A while back we published an Introduction to .50-Caliber Shooting authored by James Patterson. James has written a companion piece for Sinclair’s Reloading Press that covers the “care and feeding” of the big .50 Cal match rifles.
Owning and Feeding ‘The Big Bore’
Is The Challenge Of Big Bore Extreme Range Shooting And Hunting Right For You?
By James Patterson
Handling a 50 BMG
Is a 50 BMG caliber rifle difficult to shoot? Not at all. The relatively heavy weight of a standard rifle at 30 pounds or more combined with a very efficient muzzle brake makes it a pleasure to shoot. The typical recoil can be compared to a .243 rifle or a 12 gauge trap load. On the other hand, the burning of a typical load of 230 grains of powder combined with that muzzle brake makes the muzzle blast experience exhilarating. A first time shooter will fire, pause for a moment in awe at the muzzle blast, and then break out into what has become known as “The 50 caliber Grin”, almost impossible to wipe from ones face. My daughter started competing with the 50 BMG at 18 (115 lbs of tall skinny girl) and happily shoots 100+ rounds in the course of a match, her grin on the last round is as wide as on the first! Many members and competitors in the FCSA are women and many have distinguished themselves as excellent marksman having set world records on numerous occasions.
Cost of Big-Bore Shooting
Is owning and shooting a 50 BMG caliber rifle expensive? Relatively speaking yes, but one must put it into perspective. Rifles may run from $2500 to $7000, maybe even more for a top of the line custom rifle. A good scope will set you back $500 to $1500. And while excellent commercial ammo is available it runs from $3 to $5 a round. Most serious shooters start reloading for the rifle as soon as practical, not only for the economics of reloading but also for the ability to fine tune custom ammo for their specific rifle. It’s a very rare match that is won shooting commercial ammo. I recently compared the cost of my hobby — owning, shooting, and competing with the 50 BMG — with a friend whose hobby is snowmobiling. Factoring in the cost of equipment, licensing, gasoline, clothing, etc. it was soon obvious that my hobby was significantly less expensive than his.
Getting Started
 So how does one get started? You could do as I did, purchase a rifle not knowing what you were really getting into; or you could come out to a FCSA-sponsored event, shoot a number of different rifles, rub shoulders with those who have already taken the plunge, and see if this sport is right for you. While membership in the Fifty Caliber Shooters Association (FSCA) is required to compete at a FSCA event, membership is not required to come and experience first hand what is going on. If you have any inclination that you are interested in the extreme sport of long rang, big bore shooting then a year’s membership in the FCSA is only $60 ($20 for active duty military) a significant bargain if it helps you make just one well-informed equipment choice. In addition one of the primary functions of the FCSA is helping to identify active members near you who can help you understand just what is involved and help you ‘get your feet wet’ in this challenging sport.

Updating a 20+ Year-Old Benchrest Rifle
by James Mock
After owning three different rifles with BAT actions, I have become a loyal fan of BAT Machine quality and customer service. Back in 2009, I traded my BAT/Scoville for the BAT/Leonard that I currently shoot. This rifle has a long history and Terry Leonard told me that “Old 87″ (as I have named it) was one of the earlier BATs that he stocked. He wrapped the stock in fiberglass and used 2-part epoxy back then. I must say that this rifle has held up remarkably well since it dates back to the 1990s. The action is a RB/LP/RE octagon Model B with .308 bolt-face.
With this gun, I have shot several barrels of different calibers (.22 PPC, .22 PPC-short .095, 6mm PPC, 6XC, 6mm Dasher, .30BR, and will soon have a 6 BR-AI). It has been an exceptionally accurate rifle in several disciplines. In the hands of previous owners, it earned several Hall-of-Fame (HOF) points, and a “middle-of-the-pack” shooter (me) even received a HOF point with this rifle.
For most of its life, Old 87 served as a short range benchrest rifle, but I have used it for the last few years as a 600-yard rifle with the 6mm Dasher barrel. I was lucky enough to earn the Shooter of the Year award at the Prince Memorial Range in Louisiana for 2016.
After shooting my two Dasher barrels for last eight years, I have noticed a drop-off in accuracy at 600 yards. A decision had to be made — get a new barrel or sell the rifle and retire from competition. I will be 74 years old in six months and my competition days are limited due mainly to a chronic neck problem. After mulling over the decision to retire or not, I decided to give Old 87 one more year. Here is the story of how we upgraded the old war-horse.
Old 87 REBORN — Upgrading with New Components
I prefer cut-rifled barrels with four lands and grooves and have had success with .236 bore diameters and 1:8″ twist in long range rifles. I searched for barrels meeting those parameters and found a suitable BRUX at Bugholes.com (Southern Precision Rifles).
The 6BR-AI Option — Easy Fire Forming
I thought about having Billy Stevens chamber it for the Dasher, but decided to try something new. There seems to be a lot of interest in the 6BR-AI and I said, “Why not?” Well, I bought a shortened Dasher die from Harrell’s and will use my Wilson Dasher seating die. Bart Sauter was kind enough to let me use his reamer for chambering.
Fitting a New Roller-Type Cocking Piece on Older BAT Action
Since I was into the project this deep, I called Mike Ezell and ordered one of his Tungsten powder-dampened tuners. Since Old 87 had thousands of rounds since the firing pin spring has been replaced, I decided that it was probably needed. Well, I got to thinking (very dangerous) and asked Daryle Thom if it would be feasible to put a roller-type cocking piece and a new firing pin spring on such an old action.
The folks at BAT are very accommodating and they said that it would be no problem with such a conversion. While my bolt was in Idaho, the barrel with Ezell tuner arrived and I could not shoot it. However, my friend Jeff Turner loaned me his BAT bolt to see if it would work. Although the rifles differ in age by 15 or more years, the borrowed bolt worked perfectly in my rifle. This is a testimony to the great machine work performed at BAT Machine.
New Bolt Roller Tail-Piece Makes a Big Difference in Cocking Effort
With the borrowed bolt I managed to fire-form 50 rounds and get them ready for our 600-yard match on September 16. The folks at BAT quickly fixed my bolt by replacing the mainspring and ejector spring, polishing the ejector, and replacing the tail-piece with their roller type. Pictured below is this tail piece that makes a remarkable difference in the force needed to cock the action. It is amazing what this little wheel can do… even when placed in a 20+ year old action.
Working with the Ezell Barrel Tuner — Small Increments Work Best
Also, I would like to congratulate Mike Ezell on his new tuner which contains powdered Tungsten. It is easy to set up and Mike will help a buyer get maximum effectiveness from the unit. Just give him a call. Below is a picture of the tuner. I was lucky enough to have some time to “play” with it before the match.
Talking about the tuner, Mike writes: “Our new barrel tuners…
PDT stands for particle dampening technology. The science is there, we just applied it to a barrel tuner. The advantages are a wider tune window and more efficient control of barrel harmonics…in a tuner design that actually looks good.”
Mike advised me to set the tuner by turning it all the way into the shoulder and then come out to zero or the second time zero comes up if there is not at least half of a turn between the shoulder and the first zero. It is best to start with a proven load and adjust the tuner from that load. As unlikely as it seems, a rifle can go from a good tune to a very poor tune with only 5 marks (.005”) and vice versa.
Mike cautions those who use his tuner to NOT make adjustments which are too large. As a matter of fact, he recommends adjustments of .001 inch at a time. Ezell’s tuners are screwed onto the barrel with .900” by 32 threads per inch and has 32 marks on the circumference of the tuner. Therefore, each mark moves the tuner in or out by .001 inch. There are three set screws with Teflon tips which provide friction for the tuner on the threads. Do not tighten the screws so tight as they damage the fine threads.
If you want the smoothest bolt possible for your BAT, call or e-mail Daryle or Bruce Thom at BAT Machine and discuss your needs with them. I am sure glad that I did. If you want a state-of-the-Art tuner for your barrel, give Mike Ezell a call or visit his Ezell Custom Rifles Facebook Page.
— Good shooting, James Mock

A while back, RifleShooter online magazine published a list of the purported Ten Best Bolt-Action Rifles of All Time. Ten classic rifle designs (including the Remington 700 and Winchester Model 70) were featured with a paragraph or two explaining their notable features.
“Best” Lists Stir Controversy…
These Top 10 lists are always controversial. While most readers might approve of half the entries, there are always some items on the Top 10 list that some readers would challenge. Here is RifleShooter’s Top 10 list. What do you think? Are there some other bolt-actions that are more deserving?

A carpet is used up front for smoother tracking with the Joy-Pod’s flat, ski-style feet. The arms of the Joy-Pod were painted to match the stock. The rear bag features low-drag material on the ears.
The F-Class World Championships recently concluded in Canada. Our friend Derek Rodgers won the individual F-TR Championship using a rifle with a McMillan Xit stock and Kelbly F-Class Panda action. If you’re wondering what a modern F-TR competition rifle looks like, here is a new F-TR build from Forum member DM.Oakes.
Modern F-TR Rig with Borden Action, Krieger Barrel, and SEB Joy-Pod
This handsome .308 Win F-TR rig features a smooth-running Borden BRM action, 30-inch 1:10″-twist Krieger barrel, and an X-Ring Laminated Wood stock. Up front is a coaxial “Joy-Pod” joystick bipod. This is a state-of-the art, wide footprint bipod used by many competitors at the Worlds in Canada. The long joystick allows the “driver” to quickly adjust both elevation and windage in a smooth, continuous motion. The Joy-Pod can be adjusted so it will hold setting during the shot — you don’t have to “hard-hold” the joystick. Many shooters let the joystick slide through their fingers as the rifle moves back on recoil. With a little practice (and careful placement of the rear sand-bag), the tracking is excellent and you can slide the gun right back to point of aim after each shot.
Action: Borden BRM
Trigger: Blue-printed Jewell BR
Barrel: Krieger 30″ / 4-Grove / 1:10″ twist (.30 Cal)
Chamber: .308 Winchester with 0.170 Freebore
Stock: X-Ring Laminated F-Class
Scope: Nightforce 12-42x56mm Competition
Potential Name: Blue Thunder

Brian, a gunsmith at GA Precision, built this rimfire rig with GAP colleague Anthony Soukup.
On his Facebook page, Tactical competitor Bryan Sikes posted a photo of a rimfire rig we really liked. Brian works at GA Precision. He and fellow GAP gunsmith Anthony Soukup built this rifle. With a modified Rem 40X action, Manners stock, Bartlein barrel, and Mack Brothers suppressor, this rig has top-quality components stem to stern. And Bryan tells us this rifle performs as good as it looks: “This is the baddest little .22 LR trainer ever. I’m stoked about it. With the barrel length and can, it’s the exact length of my regular comp rigs.” With length, balance, and ergonomics near identical to Bryan’s centerfire competition rifles, this 40X is a superb training tool.
|
• Modified Remington 40X Action
• Calvin Elite Trigger
• Bartlein #5 22″ Barrel
• Mack Brothers Vapor Suppressor |
• Bedded Manners T4-A Stock
• Defiance Embedded Front Rail (EFR)
• Harris Swivel Bipod with Handle
• Bushnell DMR2 Scope w/ G3 Reticle |
Many readers wanted to know about the bottom metal and the detachable box magazine. Bryan Sike reveals: “The magazine setup is designed specifically to replicate my actual competition rifles. The bottom metal is for use with AI magazines and uses a standard M5 type inlet just like any centerfire completion rifle. In this case with the .22LR, Mike Bush designed a high reliability rimfire magazine using the same outside dimensions as an AI magazine. This rifle was built no different from any other. The action was modified and trued, barreled, fully bedded, etc. using ALL components common to centerfire match rifles.” The Rem 40X action was modified by Modacam Custom Rifles to work as a repeater with box mags.
Bryan adds that a new rimfire action is in the works: “My preference is modified Remington 40X actions and the soon-to-be available, V-22 action from Mike Bush. Both of which are TRUE repeaters and don’t feed from a Savage magazine. This rifle feels nothing like a .22 LR and that was the whole point.”
Why You Need a .22 LR Tactical Cross-Trainer
Many guys who shoot long-range tactical matches practice with .22 LR rifles of similar configuration. Rimfire ammo is way more affordable than centerfire, you do not need a big range facility, and shooting rimfire saves wear and tear on your centerfire rifle. Further, for learning how to read the wind, there really is no better training tool than a .22 LR, even as close as 50 yards.
Our Friend “DesertFrog”, who shoots tactical matches in Southern California, explains: “I used to shoot an average of 200 rounds of .308 Match ammo a month for training (50 per weekend). These days I shoot maybe an average of 50 rounds of .308 Win per month and probably around 600 rounds of .22 LR. Using mainly the .22 LR for practice did NOT hurt my standings in actual competitions. I shot my .308 just as well in matches, but saved the cost of hundreds of rounds of .308. If I didn’t reload and was still buying boxes of Federal Gold Medal Match .308 Win [at $1.00/round], this would be a savings of [$150 per month on the centerfire ammo.]” Money saved is money earned.

Wouldn’t it be great if you could have one match rifle that could do double-duty — shoot position matches (with sling), and then function as an F-Open gun with front rest? Now that’s possible with Gary Eliseo’s clever “PickleFork” accessory for his line of tubeguns. This accessory also works great for load testing and varmint hunting.
Competition Machine’s Gary Eliseo is a very smart designer as well as a talented shooter. The inventor/builder of the popular Competition Machine Tubegun chassis systems, Gary has come up with something new, which he calls the PickleForks. These are rails that fit to the sides of the tubular fore-end/handguard on his chassis systems. This allows you to use a pedestal-style front rest for F-Class competition. It also provides a much more stable platform for load testing, varmint hunting, or any kind of rest-assisted precision shooting.
These PickleForks transform a Tubegun into an ultra-stable, straight-tracking rig when used with a competition-style front rest.
Gary explains: “Now you can have the same super low-boreline, long ‘wheelbase’ and vertical sides of our innovative F1 F-Class chassis system for your tube chassis. The new PickleForks attach directly to the sides of the F-Class/Tactical fore-ends, no modifications are required. They are very rigid with no flex or twist and make the rifle track like it’s on rails.” The new Eliseo Competition Machine PickleForks are offered for a very reasonable $70.00 per pair, with Cerakote finish. (You get two metal units, one for each side of the fore-arm). For more information, visit www.GotXRing.com or call (928) 649-0742.

Ruger has issued a Product Safety Bulletin for certain Ruger Precision Rifles due to the potential for interference between the aluminum bolt shroud and the cocking piece (also known as the firing pin back). This can lead to light primer strikes. The real problem is that: “If the rifle fails to fire when the trigger is pulled, it may fire when the bolt handle is subsequently lifted”. NOTE: Ruger Precision Rifles with polymer bolt shrouds are NOT affected.
Although only a small percentage of rifles appear to be affected and there are no reported injuries, Ruger is offering replacement aluminum bolt shrouds for affected rifles in order to eliminate the possibility of bolt/shroud interference. View Safety Bulletin PDF
AFFECTED RIFLES: Ruger Precision Rifles (regardless of caliber) that have an aluminum bolt shroud and fall within the following serial number ranges are potentially affected:
SN 1800-26274 to 1800-78345 OR SN 1801-00506 to 1801-30461
If you believe your rifle is affected or are unsure if your rifle is affected, you can request a FREE replacement bolt shroud by visiting Ruger.com/RPRSafety.
DESCRIPTION OF ISSUE
Some Ruger Precision Rifles may experience interference between the aluminum bolt shroud and the cocking piece (aka the firing pin back). In rare instances, the interference can disrupt the firing mechanism and cause it to not function properly. Possible results of this interference are light primer strikes or, in extreme cases, the rifle may not fire when the trigger is pulled. If the rifle fails to fire when the trigger is pulled, it may fire when the bolt handle is subsequently lifted. In rifles where this condition exists, the issue often resolves itself as parts wear and interference is reduced.

Here’s an extreme range of .224-Caliber bullets: 35gr varmint bullet and 90gr match bullet. Of course, along with bullet length/design, you need to consider MV when choosing twist rate.
Even with the same caliber (and same bullet weight), different bullet types may require different rates of spin to stabilize properly. The bullet’s initial spin rate (RPM) is a function of the bullet’s muzzle velocity and the spin imparted by the rifling in the barrel. You want to ensure your bullet is stable throughout flight. It is better to have too much spin than too little, according to many ballistics experts, including Bryan Litz of Applied Ballistics. Glen Zediker has some basic tips concerning barrel twist rates and bullet stability. These come from his latest book, Top Grade Ammo.
Choosing the Right Twist Rate
I’d always rather have a twist too fast than not fast enough. Generally… I recommend erring toward the faster side of a barrel twist decision. 1:8″ twist is becoming a “new standard” for .224 caliber, replacing 1:9″ in the process. The reason is that new bullets tend to be bigger rather than smaller. Don’t let a too-slow twist limit your capacity to [achieve] better long-range performance.
Base your next barrel twist rate decision on the longest, heaviest bullets you choose to use, and at the same time realize that the rate you choose will in turn limit your bullet choices. If the longest, heaviest bullet you’ll shoot (ever) is a 55-grain .224, then there’s honestly no reason not to use a 1:12″. Likewise true for .308-caliber: unless you’re going over 200-grain bullet weight, a 1:10″ will perform perfectly well.
Bullet Length is More Critical than Weight
Bullet length, not weight, [primarily] determines how much rotation is necessary for stability. Twist rate suggestions, though, are most usually given with respect to bullet weight, but that’s more of a generality for convenience’s sake, I think. The reason is that with the introduction of higher-ballistic-coefficient bullet designs, which are longer than conventional forms, it is easily possible to have two same-weight bullets that won’t both stabilize from the same twist rate.
Evidence of Instability
The tell-tale for an unstable (wobbling or tumbling) bullet is an oblong hole in the target paper, a “keyhole,” and that means the bullet contacted the target at some attitude other than nose-first.
 Increasing Barrel Length Can Deliver More Velocity, But That May Still Not Provide Enough Stability if the Twist Rate Is Too Slow
Bullet speed and barrel length have an influence on bullet stability, and a higher muzzle velocity through a longer tube will bring on more effect from the twist, but it’s a little too edgy if a particular bullet stabilizes only when running maximum velocity.
My failed 90-grain .224 experiment is a good example of that: I could get them asleep in a 1:7″ twist, 25-inch barrel, which was chambered in .22 PPC, but could not get them stabilized in a 20-inch 1:7″ .223 Rem. The answer always is to get a twist that’s correct.
These tips were adapted from Glen’s newest book, Top-Grade Ammo, available at Midsouth. To learn more about this book and other Zediker titles, and read a host of downloadable articles, visit ZedikerPublishing.com.
