Barrel-maker Dan Lilja’s website, RifleBarrels.com has an excellent FAQ page that contains a wealth of useful information. On the Lilja FAQ Page you’ll find answers to many commonly-asked questions. For example, Dan’s FAQ addresses the question of barrel life. Dan looks at factors that affect barrel longevity, and provides some predictions for barrel life, based on caliber, chambering, and intended use.

NOTE: This article was very well-received when it was first published. We are reprising it for the benefit of readers who missed it the first time.

Dan cautions that “Predicting barrel life is a complicated, highly variable subject — there is not a simple answer. Signs of accurate barrel life on the wane are increased copper fouling, lengthened throat depth, and decreased accuracy.” Dan also notes that barrels can wear prematurely from heat: “Any fast varmint-type cartridge can burn out a barrel in just a few hundred rounds if those rounds are shot one after another without letting the barrel cool between groups.”

Q. What Barrel Life, in number of rounds fired, can I expect from my new barrel?

A: That is a good question, asked often by our customers. But again there is not a simple answer. In my opinion there are two distinct types of barrel life. Accurate barrel life is probably the type most of us are referencing when we ask the question. But there is also absolute barrel life too. That is the point where a barrel will no longer stabilize a bullet and accuracy is wild. The benchrest shooter and to a lesser extent other target shooters are looking at accurate barrel life only when asking this question. To a benchrest shooter firing in matches where group size is the only measure of precision, accuracy is everything. But to a score shooter firing at a target, or bull, that is larger than the potential group size of the rifle, it is less important. And to the varmint hunter shooting prairie dog-size animals, the difference between a .25 MOA rifle or one that has dropped in accuracy to .5 MOA may not be noticeable in the field.

The big enemy to barrel life is heat. A barrel looses most of its accuracy due to erosion of the throat area of the barrel. Although wear on the crown from cleaning can cause problems too. The throat erosion is accelerated by heat. Any fast varmint-type cartridge can burn out a barrel in just a few hundred rounds if those rounds are shot one after another without letting the barrel cool between groups. A cartridge burning less powder will last longer or increasing the bore size for a given powder volume helps too. For example a .243 Winchester and a .308 Winchester both are based on the same case but the .308 will last longer because it has a larger bore.

And stainless steel barrels will last longer than chrome-moly barrels. This is due to the ability of stainless steel to resist heat erosion better than the chrome-moly steel.

Barrel Life Guidelines by Caliber and Cartridge Type
As a very rough rule of thumb I would say that with cartridges of .222 Remington size you could expect an accurate barrel life of 3000-4000 rounds. And varmint-type accuracy should be quite a bit longer than this.

For medium-size cartridges, such as the .308 Winchester, 7×57 and even the 25-06, 2000-3000 rounds of accurate life is reasonable.

Hot .224 caliber-type cartridges will not do as well, and 1000-2500 rounds is to be expected.

Bigger magnum hunting-type rounds will shoot from 1500-3000 accurate rounds. But the bigger 30-378 Weatherby types won’t do as well, being closer to the 1500-round figure.

These numbers are based on the use of stainless steel barrels. For chrome-moly barrels I would reduce these by roughly 20%.

The .17 and .50 calibers are rules unto themselves and I’m pressed to predict a figure.

The best life can be expected from the 22 long rifle (.22 LR) barrels with 5000-10,000 accurate rounds to be expected. We have in our shop one our drop-in Anschutz barrels that has 200,000 rounds through it and the shooter, a competitive small-bore shooter reported that it had just quit shooting.

Remember that predicting barrel life is a complicated, highly variable subject. You are the best judge of this with your particular barrel. Signs of accurate barrel life on the wane are increased copper fouling, lengthened throat depth, and decreased accuracy.

Benchrest Barrel Life — You May Be Surprised
I thought it might be interesting to point out a few exceptional Aggregates that I’ve fired with 6PPC benchrest rifles with barrels that had thousands of rounds through them. I know benchrest shooters that would never fire barrels with over 1500 shots fired in them in registered benchrest matches.

I fired my smallest 100-yard 5-shot Aggregate ever in 1992 at a registered benchrest match in Lewiston, Idaho. It was a .1558″ aggregate fired in the Heavy Varmint class. And that barrel had about 2100 rounds through it at the time.

Another good aggregate was fired at the 1997 NBRSA Nationals in Phoenix, Arizona during the 200-yard Light Varmint event. I placed second at this yardage with a 6PPC barrel that had over 2700 rounds through it at the time. I retired this barrel after that match because it had started to copper-foul quite a bit. But accuracy was still good.

Want to shoot better scores at your next match? Here’s a smart, inexpensive do-it-yourself project from the good folks at Criterion Barrels. For less than a dollar or two in materials, in just a few minutes you can create a handy, effective mirage shield, custom-fitted to your favorite rifle.

All precision shooters should be familiar with mirage, a form of optical distortion caused primarily by variations in air temperature. Savvy shooters will use mirage as a valuable tool when gauging wind speed and direction. Natural mirage is unavoidable, but there are many techniques designed to limit its influence in long-range marksmanship.

A form of mirage can be produced by the barrel itself. Heat rising from the barrel may distort sight picture through your optics, leading to erratic results. Mirage caused by barrel heat can be reduced dramatically by a simple, light-weight mirage shield.

How to Make a Mirage Shield

1. Measure the distance from the end of the receiver or rail to the crown of the barrel.

2. Using a pencil and ruler, measure the same distance and mark an even line across the blind.

3. Cut across the line using scissors or a box cutter, shortening the blind to the required length. (Remember, measure twice, cut once!)

4. Expose the adhesive backing on the loop side of the Velcro. Center and apply the Velcro strips on the barrel at regular intervals.

5. Expose the adhesive backing of the fuzzy side of the Velcro.

6. Place the blind on the upper side of the barrel. Apply downward pressure. Once the Velcro has secured itself to the barrel, separate the two sides. Proceed to mold both sides of the Velcro to fit the contour of their respective surfaces.

7. Reaffix the blind. Barrel related mirage is now a thing of the past!

NOTE: You can attach the Velcro on the opposite side of the blind if you want the blind to curve upwards. Some folks thinks that aids barrel cooling — it’s worth a try.

How to Remove and Re-Attach the Mirage Shield
Removal of your mirage shield is accomplished by simply removing the blind. You can un-install the Velcro by pulling off the strips and then gently removing any adhesive residue left behind using an appropriate solvent. (Simple cooking oil may do the job.) Caution: With fine, high-polish blued barrels, test any solvent on a non-visible section of the barrel. Before storing the gun, re-oil the barrel to remove active solvents and residual fingerprints.

Credit our buddy Joe Friedrich for this simple yet effective accessory for your benchrest rifle. Joe shoots a .22 LR benchrest rig with a barrel tuner. When he added weights to his tuner, he found his rifle no longer balanced well. He wanted to add some weight in the rear without drilling holes in the stock. He also wanted the weight to be removable, and easily placed on another rifle in his stable. He wanted a weight that could be moved from gun to gun as needed.

At a local sporting goods shop Joe found a 1.5-lb ankle weight that comes in a padded, tubular elastic cover. It’s like a 1.5-lb sausage in a soft, stretchy nylon cover. (Imagine a really fat, heavy bungee cord). Joe simply attached a plastic zip tie at the end to make a loop that fits perfectly over his buttstock. CLICK HERE for full-screen photo.

To “tune” the rifle’s balance, Joe just slides the ankle weight fore and aft on the stock. We have tried this moveable ankle weight on a variety of different BR stocks (including a McMillan Edge) and it worked perfectly. This is a great invention, and would work with sporter rifles and ARs just as well.

NOTE: Obviously, this ring will increase the measured weight of your rifle. So, if you are competing in a registered match with weight restrictions, you have to ensure that your rifle still makes class weight limits with the ankle weight ring in place.

Here is Ernie Bishop’s pride and joy, a specialty pistol nicknamed “Batman” because the black carbon-fiber stock looks like the Batmobile. This is one sophisticated handgun. Complete with scope, the Batman pistol weighs under 7.5 pounds, thanks to the ultra-light stock. The carbon stock is 6 inches wide at the fore-end, yet weighs just one pound. Ernie tells us: “This gun shoots amazing and is easy to shoot especially with my SEB MAX Rest.” After these photos were taken, Ernie added a “field-usable rear-grip stock so [he could] shoot it prone from a bipod as well.”

The Batman pistol is chambered for the 6mm “Long Dasher”, a 6mm 40°-shouldered variant of the 6.5×47 Lapua. Ernie loads Berger 105gr Hybrid bullets pushed by Hodgdon H4350 powder.

Gun Specifications
The gun, crafted by Eric Wallance of Nawaka Firearms, features an XP-100 action, Jewell trigger, and 15″-long, Brux 1:8″-twist barrel with aluminum muzzle brake. Interestingly, this gun does not have a traditional recoil lug. Instead, gunsmith Wallace milled out a lug from the bottom of the XP-100 action to save weight. On top of the action, the rig carries a Sightron Inc S-III 6-24X56mm scope in Kelbly rings on a custom +20 MOA rail.

Long Dasher Wildcat
Shown at right is a “Long Dasher” 40° wildcat created by Forum member Sunbuilder. This is very similar to Ernie Bishop’s chambering, though there may be small variations related to reamer design (such as freebore). Sunbuilder’s 6-6.5×47 Improved (aka “Long Dasher”) reamer was made by Dave Kiff of Pacific, Tool & Gauge. This wildcat cartridge adds about 2.0 grains capacity to the 6.5×47 necked down to 6mm. The case certainly is impressive with that 40° shoulder. We’re just waiting for the tactical guys to starting run this improved cartridge with its original 6.5mm bore.

Here are three FIVE-shot groups at 500 yards, shot by Ernie’s Batman pistol. The first 5-shot group is marked with pink dots, the second with green dots, and the third is measured with the calipers:

Here’s something of interest for benchrest competitors, particularly those who shoot at 100/200/300 yards. In those disciplines, high magnification is very important, and fixed-power options are popular. And in a game where the goal is to shoot in the ones and zeros, it is absolutely vital to have a scope that never experiences even the slightest shot-to-shot change (drift), and that allows very precise adjustments for windage and elevation. If you have a scope that moves internally, even the slightest amount, from one shot to the next, that can ruin a group.

Sightron offers a competition scope that should be a serious option for benchrest shooters. The Sightron SIII Competition 36x45mm ED riflescopes offer quality glass, precise adjustments, and reticles that hold steady — with no drift from shot to shot. This is a side-parallax scope with 1/10 MOA click values. Two Reticles are offered: Fine Crosshair (FCH), and FCH with 0.125 MOA Target Dot. This scope is in stock now at Creedmoor Sports for $1259.99, or direct from Sightron for the same $1259.99 price.

Sightron ExacTrack Windage and Elevation
When you’re trying to shoot one-hole groups, you need a scope that holds its values, and can also give precise, 100% repeatable adjustments when you need to dial a windage or elevation change. This SII ED’s ExacTrack windage and elevation adjustment system maintains proper alignment of the adjustments to the erector tube. That, Sightron says, ensures “precision and accuracy even when the most dramatic adjustments are applied.” NOTE: The adjustment values for both windage and elevation are 1/10th MOA. That is unusual. We usually see 1/8th MOA clicks in this type of scope. Here the click values are one-tenth Minute of Angle. (NOT 1/10 MIL). Sightron notes: “Precise target knobs with 1/10th MOA click value provide hair-splitting accuracy.”

ED (Extra Low-Dispersion) Glass in New 36x45mm Optic
The SIII Competition 36×45 ED features precision ED glass for crisp, razor-sharp views with minimal chromatic aberration — Sightron promises “crystal-clear target definition” with no color hazing. The SIII SS 36x45mm ED boasts Zact-7 Revcoat multi-coated precision ground lenses. Sightron claims “the highest quality light transmission in the industry”. A side parallax adjustment knob allows the riflescope to focus from 10 yards to infinity.

NOTE: If you want more magnification, Sightron also offers a 45x45mm SIII scope with ED Glass. To learn about that, READ Sightron 45x45mm SIII ED Review.

NOTE: All SIII Competition ED target riflescopes are compatible with all air guns and are backed by SIGHTRON’s lifetime limited warranty.

We created the above target a decade ago. Since then it has been used by tens of thousands of shooters. It has proven very popular as a load development target, since all your load data fits neatly in the boxes under each target. In fact this target is being employed by both rifle-makers and barrel-makers (including Criterion) to test their products. The target was designed for aiming efficiency. The diamonds have 1/2″ sides and you can align your cross-hairs on the horizontal and vertical lines. It is a clean design that is easy to see even at 200 yards with a 20X scope. When we test, we usually crank in a little elevation, setting the point-of-impact higher, so that our shots fall in the gray circles. That way you leave the squares intact for precise aiming.

Register for the Forum and you can add your favorite gun to the list.

We hope these “Pride and Joy” rifles may provide inspiration for our readers, whetting their appetite for their next competition, varminting, or hunting rifle project.

Ultra-Low Profile 6 PPC for Short-Range Benchrest

This handsome rifle, which belongs to Forum member J.J.Coe, represents the state-of-the-art for 100/200-yard benchrest rifles. It is chambered (no surprise) for the 6 PPC cartridge, which dominates the short-range game. In features a super-low profile carbon composite stock. Note how the vertical centerline of the stock is very close to the barrel. This keeps the center of gravity low and helps the rifle recoil smoothly with less hop in the bags. Note also the tuner on the barrel.

22 BR Savage Varminter — Accuracy on a Budget

This 22 BR Savage, with upgrades from Sharpshooter Supply, is the “pride and joy” of Forum member Maynard. Note the heavy-contour custom barrel with brake. That 22 BR cartridge is a very effective choice for varmint work, as the ground hog in the photo proves. The 22 BR and 22 Dasher are capable of outstanding accuracy with a large variety of bullets and powders. A 22 Dasher can rival the ballistics of a 6mmBR out to 500+ yards, but with reduced recoil.

Eliseo Tubegun in 7mm SAUM with Pierce Action, Bartlein Barrel

Here is a striking camo-finished Elesio (Competition Machine) Tubegun chambered for 7mm SAUM. Note the block fitted to the tubular fore-end so the rifle rides smooth and steady on the Rodzilla T-Rex joystick front rest. The proud owner, Forum member Aeon, tells us: “This is a Gary Eliseo RTM chassis with pickle forks. It has a custom Ceracoat paint job to match my sling gun.” Key components are: Pierce Engineering long action tube receiver, Bartlein 1:8.5″-twist barrel, Jewell trigger set at 2 oz., and Vortex Golden Eagle scope in Vortex rings. Aeon adds: “The chamber was cut by Mark Chesesbro of Chesebro Rifles. Mark throated it very long so the the 180gr and 184gr Bergers would sit where they belong.”

Tuning the 7mm SAUM and Recoil Reduction
Owner Aeon tells us: “The 7 SAUM was as easy a gun as I have ever shot to find a good load for — H1000 gave great consistency and tuning was not hard. However, the challenge in shooting this rifle was recoil management. The 7 SAUM has a punch to it and I found myself having trouble finishing three relays without form problems in the last relay. I considered getting a RAD Pad but that would have required expensive machine work. I stumbled on a recoil pad that is uniquely effective, the Falcon Strike. Sent the pad to Gary Eliseo and he sent it back with the butt plate machined to fit. Complete game changer! The rifle is a dream to shoot now with a big reduction in felt recoil.”

Ultra-Accurate 6.5×47 Lapua — Stiller Action, Bartlein Barrel

This gray and blue beauty belongs to Forum member Farmer Dave. He posted: “Got this 6.5×47 Lapua back from my smith about six months ago. It’s the most accurate rifle I have ever owned.” This rifle features: AG Composites CF stock, Stiller TAC 30 action, Bartlein 5R barrel, TriggerTech Diamond trigger. On top is a Trijicon Accupower riflescope.

Henry .45-70 with Modern Buttstock and M-LOK Handguard

Here is member Quest45’s handsome lever-action Henry .45-70 Gov and Glock 40 10mm. About his two guns he posted: “All I need is a can of bear spray”. The rifle is fitted with a red dot sight, ammo caddies, Ranger Point M-LOK handguard, and a modernized modular buttstock. These upgrades make it a thoroughly-modern Henry lever gun for the 21st Century.

A .243 Winchester Hunting Rig that Nailed Scottish Roe Buck

Forum member John V. from Scotland showcased a successful hunt with his .243 Winchester rifle. This sports a suppressed, 26″ MTU 1:7.5″-twist barrel. He loaded Sierra 100gr Pro-Hunter bullets, and took this nice Roe Buck at 240 yards through a gap in the foliage.

Mauser M96 with Quilted Maple Stock — for the Wife

We like this handsome quilted Maple-stocked Mauser belonging to Forum member Steel Mover. He posted: “Some like synthetic and some like wood — I have both. Here is the wife’s quilted Maple 96 Mauser 6.5×55. I was working in the shop, wife walked through and said ‘You are building that for me aren’t you?’ Well ‘Yes, dear’ I said of course … so I Lost my rifle.”

Patriotic .284 Shehane F-Open Rig

Forum member 1shot is proud of this new F-Classer: “Just got my first F-Open rifle finished chambered in .284 Shehane. It features a Kelbly stock w/RAD system, Shilen 1:8″-twist ratchet-rifled barrel with EC Tuner, and X-treme 2-stage trigger — all mated up to a Kelbly Panda action. I think this dog will hunt!”

Bill Goad’s 6PPC Hunter “Ranch Rifle”

Forum member Grimstod tells us: “This is the personal rifle of Bill Goad. He has been experimenting with it on several levels. It is shooting great and has several matches on it now. Please enjoy these photos. More can be found on the website www.PremierAccuracy.com. We like the subtle barbed wire effect on the stock.

Do-it-Yourself Paint Job, Done in the Bathroom at Home

Many eye-catching rifles start with a great paint job. Forum member JHN did this job himself. He posted: “Went to local paint shops, some cost a two-month work income, some said guns were a ‘no-no’. So I did it myself — my first Candy Apple red. Base collar is gold metallic, followed by the red. I didn’t have a good paintwork place so I had to improvise. Our bathroom has nice concealing in the summer — a perfect paint booth. So I only have to apologize about some red flakes in our bathroom.”

Here’s a simple solution for lumpy front sandbags. Cut a small block the width of your fore-end and place that in the front bag between matches. You can tap it down firmly with a rubber mallet.

The block will keep the front bag nice and square, without bunching up in the center. That will help your rifle track straight and true. Rick Beginski uses wood (see photo), while our friend John Southwick uses a small block of metal. The metal block might work a little better, but the wood version is easier to make with simple tools. Shown above is a slick Delrin block with a built-in bubble level used with a quality J.J. Loh front rest. Using a good block on your front bag helps ensure that the actual top surface of your front bag is level, as distinct from the front rest assembly.

For today’s Sunday GunDay story we showcase seven interesting metal-chassis rifles. While we love the look and feel of wood and fiberglass, metal does have its advantages. It can be crafted very straight and true, and the designs can achieve a very low center-of-gravity without sacrificing rigidity. In addition, a precisioned machined metal chassis tends to track extremely well.

Massive IBS Heavy Gun Milled from Solid Aluminum Billet

This remarkable 70-lb IBS Heavy Gun, was machined from solid aluminum billet, by Bruce Baer. It rests on a G&G Alvey rest split in the middle to comply with rules. This “heavy metal” CNC-machined wonder is a work of art designed for the 1000-yard game in the Heavy Gun class. Wood stocks, and to a lesser extent fiberglass stocks, are more forgiving, offering greater damping and recoil absorption. However, metal stocks offer superior rigidity, and the CNC machining allows tracking surfaces to be perfectly parallel.

Williamsport limits Heavy Guns to 100 pounds. Under IBS and NBRSA rules weight is unlimited. You will see a few massive 200-lb behemoths at IBS matches, but most competitors find that something in the 60-90 pound range works best. Bruce Baer explains, “You can’t stop a gun from recoiling. If it doesn’t recoil it will jump. If it jumps you might as well go home because you won’t shoot a good group. So it is pointless to try to build a gun so heavy as to eliminate all recoil. The more you restrict the rifle’s recoil the more temperamental that rifle will be. The 200-pounders just don’t out-perform something in the 60- to 80-pound range, and I think the optimal weight is 60-70 pounds.”

Bruce Baer likes the 70-lb overall weight for a heavy gun: “Extreme mass is not necessarily an advantage. Watch a locomotive starting up from zero–it will vibrate from one end to another. If the gun is too heavy I think it will vibrate at the start of recoil and that will kill accuracy. I want the gun to start from recoil with very little effort so it will be smooth from start to stop.”

Water-Cooled World Record-Setting Wondergun

We like “outside of the box” thinking. And in the world of competitive shooting, it can’t get more unconventional than this. But this radical liquid-cooled benchrest rig wasn’t just a crazy experiment — it actually delivered the goods. This IBS Heavy Gun, built by Joel Pendergraft, produced a superb 10-shot, 3.044″ group that stood as an International Benchrest Shooters (IBS) 1000-Yard Heavy Gun record for seven years, not being broken until 2016.

Using this water-cooled wondergun, Joel shot the record-breaking group in April 2009 at Hawks Ridge, NC. This monster features a .30-Caliber 12-twist, 4-groove Krieger barrel inside a water-filled sleeve (like on a liquid-cooled machine gun). Joel shot BIB 187gr flat-based bullets in Norma brass, pushed by a “generous amount” of Alliant Reloder 25 and Federal 210M primers. The cartridge was a big custom wildcat Joel listed as “.300 Ackley Improved”.

Pendergraft’s 3.044″ 10-shot group was a great feat, breaking one of the longest-standing, 1000-yard IBS World Records. And Joel’s 3.044″ record stood for 7 years!

F1 F-Open Chassis from Competition Machine

Along with his famed tube-guns, Gary Eliseo of Competition Machine has designed a modern, low-profile chassis system for F-Open competition. Assembled with Cerakoted aluminum beams, these F1 F-Open chassis systems offer great tracking with an ultra-low center of gravity.

Here is the F1 Chassis with “Marine Corps Red” powder coat finish. Read Full Report.

This F1 aluminum alloy chassis stock features a super-low center of gravity, plus adjustable length of pull, cheek rest, and drop. The stock is available in a wide choice of Cerakote finishes. The current Model F1 chassis features a action block mounting system to fit most actions. There was also an earlier version that had a free-floated action with the barrel in a barrel block, secured with epoxy. Both F1 versions (action block and barrel block) shot great, with excellent performances in competition.

Gen 1 F1 F-Open Chassis System with Barrel Block

State Championship Win with Home-Built Aluminum Stock

While most of the stocks featured above were crafted by professionals, the properties of aluminum allow it to be used by persons with some basic mechanical skills and metal-working tools. Here’s proof. Back in 2009, Forum Member John Dunbar (aka JD12) crafted his own aluminum F-Open stock. And he used that impressive metal stock to win the Wisconsin State F-Class championship. READ Full Story.

The stock for John’s “home-built” .284 Winchester was mated with a Savage target action. John designed and fabricated the aluminum stock himself. It features a central barrel block clamping a 32″ Brux barrel. Get this — John completed the rifle only 5 days before the match: “I finished machining/assembly on Monday night, did load workup Wednesday and Thursday nights, loaded rounds Friday night, and headed to Lodi at 4:30 on Saturday morning.” John even made his own co-axial front rest (see below)

Richard King’s Radical .223 Rem F-TR Skeleton Rifle

Here’s something exotic from our Gun of the Week archives. We like this rig because it is so radical (we doubt that you have ever seen anything quite like it). Gun-builder Richard King calls this his “Texas-T”, noting that “this is my personal gun, built the way I wanted it. I know it’s radical and some may not care for it. But it works.” The rig was designed to shoot F-TR, but it can also be converted easily to shoot F-Open with a front rest.

Richard reports: “This is pretty much an all-aluminum rifle. The action is a Kelbly F-Class with a Shilen stainless steel competition trigger. The scope is a 1″-tube Leupold 36X with a Tucker Conversion set in Jewell spherical bearing rings. The .223 barrel is 30″ Pac-Nor 3-groove, 1:6.5″-twist mounted in a V-type barrel block. The bipod has vertical adjustment only via a dovetail slide activated by a stick handle. It works like a joy-stick, but for vertical only. I adjust for windage by moving the rear sandbag.”

Richard likes how the barrel block works: “With the barrel block forward, the vibrations should be at a low frequency. Instead of one long rod whipping, I now have two short rods (barrel halves) being dampened. This is my fourth barrel block gun. They work, but so does a good pillar-bedded action. [This rifle] is designed for my style of shooting. It is not meant to be a universal ‘fit all’ for the general public. However, I will say the design is adaptable. I can easily convert the system to run in F-Open Class. I would drop a big-bore barreled action into the V-block, slide on a heavier pre-zeroed scope and rings, add plates on the sides up front to bring the width to 3″, and maybe a recoil pad.”

When Fiberglass Fails, Aluminum Stock Saves the Day

Australian Mark Fairbairn performed a “Quick Fix” during the 2018 Berger SW Nationals. Mark’s F-Open rifle, in a conventional fiberglass stock, was giving him random vertical during one yardage: “I had a bit of a problem with elevation — the stock was hitting somewhere [causing vertical]. I was X-X-X then a shot popped up in the 9 ring with no good reason. So I figured I better put a new stock on it. I got my old aluminium stock I brought from Australia and quickly adjusted it to fit on the Stolle.”

Right on the firing line berm Mark swapped his barreled action into the metal stock of his own design. The clock was ticking… but the story had a happy ending. For the next yardage Mark shot a brilliant 150-7X, not dropping a point. So the “Quick Fix” did the trick. As they say Down Under — “Good on Ya, Mate!”

Home-Built Aluminum Chassis with Innovative A-Arm Bipod

Here is another home-built rig featuring an aluminum chassis mated to a Savage barreled action via a forward-mounted barrel block. This rig was crafted by Forum member Patrick Lundy, who followed the maxim: “If you can’t buy it, then build it.”

Patrick Lundy was so impressed with a fellow shooter’s barrel-block rifle, that he build a similar match gun himself, complete with barrel block and aluminum chassis. Patrick was inspired by a metal stock belonging to Peter Gagne. But he added his own custom touches, including an innovative “A-Arm”-design bipod for shooting in F-TR class. The gun has been very successful in competition. READ FULL Report

Pat told us: “This new stock was a milestone in my shooting career — it was my very first attempt to build a stock. I wasn’t much of a wood worker but I did have a talent for building with metal. The stock was fabricated from 6061 T6 aluminum. With this gun I was able to shoot from a rest or a bipod.”

Pat crafted the bipod from aluminum tubing: “The bipod was a very rigid A-frame design with welded aluminum tubing. I added slippery feet under the pod skis to facilitate smoother recoil. I realized that a wide-stance bipod had to recoil the same on both sides or the group would string horizontally.” Here is the innovative “A-Arm” bipod that Pat Lundy built for his rifle.
