The M82 has a .50 caliber bullet. The .50BMG round used in the M82 and the M107 is also known as the 12.7x99. The 99mm stands for the case length and the bullet protrudes a couple more inches out making the round about 5.5 inches in total. This round is not the most powerful round in the world as commonly thought with rounds that are 12.7x108 in the rifles such as the Gepard M-1, 14.5x114 in the Gepard M-3 and 30x173 and 30x113 in armored vehicles and in the A-10 thunderbolt. Also in the Bofors AA-Gun there is a 40x311round. In reality the 12.7x99 does not cut people in two as shown in movies.
The M82 was made in 2 calibers. The original used the .50 BMG cartridge, which fires a bullet that is .510 inches in diameter. The weight of the bullet varies depending on WHICH bullet is used, but is in the area of 700 grains weight. The later version of the M82 was made in caliber .416 Barrett. This is, as the name suggests, a .416 inch bullet that weighs 400 grains.
