.50 BMG (Browning Machine Gun) ammunition is a type of large-caliber rifle ammunition originally designed for use in the Browning M2 machine gun. It is now also used in a variety of other firearms, including rifles, sniper rifles, and anti-materiel rifles.
The .50 BMG cartridge is a centerfire cartridge that measures 12.7x99mm in size.

The bullet design for .50 BMG ammunition can vary, but typically features a lead core surrounded by a copper or brass jacket. The bullet may be a full metal jacket (FMJ), armor-piercing incendiary (API), or tracer, depending on the intended use. Armor-piercing and incendiary rounds are used for penetrating armor and disabling or destroying vehicles or structures, while tracer rounds are used for target identification.
.50 BMG ammunition is loaded with a consistent powder charge and primer, ensuring reliable performance and consistent accuracy. The cartridges are typically brass-cased and boxer-primed, which makes them easy to reload.
Overall, .50 BMG ammunition is a high-powered, highly effective ammunition that offers excellent accuracy and long-range capabilities. Its large, heavy bullet and high energy transfer make it an ideal choice for long-range shooting and anti-materiel applications, while its consistent performance and reliability make it a popular choice among military, law enforcement, and civilian users alike.
