s an impressive rifle that Forum member “Straightpipes” crafted himself nearly a decade ago. Even today, it remains a state-of-the-art engineering Tour De Force, complete with a custom-built, joy-stick REAR rest. We’re mightily impressed by the innovative design and superb metal-work displayed by this “home-built special”. ‘Straightpipes’ certainly proved that American “know-how” and creativity is still alive….
Coaxial (joy-stick) rests allow both vertical and horizontal movement with a single control. If you want to make a diagonal shift in point of aim, you can do this with one, smooth, continuous movement. Until now, this advantage has been limited to front rests. Well there’s some new technology in the benchrest world. Forum member ‘Straightpipes’ has created a coaxial rear joystick rest. He built this simple, compact rear rest in his home workshop for use with his 40-lb Heavy Gun. In combination with a vertically adjustable front rest, this innovative rear joystick rest allows aiming to be controlled from the rear, with your left hand in a comfortable position. Yes this kind of adjustable rear rest is legal in NBRSA HG and LG classes, and in IBS Heavy Gun class.
Straightpipes Rear Coaxial Rest — Design and Features
The rear rest is crafted from aluminum with a stainless steel forward-pointing joystick. Total weight, including the long, stabilizing base foot, is about 10 pounds. Though the rear rest doesn’t seem to have a large movement range, the system offers plenty of “on-target” travel. At 100 yards, the rest offers 10 MOA left, 10 MOA right, 5 MOA up, and 5 MOA down adjustment. That’s plenty of range for most targets, once you center the Point of Aim vertically using the captain’s wheel on the front rest, which Straightpipes also crafted himself. Click Square Photos Below to see Large Images.
Inside the rear cradle sits a Protektor rear sandbag, with Cordura fabric filled with ordinary sand. This fits the 3″-wide bottom of Straightpipes’ 40-lb heavy gun. There are some sophisticated components you can’t see in the photos. The rear rest can pivot (right or left slightly) to stay aligned with the front rest (as adjusted to level the cant of the rifle). Straightpipes says: “With the pivot, whatever I do to the front, the rear follows.” The basket (cradle) also employs a 20-lb bias spring system to handle the weight of the Heavy Gun. This prevents the co-axial system from binding, so it is fluid and easy to operate. Even with 20 pounds of gun weight on the rear, the joystick can be easily manipulated with a light touch of thumb and fore-finger.
Video Shows Rear Coaxial Rest in Action
Watch the video below to see how the joystick controls the rear rest. Total joystick movement is about a 2.5″ sweep. This gives 20 MOA total windage adjustment at 100 yards, and about 10 MOA vertical.
About the Straightpipes Front Rest
The coaxial rear rest is designed to work with the massive front rest as a system, though they are NOT connected, so as to comply with IBS Heavy Gun rules. The 30-lb front rest supports exactly half the weight of the rifle and is used to set gross elevation. Windage and fine elevation is controlled in the rear. Straightpipes also designed and built his beefy front rest himself. As with his rear coaxial unit, the front rest pieces were all shaped by hand on a belt sander after being milled out. Straitpipes even “finish-sculpted some pieces with hand files the old craftsmen way.” The main center support column was milled with extremely fine threads. This allows the captain’s wheel to turn with little effort and no locking mechanism is required. Straightpipes does not need to fuss with locking knobs when he sets gross elevation. To help keep the unit from binding, there are stainless guide shafts on the left and right. These shafts slide in oil-impregnated bronze bushings.
40-lb Barrel Block Heavy Gun with Savage Action
Straightpipes built this beautiful set of rests to work with his 40-lb Heavy Gun. Chambered in 7mm WSM, the gun features a Savage Target Action, and a Brux 32″, 1.300″ straight-diameter barrel fitted with a custom barrel nut. The barrel is clamped forward of the action in a 9″-long barrel block. This allows the Savage action to free-float. The block, also built by Straightpipes, looks fairly standard, but it has some clever design features. Between the barrel and the block there is sleeve that is slightly compressed when the block’s bolts are tensioned. This sleeve, made of a proprietary material, eliminates metal to metal contact between barrel and block. Straightpipes believes this enhances accuracy and provides some damping. Other shooters with barrel-block guns have used epoxy between block and barrel, but that makes disassembly difficult. The sleeve system on Straightpipes’ gun allows the barreled action to be easily removed from the stock. In addition, the compressed sleeve system is very stable — Straightpipes doesn’t have to fiddle with the bolt torques on his block.
‘Black Beauty’ Stock Made from Resin-Soaked Laminated Wood, with Rust-Oleum Finish
Straightpipes built the beefy stock himself. It is made from “red oak” wood soaked in resin and then laminated together with JB Weld. The rear section features a polished aluminum buttplate and twin metal “runners” on the underside, where the stock rides the Protektor Cordura bag. Straightpipes says the stock is very stable: “it absolutely does not flex or warp with changes in temp or humidity”. We asked Straightpipes about the stock finish. To our surprise, “Pipes” revealed he used inexpensive Rust-Oleum fine texture outdoor furniture paint. “Pipes” told us: “I’ve been using this stuff for years. It’s abrasion proof and tough as nails — the bags won’t wear it off. It’s solvent-proof, won’t get soft or bubble up. It cleans up with a damp cloth, just rub it down and it looks like new.”
As designed and crafted by Straightpipes, this Heavy Gun rest system is impressive. The rear rest is brilliantly simple, and beautifully finished. But the important question is: “how does it shoot?”. Straightpipes reports that the whole system exceeds his expectations: “The rear rest actuation is smooth and positive. It works smoothly in conjunction with the front rest. Everything is working together — there’s nothing that’s fighting another element of the system. The gun tracks straight. When it returns to battery, the thing is pretty much waiting for you shot after shot.” The rear rest’s small footprint allows the “driver” to sit comfortably behind the rig. Straightpipes reports: “Shooters can ‘address the rifle’ just like a Light Gun — you’re not straining to wrap your arm around something overly massive. Anybody can shoot this, it’s a very easy gun to shoot.”
Is it accurate? In a word, “Yes”. Straightpipes doesn’t want to make claims before the rig has been tested in competition, but he says it has “shot groups at 600 and 1000 yards that would be very competitive.” We promised not to publish group sizes yet, but we can tell you that at 600 yards in good conditions it drilled some “scary small” 5-shot groups, well, well under 1/4 MOA.
Here’s a cleverly-designed product that adds versatility to any rifle with a front sling swivel stud. This clever Stud Rail Adapter (SRA) allows you to mount a Picatinny Rail on a sling swivel stud. With the SRA in place, you can attach any accessories that clamp to a Pic rail, such as lights, lasers, pistol grips, or rail-affixed tactical bipods. And look carefully — the SRA’s designers included a sling swivel at the inboard end of the unit. That way you can mount Picatinny-rail accessories and still use your carry sling.
Sold by Harrisbipods.com, the SRA Stud Rail Adapter retails for $47.85. This adapter is crafted in the USA by MIM Mfg. from 6061 TG Aluminum with a black anodized finish. This can be used with the RBA-1 and RBA-2 bipod adapters.
This adapter is a useful invention, particularly for those who might want to mount a light or clamp-on bipod to a varmint rifle. Most hunting rifles have a front sling swivel stud and there is now a very wide selection of Picatinny-rail-mounted accessories.
NOTE: HarrisBipods.com is a web retailer. This is NOT Harris Engineering, the manufacturer of Harris bipods. HarrisBipods.com does sell the full line of Harris bipods and most Harris accessories.

The Canadian Precision Rimfire Series (CRPS) is a non-profit organization founded in 2018 to promote competitive shooting sports for Canadians coast-to-coast. The CRPS now hosts 100+ events with over 1500 competitors annually. The CRPS was created to provide shooters across Canada with a challenging environment to test their precision shooting skills using .22 LR rimfire rifles. Matches are held throughout Canada to allow all Canadians a chance to see how they “stack up” against the rest of the country. The CRPS has three divisions: Open Class; Production Class (Rifle $500 USD MSRP max, Optics $700 USD MSRP max); and Youth Class. These events give shooters of all budgets an opportunity to test their skills and equipment under demanding conditions.
Using a PRS-style match format, with timed stages, competitors engage 1-5 steel targets per stage. Targets are placed from 50 to 300 meters. Target sizes range from 1/2″ to 9″. The steel targets are shot from a variety of positions. Many stages involve a challenging set of platforms or barricade rests.

RCBS offers a series of premium MatchMaster Competition Dies. These are available in Full-Length Sizing, Neck Sizing, and Seating configurations. These new MatchMaster dies are notable for four features:
1. The Competition Seating Die has a “view-port” for the bullet.
2. The Competition Seating Die features a self-centering, free-floating bullet-seating stem.
3. Expanders are titanium-nitride coated for reduced friction. Both the Neck-Sizing and FL-Sizing dies come with TiN expanders for smoother case extraction and reduced brass build-up on the expander.
4. RCBS is offering its own precision-machined Neck Bushings.
No More Mashed Fingers When Seating Bullets
RCBS notes: “Reloaders will love that they can end smashed fingers and misaligned bullets with the specially-designed bullet window [on the Seating Die]. And users can fine-tune any load … with the micrometer-adjustable, free-floating, self-centering bullet seating stem.”
RCBS Product Manager Will Hemeyer explained that the new Competition Seater is a game-changer. “What sets the MatchMaster Seating Die apart from the competition is a bullet-seating window with bullet-retaining system. Simply place the bullet in the window and raise the case into the die to seat the bullet. Couple this with a micrometer-adjustable, free-floating, self-centering bullet-seating stem[.]”

Why Use Expander with Bushing Dies?
Some viewers of Gavin’s video asked if an expander is superfluous when using neck-bushing dies. The answer is “it depends”. The bushings reduce neck diameter from the OUTSIDE. The expander should make the INSIDE of the neck perfectly round. Some hand-loaders prefer to take the necks down a couple thousandths below final loading diameter, then finish the job with an expander. That ensures the INSIDE of the case neck is perfectly concentric. This can be particularly useful for brass that has somewhat inconsistent neck-wall thickness. Bottom line, you can run these dies without expanders if you want, but that option is available. The expander is also removable so the assembly can be used for de-capping only.
MactchMaster Neck-Sizing Only Die
The MatchMaster Neck Sizing Die Set also uses RCBS neck bushings to control neck tension while not changing the body dimensions of fired cases. Frankly we strongly recommend that you full-length size your rifle rounds, but we acknowledge that some hand-loaders prefer to neck size for some applications. The MatchMaster Neck Sizing Dies do include a titanium-nitride coated expander, just like the FL-sizing MatchMaster dies.
Gunsmith/stockmaker Doan Trevor created a lovely, one-of-a-kind silhouette stock for an Anschutz rimfire action. Built as a true custom design, this stock combines ideal standing position ergonomics with light weight — the entire stock weighs a mere two pounds. This project really showcases Doan’s remarkable skills with wood. Read the full story about this project (with more photos) at DoanTrever.com.
Doan explains his design process: “A customer came to me wanting to know if I could build a silhouette stock that was 2 pounds or less. I used the Koa wood because it is a lower specific gravity than Walnut (which makes it lighter) and stronger. I was still able to use pillar bedding and keep the weight down. The fore-end could be shortened to reduce the weight even more.
Since the drops on a silhouette rifle are different than a prone rifle, I kept the pistol grip from the prone rifle which is comfortable and tried to come up with a higher cheek piece and more drop to the buttplate. All of this required lots of hand carving.”
Vudoo Gun Works has introduced its new Vudoo Three 60 three-lug repeater rifle. This is an impressive repeater rimfire rifle. The Vudoo Three 60 features a 3-lug bolt with a 60-degree throw and a 12 O’Clock ignition. This combination uses the same internal 3-lug geometry of the Vudoo V22s single shot action, ensuring light bolt lift along with smooth and consistent bolt alignment with the bore.
Users will enjoy the same accuracy performance known across the entire Vudoo family of rifles. The Vudoo Three 60 will be offered alongside the already popular V22 two lug repeater, V22m Magnum repeater, and V22s Single Shot Target Rifle.
The Patented Vudoo Three 60 Rimfire repeater action was engineered in response to requests for a 3-lug 60-degree bolt throw repeater action. Like all current Vudoo V22 actions, the Three 60 fire control group offers a toolless disassembly by way of a unique bayonet-style locking system between the shroud, bolt body, and bolt nose.

New Vudoo Three 60 Should Please 3-Lug Centerfire Rifle Owners
Paul Parrott, Vudoo Gun Works CEO, explains: “The Three 60 configuration has been highly requested by our Vudoo family and [is] the logical next step in our product line. Is it more accurate than the 2-lug version? No, it’s just the next evolution in our ongoing commitment to redefine rimfire. The guys who will love it most are 3-lug centerfire shooters and those needing more bolt/optic clearance.”

Barrett Firearms Manufacturing has been awarded a five-year $49.9 million contract under the U.S. Army Precision Sniper Rifle program with its MRAD (Multi-Role Adaptive Design) MK22 MOD 0 rifle, paired with a Leupold Mark 5 HD scope. The MK22 system will replace several current U.S. Army sniper rifles.
Designed for precision and modularity, the MK22 provides cartridge-choice flexibility within the highly successful MRAD rifle platform. By switching barrels, this multi-caliber bolt action rifle can be used with 7.62x51mm, .300 Norma Magnum (NM) and .338 Norma Magnum (NM) cartridge types, based on the mission. The Army stated that the new MRAD MK22 rifle “increases stand-off distances ensuring overmatch against enemy counter sniper engagements and increases sniper capability.” More Details HERE.
The Mark 22 comes standard with a folding stock and an action/chassis system that easily allows changeable barrels. Barrels can be quickly swapped by loosening two Torx-30 screws. The MK22 spec sheets list a 2.5-lb trigger pull. The complete field package weigh 24 pounds, including rifle, Leupold Mark 5 HD scope, two magazines, and disassembly tool.
Civilian Version of Mark 22 Will Be Available
For a limited time, Barrett will offer Mark 22 rifles with the serious price of $16,770. Yes you can buy a pretty nice used car for that. But military-grade quality doesn’t come cheap. The Leupold Mark 5 HD optic adds $2,300 to the price.
According to SofRep.com : “The MRAD … has been primarily designed for the U.S. Special Operations Command’s (SOCOM) Advanced Sniper Rifle (ASR) program that seeks to replace the current sniper rifles with new, more effective ones. The ASR program was stipulated for a bolt-action rifle that could use three different calibers (the .300 Norma Magnum, .338 Norma Magnum, and 7.62 NATO). Further, it requires the sniper rifle to be able to hit with accuracy targets at a minimum of 1,500 meters. The rationale behind the multiple calibers is to give shooters the ability to tailor their shots according to the situation they face on the battlefield.”
