About the .50 BMG Cartridge

The .50 Browning Machine Gun (.50 BMG, aka 12.7×99mm NATO or 50 Browning) is a cartridge developed for the Browning .50 caliber machine gun in the late 1910s, entering official service in 1921. Under STANAG 4383, it is a standard cartridge for NATO forces as well as many non-NATO countries.

John Browning had the idea for this round during World War I in response to a need for an anti-aircraft weapon, based on a scaled-up .30-06 Springfield design, used in a machine gun based on a scaled-up M1919/M1917 design that Browning had initially developed around 1900. According to the American Rifleman: “The Browning .50 originated in the Great War. American interest in an armor-piercing cartridge was influenced by the marginal French 11 mm design, prompting U.S. Army Ordnance officers to consult Browning. They wanted a heavy projectile at 2700 FPS, but the ammunition did not exist. Browning pondered the situation and, according to his son John, replied, ‘Well, the cartridge sounds pretty good to start. You make up some cartridges and we’ll do some shooting’.”

Reloading Powder and Special Tools for .50 BMG

Alliant 50 BMG PowderAlliant’s Powder for 50-Caliber Applications
In 2009 Alliant unveiled Reloder 50, a slow-burn-rate powder designed primarily 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.

Forster and Lyman .50 BMG Trimmers
Big Fifty enthusiasts asked for a dedicated .50 BMG case trimmer, so Forster and Lyman created .50 Cal trimmers specifically for that cartridge. Forster’s cutter tip on its .50 BMG Case Trimmer 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 — the Forster .50 BMG trimmer is $95.53 at Midsouth compared to $75.09 at Midsouth for the Lyman .50 BMG trimmer. Go head and pay the extra money for the Forster — the cutter head is much sharper, and we prefer the Forster’s collet-style case-holder. Bottom line — the Forster gets the job done more quickly, with less effort.

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 $33.00 Giraud .50 BMG Comparator gauge is constructed of 303 stainless and fits most any vernier, dial, or digital caliper. CLICK HERE for more info.

Wilkinson Wins Hunter Class at .50 Cal World Championships

Walter WilkinsonUsing a “box-stock”, 30-lb Steyr HS.50 rifle, Walter Wilkinson of Edgewood, NM, bested a field of 31 competitors (most using heavier custom rifles) to take the Hunter Class Score title at the recent Fifty Caliber Shooters Association World Championships. This event was held July 1st and 2nd at the NRA Whittington Center outside Raton, NM. This is the second year in a row that a competitor with an off-the-shelf Steyr HS.50 won the Hunter Class title. (Eduardo Abril de Fontcuberta won Hunter Class with an HS.50 last year.)

Wilkinson, a retired U.S. Army Special Forces sergeant major and current Gunsite Academy instructor, ran up a two-day Aggregate score of 274-6X out of a possible 300, beating his next closest competitor, .50 Cal legend Lee Rasmussen, by two Xs. The Hunter Class is a 1,000-yard course of fire consisting of six, five-shot strings, with three strings shot on the first day, and three strings shot on the second day. Due to the wildly varying winds on this range, competitors who shot in the morning of the first day were required to shoot in the afternoon of the second day, and vice versa, to equal the playing field.

Slotted in the first afternoon’s fourth relay, Wilkinson’s consistency, solid wind-doping and holding skills paid off as the winds made an especially tricky display with a 180-degree shift as thunderheads came over the Sangre de Cristo Mountains. Heading into his morning relay on the second day, Wilkinson found himself in second place with nothing to do but hammer the 10-ring to work his way into the championship title.

Wilkinson’s .50 Delivered Quarter-MOA Groups During Load Testing
Wilkinson said the Steyr .50-Cal has shown outstanding accuracy: “As I was working up a load for the HS.50, I shot groups that amazed me. I was getting groups of .214 MOA at 220 yards, and I didn’t know what to think. All the bullets were going in the same hole, and it was like ‘Wow, I’ve really got a rifle that can shoot here’. They were the best groups that I have ever shot in my life — and they were with the .50 BMG!” That surprised Wilkinson: “With my [military] experience with the performance of the same cartridge overseas, I didn’t expect that kind of accuracy out of it.”

Wilkinson Was Also Member of Winning .50 Cal Team
Along with his individual Hunter Class Title, Wilkinson earned team honors as a Ten-X team member. The Ten-X team won the Team World Championship with an aggregate score of 1081-24X combined with an average group size of 14.549 inches. Each team had four shooters with one from each of the four classes represented at the .50 Caliber Championships: Light, Heavy, Unlimited, and Hunter.
