The .50 Browning Machine Gun (.50 BMG, 12.7×99mm NATO and designated as the 50 Browning by the C.I.P.) 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. The cartridge itself has been made in many variants: multiple generations of regular ball, tracer, armor-piercing (AP), incendiary, and saboted sub-caliber rounds. The rounds intended for machine guns are made into a continuous belt using metallic links.

The .50 BMG cartridge is also used in long-range target and anti-materiel rifles, as well as other .50-caliber machine guns.

A wide variety of ammunition is available, and the availability of match grade ammunition has increased the usefulness of .50 caliber rifles by allowing more accurate fire than lower quality rounds.

Dial in sharp carbide or HSS tools, crank speeds to 2,000–3,000 RPM, and take feather-light cuts (0.005–0.015 inches) to dodge melting or gummy buildup. Wet-sand from 220 to 2,000 grit, zap pin-holes with thin CA glue, and crown it with Magic Juice polish for that mirror-finish glow. Dive deeper with our guides:
