NEW Titanium Self-Timing Muzzle Brake from Ryan Pierce

Self-timing muzzle muscle brake titanium Ti 5-port hunting rifle

Here is something shiny and new for the guy who has to have the latest hardware. Ryan Pierce of “PiercisionRifles.com makes very effective muzzle brakes (aka “Muscle Brakes) that have a clever “self-timing” feature, that allows them to be fitted to multiple rifle barrels. Most of Ryan’s Muscle Brakes are crafted from steel, but he just introduced a slick 5-Port Self-Timing Titanium Brake. Ryan says the self-timing feature of this design allows the buyer to use the same brake on all rifles with the same thread pitch on the muzzle. Check it out:

Self-timing muzzle muscle brake titanium Ti 5-port hunting rifle

Ryan reports: “Got the new TITANIUM self-timing 5-port ‘Muscle’ brake spun up on a 300 Norma improved I chambered this morning. The barrel and brake weighs 3.0 pounds total. At just 3.5 ounces, the titanium brake is 3 ounces lighter than the steel version. The Titanium Muscle brake is available in 5/8×24 and 3/4×24 threads. I have some ready to ship in 3/4×24 threads. I’ll have another batch ready to ship in a week or so in 5/8×24 threads.”

Who needs a Titanium brake? Well if you’re putting together a high-tech ultralight hunting rig, this is a nice finishing touch. When shooting off-hand, less weight on the end of the barrel really makes a difference. And if you’ve gone to the expense of fitting a lightweight carbon fiber-wrapped barrel, it may make sense to finish it off with an ultralight titanium brake.

How well does it work? Ryan says with this brake on his 10-lb .300 Norma Improved rifle he can see bullet impacts at 400 yards. That’s with 230-grain bullets launched at 3000+ FPS.

NOTE: Currently these brakes are sold in a 5-port version only. Ryan offers 3-port brakes in steel, but says the weight savings would be only 1 ounce with a Titanium 3-port.

2019 CMP Springfield M1A Match at Camp Perry

The 13th annual Springfield Armory M1A Match will take place during the 2019 CMP National Rifle Matches. The CMP will host the event on Sunday, August 4, 2019, the day after the John C. Garand Match. Competitors of all experience levels are encouraged to bring their M1A rifles to Camp Perry and compete. Online Registration is still possible. The match is open to all individuals ages 12 and above. For more information contact the CMP at competitions@thecmp.org or call 419-635-2141 ext. 724 or 714.

Springfield M1A match high power rifle

The Springfield Armory M1A match began with one man’s idea and passion. Springfield Armory’s Mike Doy witnessed the waning of classic M1 Garand and M1A rifles from the competitive High Power firing lines. “I really wanted to get those M1A rifles out of safes and closets and back out onto the field. So 11 years ago, I promoted the idea of running an M1A-specific match at Camp Perry. That first year we had over 600 competitors and spectators.” Now the match offers some of the biggest pay-outs at Camp Perry. In recent years, Springfield Armory has donated over $25,000 worth of cash and prizes, including a $2,000 cash award to the overall winner.

Sunday GunDay: Shiraz Balolia’s F-Class Lowboy Stock Project

Shiraz Balolia Grizzly F-Class Laminated stock .300 WSM competition rifle gunsmithing gunstock lathe mill

Lowboy F-Class Gunstock Conversion

Project by Shiraz Balolia, President of Grizzly Industrial
The lowboy stock you see above started as an experiment. I had an extra Masterclass F-Class stock that had gone through two actions, four beddings, and multiple modifications over the years. I figured that there was nothing to lose if the experiment did not work out.

After deciding on the design, the stock was carefully leveled in every direction and milled to the precise dimensions for attaching the side pieces, which would be glued to the original stock.

Curly Maple and Bubinga wood were laminated to get the exact thickness of the side pieces so that the total width of the fore-end would be just under the total width allowed for F-Open stocks.

Two guide pins made of Bubinga were drilled through each side so that the sides would not move when glued to the milled stock.

Once the sides were glued to the blank, the stock was once again trued on the mill so it was perfectly flat and square with the back (see below).

The stock was then sent to Keith Weill at KW Precision who did an incredible bedding job on the new BAT M action. The stock was then sent out for spraying a clear finish. Normally I spray my own stocks, but I did not have time for this stock, so that part was subbed-out. The finger grooves and “Shiraz” inlay had been done by me a few years prior during the old stock’s heyday.

Modified Stock Has Significantly Lower Center of Gravity
The rifle was then assembled, a March 10-60x56mm High Master scope was installed, and break-in was completed on the new barrel. At the range, the stock performed great. The stock rides one-half-inch lower in the front bag and really feels good.

Bartlein Barrel Is Chambered in .300 WSM
I was pleased to find that the Bartlein barrel I have on this gun cleaned up very well during barrel break-in and this “experiment” may turn into this being one of my best-performing guns. All of my F-Open match guns are .300 WSM (Winchester Short Magnum), and so is this one.

Sunday GunDay: “We the People” .284 Shehane F-Open Rifle

.284 Winchester Shehane F-Open F-Class 7mm Berger Panda F-Class Blake Machine
Jason Cohen’s “We the People” patriotic .284 Shehane F-Class rifle. It has already demonstrated great promise, scoring second place in its very first match, a 3×20 at 1000 yards in Wyoming.

Rifle Report by Jason Cohen
The rifle began its life as a Will McClosky Cerus stock. I approached Will at the Berger SW Nationals about a rifle I wanted to build. I wanted to do something different — PAINT it. He said he had just the stock that I could use, and sent that to Bryan Blake at Blake Machine. I chose Bryan for two reasons — first, I have shot with him a few times at National matches and he is approachable and very helpful. Second I visited his shop during the SWN in February and liked what I observed and how he approached things. Bryan never seems to be happy with the status quo. He is always trying new ideas.

I noticed that Bryan had been adding aluminum rails to the front of Cerus stocks to lower the center of gravity and improve tracking. I asked him to modify my stock and fit it with the new forearm rails, shown in the photo below. I sent him a Panda F-Class action with a +20 MOA Picatinny rail. Bryan did all the stock work and fitted the action, rails, and RAD recoil pad. Everything turned out flawless.

.284 Winchester Shehane F-Open F-Class 7mm Berger Panda F-Class Blake Machine

The barrel is a Blake Machine 1:8″-twist finished at 32 inches. It was fitted to my action by Dale Woolum of Woolum Accuracy. Dale chambers all my barrels on all my rifles. Dale also threaded the barrel for a Woolum Accuracy tuner. This has proven to be a valuable tool in my load development. On this build, I am trying a Bix’N Andy trigger for the first time.

.284 Winchester Shehane F-Open F-Class 7mm Berger Panda F-Class Blake Machine

The 284 Shehane has a proven record of accomplishments and that is why I have chosen it. I use Lapua brass (6.5-284 necked-up), CCI BR-2 primers, Hodgdon H4350 powder, and Berger 184gr bullets. All these components have been a successful combination that has worked flawlessly in my other rifle.

.284 Shehane Load Development
Load development for me starts with each new barrel. I screw on the new barrel, fire 25 rounds of whatever I have left over and then clean it. I push out to 600 yds and do a ladder test in round-robin format. I start 0.6 grains lower than my last charge that worked. I work up from that reduced charge weight in increments of 0.3 grains. The paper tells the rest of the story. Once I get something that works well at 600 yards I go back in work around that by 0.1 grains. After that I play a little with seating depth and look for a change. I will occasionally mess with the tuner and tighten things up if possible.

.284 Winchester Shehane F-Open F-Class 7mm Berger Panda F-Class Blake Machine

About the Patriotic Paint Job
So I had the idea of painting the stock because there are so many wood stocks with clear coat these days. Unless you really get some exotic woods they all seem to blend together. I have nothing against clear-coated wood, but I wanted something different, as this was my first all-wood rifle. (For short-range benchrest, I was shooting a Bob Scoville carbon stock and Terry Leonard laminate).

We started with all white on the stock and came up with the idea of an American Flag on the buttstock. I was thinking of ribbons on the front in red and blue but we could not get the layout right. Then the idea of “We the People” popped into the head. My painter said “awesome!” and he was able to airbrush the stock with a little yellow and brown to give it that vintage paper look.

.284 Winchester Shehane F-Open F-Class 7mm Berger Panda F-Class Blake Machine

The front rest is a SEB Max (see above). I chose the Max because I was shooting Group Benchrest first then made the transition to F-Class. This rest proves to be versatile in all my shooting — Short- and Long-Range Benchrest AND F-Class. The rear bag is a Edgewood EDGEbag Gator. The gun gets transported in a Pelican Hard case when I travel. Locally, I use a Champions Choice soft bag.

Jason Jumped to Open Class after Starting with F-TR
This “We the People” rifle will be one of my primary rifles for F-Open competition. I will run it through its paces shortly and see how well it does. I have high hopes of it being an great gun. I shoot primarily local and regional matches — Colorado, Wyoming, and possibly Nebraska this summer. I will travel to the F-Class Nationals in Raton as well. I used to shoot F-TR before this and made the transition to Open last season. This is my second season shooting F-Open. 2018 was my first National event and was a learning experience for me. But I was hooked after that match.

Tips for F-Class Competitors
Get some good equipment and eliminate having issues that can be caused by budget builds. It’s OK to be frugal, but sometimes cutting corners will cause you more problems and have you chasing your tail. If you’re looking for the “recipe for success”, get a good action plus a top-tier barrel and great glass.

.284 Winchester Shehane F-Open F-Class 7mm Berger Panda F-Class Blake Machine

The .284 Shehane — Accurate and Forgiving Wildcat
The 284 Shehane is amazing, very forgiving and not temperamental. I choose this because I really did not know otherwise and was steered to the Shehane by a friend. Its proven track record helped as well. Straight .284 or Shehane — you cannot go wrong. I run a 184gr Berger at about 2850 FPS and get great brass life in my other rifles. I usually start to consider tossing the brass around 15 firings. Primer pockets start to get a little looser and the brass seems to need more sizing than the newer brass with less firings.

Big News — Savage Arms Sold Off by Vista Outdoor

Savage Arms Management Sale Vista Outdoor divestiture sell-off buy-out

Big news for the shooting community! Just six years after it acquired Savage Arms, outdoor industry mega-corp Vista Outdoor is selling off Savage Arms. The firearms-maker will be acquired by a private investment group led by Savage’s current management. When the sale is complete, Vista Outdoor, parent company of dozens of outdoor brands such as Bushnell, Bell Helmets, CCI, Camelback, Federal, RCBS, and Weaver, will no longer produce firearms of any kind. The sell-back to the Savage management group will include Stevens Arms*, which primarily produces shotguns.

There were multiple reasons given for the sale, which include:
1. Cutting costs, reducing corporate debt, and consolidating operations at Vista Outdoor.
2. Focusing more on the ammunition brands Alliant, CCI, Speer, and Federal.
3. Giving Vista Outdoor’s “ammunition brands flexibility to work with any industry partner”.

In addition, we suspect that, given the current political climate and media antagonism towards gun-makers, Vista Outdoor’s leadership deemed that owning Savage was bad for the company’s overall image. The potential profits from Savage were simply not worth the negative press as well as the potential liabilities from gun-related lawsuits.

By the Numbers: Vista Outdoor acquired Savage Arms (and Stevens) in July 2013 for $315 million. The July 2019 sell-off of Savage Arms (and Stevens) for $170 million represents a $145 million loss for Vista Outdoor. That’s not a good business model.

Savage Arms Management Sale Vista Outdoor divestiture sell-off buy-out

Founded in 1894, Massachusetts-based Savage Arms is one of America’s oldest gun-makers. While it has produced a wide variety of firearms over the past 125 years, Savage is now best known for its affordable bolt-action hunting rifles that feature barrels attached by a barrel-nut. In recent years, Savage has also moved aggressively into the “black rifle” market producing its MSR series of AR-platform rifles in a variety of chamberings. Savage also produces a popular semi-auto Rimfire rifle, the Savage A17/A22 series.

Savage Arms Management Sale Vista Outdoor divestiture sell-off buy-out

Here is the official Press Release covering Vista Outdoor’s sale of Savage Arms to a group of investors headed by Al Kasper, Savage’s President and CEO (emphasis added):

Vista Outdoor Announces Sale of Savage Brand
Vista Outdoor Inc. (“Vista Outdoor”) (NYSE: VSTO) announced today that it has completed the sale of the legal entity operating its Savage Arms and Stevens firearms brands to a financial buyer for a total purchase price of $170 million, comprised of $158 million paid at closing and $12 million to be paid upon maturity of a five-year seller note issued by the buyer to Vista Outdoor in connection with the transaction.

The sale is part of Vista Outdoor’s previously announced transformation plan, which outlined the intent to reshape the company’s portfolio by cutting costs, consolidating leadership, paying down debt, and divesting certain brands, including both its eyewear brands and firearms brands, in order to pursue growth in product categories where the company believes it can be market leaders. As the company now looks forward, the focus is on ammunition, hunting and shooting accessories, hydration bottles and packs, outdoor cooking products, and cycling/ski helmets and accessories.

“Divesting our Savage brand was a key aspect of our transformation plan,” said Chris Metz, CEO of Vista Outdoor. “While it was a difficult decision to sell such an iconic brand, I remain confident that this was the correct choice to help Vista Outdoor grow in those categories where we can have leadership positions. Savage is a fantastic business, and it deserves to continue to evolve into other firearms categories. At this time, however, we simply do not have the resources to transform Savage into the full-service firearms company that it deserves to be and, therefore, we determined the brand would be better off with a different owner. We’re excited to see Savage reach its full potential under new ownership.”

Savage was acquired by Vista Outdoor’s predecessor, ATK, in 2013. ATK’s sporting business – which included Savage, Bushnell, Federal and CCI Ammunition, and dozens of other hunt/shoot accessories brands, spun off in 2015 to become Vista Outdoor.

“The Savage acquisition helped create Vista Outdoor, and we’re grateful for all the success the brand brought to our company over the past six years,” said Metz. “However, this divestiture now gives our ammunition brands flexibility to work with any industry partner to create the best products and meet our consumers’ needs.”

At closing, Vista Outdoor received gross proceeds from the divestiture of $158 million. Vista Outdoor will use the net after-tax proceeds of the sale to repay outstanding indebtedness.

“Reducing our debt is a key part of turning around our business,” said Metz. “Selling Savage and further reducing our overall leverage will improve our financial flexibility and better position the company for long-term growth. We’ve now rebuilt the company’s foundation to provide a more stable base upon which to grow. We have a portfolio of brands that all have the potential to be strong, market leaders in their respective categories and I’m proud of my team’s efforts in reshaping the portfolio over the course of the past year.”


*American firearms manufacturer J. Stevens Arms & Tool Company, now part of Savage Arms, introduced the .22 Long Rifle cartridge in 1887. Savage Arms was founded in 1894 by Arthur Savage in Utica, New York. Within 20 years Savage was producing rifles, handguns, and ammunition. Savage introduced the first hammerless lever-action rifle, the Model 1895, derived from Arthur Savage’s Model 1892 rifle that he had designed for Colt.

X-Ray Views Show How Rem 700 and AR Actions Work

3d firearms modeling gun CGI software encylopedia gun disassembly

Ever wish you could look inside your rifle, to see how the trigger and fire-control system work? Well now that is possible with the magic of 3D computer graphics. Modern software allows detailed “cutaway” side-views (see below), as well as 3D views with 360° rotation. The software can also provide X-Ray-type views into the gun’s internals — as you can see above. And computer animation can show the complete firing process from trigger pull to chambering of the next round.

Rem 700 Cutaway View from Right Side
3d firearms modeling gun CGI software encylopedia gun disassembly

This article covers two different animations — a bolt-action, and a self-loading “gas gun”. The first video features the popular Rem 700 action, probably the most successful American bolt-action ever created. The second video offers a lengthy exploration of the AR15/M16 platform.

READERS — Take the time to watch these videos! The Rem 700 animation is really outstanding! EVERY bolt-action shooter should watch this video all the way through.

Cutaway 3D Animation of Rem 700 Action — Watch Video

The Model 700 series of bolt-action rifles have been manufactured by Remington Arms since 1962. All are based on basically the same centerfire bolt action. They are typically sold with an internal magazine depending on caliber, some of which have a floor-plate for quick-unloading, and some of which are “blind” (no floor-plate). The rifle can also be ordered with a detachable box magazine. The Model 700 is a development of the Remington 721 and 722 series of rifles, which were introduced in 1948.

3d firearms modeling gun CGI software encylopedia gun disassembly

The Rem 700 is a manually-operated bolt action with forward, dual opposed lugs. It features “Cock On Opening”, meaning the upward rotation of the bolt when the rifle is opened cocks the firing pin. A cam mechanism pushes the firing pin’s cocking piece backward. The bolt face is recessed, fully enclosing the base of the cartridge. The extractor is a C-clip sitting within the bolt face. The ejector is a plunger on the bolt face actuated by a coil spring. The bolt is of 3-piece construction, brazed together (head, body. and bolt handle). The receiver is milled from round cross-section steel.

The AR platform rifles are a semi-automatic version of the M16. These feature distinctive upper and lower receivers which can be readily separated via front and rear pins. The upper includes the barrel, handguard, forward gas tube, and bolt assembly, while the lower contains grip, trigger group, fire selector, and mag well. In addition the lower is attached to the stock which encloses the buffer assembly.

The original ArmaLite AR-15 was a select-fire, air-cooled, gas-operated, magazine-fed rifle designed by American gun manufacturer ArmaLite in 1956. It was based on Armalite’s AR-10 rifle chambered for the 7.62×51 NATO (.308 Win). In 1959, ArmaLite sold its rights to the AR-10 and AR-15 to Colt. Some key modifications were made — most notably, the charging handle was re-located from under the carrying handle to the rear of the receiver. The redesigned rifle was adopted by the U.S. military as the M16 carbine, which went into production in March 1964.

Figure Out Exact Barrel Weight with Pac-Nor Calculator

Online Pac-Nor Barrel Calculator

Can you guess what your next barrel will weigh? In many competition disciplines, “making weight” is a serious concern when putting together a new match rifle. A Light Varmint short-range Benchrest rifle cannot exceed 10.5 pounds including scope. An F-TR rifle is limited to 18 pounds, 2 oz. (8.25 kg) with bipod.

One of the heaviest items on most rifles is the barrel. If your barrel comes in much heavier than expected, it can boost the overall weight of the gun significantly. Then you may have to resort to cutting the barrel, or worse yet, re-barreling, to make weight for your class. In some cases, you can remove material from the stock to save weight, but if that’s not practical, the barrel will need to go on a diet. (As a last resort, you can try fitting a lighter scope.)

Is there a reliable way to predict, in advance, how much a finished barrel will weigh? The answer is “yes”. PAC-NOR Barreling of Brookings, Oregon has created a handy, web-based Barrel Weight Calculator. Just log on to Pac-Nor’s website and the calculator is free to use. Pac-Nor’s Barrel Weight Calculator is pretty sophisticated, with separate data fields for Shank Diameter, Barrel Length, Bore Diameter — even length and number of flutes. Punch in your numbers, and the Barrel Weight Calculator then automatically generates the weight for 16 different “standard” contours.

Calculator Handles Custom Contours
What about custom contours? Well the Pac-Nor Barrel Weight Calculator can handle those as well. The program allows input of eight different dimensional measurements taken along the barrel’s finished length, from breech to muzzle. You can use this “custom contour” feature when calculating the weight of another manufacturer’s barrel that doesn’t match any of Pac-Nor’s “standard” contours.

Caution: Same-Name Contours from Different Makers May Not be Exactly the Same
One final thing to remember when using the Barrel Weight Calculator is that not all “standard” contours are exactly the same, as produced by different barrel-makers. A Medium Palma contour from Pac-Nor may be slightly different dimensionally from a Krieger Medium Palma barrel. When using the Pac-Nor Barrel Weight Calculator to “spec out” the weight of a barrel from a different manufacturer, we recommend you get the exact dimensions from your barrel-maker. If these are different that Pac-Nor’s default dimensions, use the “custom contour” calculator fields to enter the true specs for your brand of barrel.

Smart Advice — Give Yourself Some Leeway
While Pac-Nor’s Barrel Weight Calculator is very precise (because barrel steel is quite uniform by volume), you will see some small variances in finished weight based on the final chambering process. The length of the threaded section (tenon) will vary from one action type to another. In addition, the size and shape of the chamber can make a difference in barrel weight, even with two barrels of the same nominal caliber. Even the type of crown can make a slight difference in overall weight. This means that the barrel your smith puts on your gun may end up slightly heavier or lighter than the Pac-Nor calculation. That’s not a fault of the program — it’s simply because the program isn’t set up to account for chamber volume or tenon length.

What does this mean? In practical terms — you should give yourself some “wiggle room” in your planned rifle build. Unless you’re able to shave weight from your stock, do NOT spec your gun at one or two ounces under max based on the Pac-Nor calculator output. That said, the Pac-Nor Barrel Weight Calculator is still a very helpful, important tool. When laying out the specs for a rifle in any weight-restricted class, you should always “run the numbers” through a weight calculator such as the one provided by Pac-Nor. This can avoid costly and frustrating problems down the road.

Sunday Gunday: Bart’s 6PPC Drills Five Shots in .088″ at 200!

Bart Sauter Bart's Bullets 200-yard East Meet West
This would be an amazing group at 100 yards. But this 5-shot bughole was shot at TWO HUNDRED yards in competition by Bart Sauter of Bart’s Custom Bullets. And he did it with a borrowed barrel!

Be amazed. This five-shot group was shot at 200 yards in competition by bullet-maker Bart Sauter. Bart shot this astounding group with his 10.5-lb Light Varmint benchrest rifle at the recent East-West Match in St. Louis, Missouri. Had Bart been shooting an IBS match, this would have been a new IBS World Record, beating the .091″ by David Farrar in 2006. This .088″ group missed the NBRSA 200-yard 5-shot group record by a whisker — .013″ (thirteen thousandths). The listed NBRSA LV 200-yard Group record is 0.075″ shot by Johnnie Stewart a decade ago.

New record or not, this is one remarkably impressive group, shot by one very talented shooter and bullet-maker. Bart tells us he initially “held center” for the first three shots in the group. Then, watching his wind flags he noticed slight increase in the left-to-right condition, so he held 0.200″ to the left on shot 4 and it worked. Before shot 5, Bart detected another slight change, so he held 0.300″ left for the fifth and final shot. He explained: “If I had not held off for those last two shots, this group would have been about a flat four (0.400″).” Well done Bart!

“First three … bang bang bang … all went in one hole. Then I held left on shot 4 and it worked. On the last shot I held a little more, got lucky and it went in.” — Bart Sauter

In our Shooter’s Forum, Bart posted “This is my personal best-ever 5-shot group at 200 yards. I knew it was small, but was shocked to see it was a Zero! This will be a range record and record for the East/West match. Last group of the day! A nice way to end the match!”

Here is the 6PPC LV rifle that shot the .088″ group. Yes that’s a concrete shooting bench inside a pretty nice cabin with hunting trophies on the walls. Bart explained: “We reload and shoot out of the Monkey Hut, especially during the winter. Most of the time we shoot outside at 100/200 from a a three-bench range.

Amazing Group Shot with Borrowed Krieger Barrel!
There’s a very interesting side-note to this story. You see Bart doesn’t even own the Krieger barrel that delivered this amazing .088″ 200-yard group. That’s right this superb barrel was a “loaner” — borrowed from Bart’s buddy Gary Sullivan. [Editor: Oh that we could all be so lucky with borrowed components.] With Sullivan’s blessing, Bart has since loaned the barrel yet again to ace Billy Stevens, who will be using it at the World Benchrest Championship in Canada, July 14-21, 2019.

Here is Bart’s target with a bullet removed. Bart was shooting his own 6mm 68gr Avenger bullets, a double-radius ogive design. The Avengers were seated about .004″ away from the lands: “I tried going into the lands and that didn’t seem to work, then I backed it off four thousandths [from contact] and the rifle liked that.” Bart drove those 68gr Avengers with a stout load of Accurate LT30 powder running 3407 FPS.

Bart’s Comments on His Components and Accessories

OPTICS — Bart likes his new 40x45mm IOR-Valdada Benchrest Scope. He says that, so far, it has proved very reliable and holds zero exceptionally well. This new design features a worm drive side-focus, oversized ocular with true +/- diopter adjustment, long eye relief, and fast-focusing reticle. The 40X Valdada also boasts superb HD “double-compressed” Schott glass from Germany.

TUNER — Bart says the Bukys TSI Tuner definitely helps. He notes that once he finds the “sweet spot” for his barrel he can normally leave it alone: “With that type of tuner, I have to be in a very dire straight to move it. Normally I will set it for the lifetime of the barrel.”

REAR BAG — Bart’s rear bag is an unusual Edgewood with softer gray leather. He says this was a special order by Bruno Shooters Supply. Bart likes how the rear bag works with his carbon-stocked 10.5-lb rifle: “With PPCs we ‘ride on the ears’ — this older bag just seems to work really well for that style.”

SUPER FEET — Bart told us he uses Benchsource Super Feet for his front rest: “The bench tops at St Louis are very slick. Before I set up I’ll use a spray bottle with water and wet the bench where the Super feet and rear bag will go. This really helps to keep things from sliding around!”
