They both fire the 50 BMG
The Barrett sniper rifle typically uses .50 caliber bullets.
The manufacturer is spelled Barrett (Barrett Firearms Manufacturing), builder of the M82 and XM500 .50 caliber sniper rifles that fire the 12.7x99mm NATO round (Browning machine gun round).
The .45 caliber bullet is not used in a sniper rifle.
The correct term is cartridge- which is the cartridge case, primer, powder, and bullet. A sniper rifle is simply an accurate, long range rifle that is used by a sniper. It may look exactly like my long range hunting rifle- since most military sniper rifles BEGAN as a civilian hunting weapon.
The first major deployment of the Barrett was in the first Gulf War.
Yes, I can. A Barrett M107 is a .50 caliber sniper rifle.
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.
Any bullet that has a diameter of one half inch is a .50 caliber bullet. There are different .50 caliber bullets- my Hawken muzzle loading rifle shoots a .50 caliber lead bullet, but different from the .50 Browning Machine Gun (that is also used in the .50 Barret sniper rifle)
