At the Berger SW Nationals this week many of the nation’s top sling shooters will be competing in the Palma (full-bore) class. You’ll see a scores of .308 Win Palma rifles on the firing line in Phoenix. However, we doubt any of those Ben Avery rigs will be more eye-catching than this Barnard-actioned beauty in an stunning Turkish Walnut stock…
In our Shooters’ Forum, there’s a long-running thread entitled Pride & Joy Rifles. There you’ll find dozens of fine firearms — from hunting handguns to long-range benchrest rigs. A while back, Forum member John L. (GunDog64) posted this handsome Palma rifle, built by Chad Dixon.
John reports: “Here is my new ‘Pride and Joy’ Palma rifle. The action is a chrome-moly Barnard supplied by MT Guns. The gun is set up for switch-barrel use with two Medium Palma-contour Bartlein barrels, one chambered in 6CM, the other in .308 Winchester. Both barrels feature 5R rifling. Up front is a Riles 30mm front sight, while the rear sight is a Warner. The stock was crafted from a superb Turkish walnut blank supplied by Luxus Gunstocks in Mt. Orab, Ohio.
Gunsmithing by Chad Dixon — Stock Finish by Owner
All gunsmithing and assembly work was performed by Chad Dixon at Long Rifles Inc., Sturgis, South Dakota. Chad designed the trigger guard, handstop rail, recoil lug, and cheek-piece adjuster. John, the rifle’s proud new owner, completed the finish work on the stock. John reveals: “This project was a year in the making but well worth the wait”.

Alliant’s Powder for 50-Caliber Applications
In 2009 Alliant unveiled Reloder 50, a new powder designed for long-range, 50-caliber rifle shooters. According to Alliant, the burn rate is “a little slower than Winchester 860″ and the powder is showing excellent lot-to-lot consistency. Load density is optimized for the 50 BMG and similar cases. Like Reloder 17, Reloder 50 employs a process which penetrates the kernels with the burn-rate-controlling chemical. This should allow a longer, flatter pressure curve, yielding more velocity than conventional powders can deliver. Alliant says that Reloder 50 offers “superior velocity and the ability to burn cleaner (with less residue).” Reloder 50 comes in both 1-lb (#150527) and 8-lb (#150528) containers.
Giraud 50 BMG Case/Bullet Comparator Giraud Tool makes a comparator for 50-Cal cartridges. The double-ended comparator is quite versatile. In one orientation you can measure base-to-ogive bullet length and also measure cartridge OAL from rim to bullet ogive. When reversed, you can use the comparator to measure cartridge headspace. The $30.00 Giraud 50 BMG Comparator gauge is constructed of 303 stainless and fits most any vernier, dial, or digital caliper. CLICK HERE for more info.
Forster 50 BMG Trimmer
50 BMG enthusiasts asked for a dedicated 50 BMG case trimmer, so Forster created a trimmer specifically for that cartridge. Forster’s cutter tip is much sharper than the cutter on the Lyman 50 Cal. AccuTrimmer. However, with the Forster tool you will pay more for that superior cutting ability — Forster’s 50 BMG trimmer costs $95.99 at Sinclair International. Yes, Lyman also makes a dedicated 50 BMG Case trimmer ($66.49 at MidwayUSA), but the Forster cutter head is much sharper, and we prefer the Forsters collet-style case-holder. Bottom line — the Forster gets the job done more quickly, with less effort, so it’s worth the extra money.
