12.7mm Bullet Information

The 12.7mm bullet, also known as the .50 caliber bullet, is a large-caliber round primarily designed for long-range anti-materiel and anti-personnel use. Here's some key information:

• Design & Purpose: It's typically used in heavy machine guns and sniper rifles. Its primary role is to disable lightly armored vehicles, equipment, and fortifications. It can also be effective against personnel at long ranges.

  • Ball: Standard projectile for general purpose use.

  • Armor-Piercing (AP): Designed to penetrate armor plating.
  • Incendiary: Contains a flammable substance that ignites upon impact.
  • Armor-Piercing Incendiary (API): Combines the effects of armor-piercing and incendiary rounds.

• Weapons Platforms: Common weapons that use the 12.7mm round include the M2 Browning machine gun, the DShK heavy machine gun, and various sniper rifles like the Barrett M82.

• Stopping Power: Due to its size and high energy, the 12.7mm bullet delivers significant stopping power. It can inflict severe trauma on a target.
