ball
The military overrun ammo on hand was 113-grain copper solid ball in 20-round boxes, 460-round cans, and 920-round crates. With a .330 ballistic coefficient and 3,200 FPS velocity out of a 16-inch barrel, these rounds spec out at 2,569 foot-pounds of energy at the muzzle. The case is a brass/stainless steel hybrid that allows for increased muzzle velocity/energy compared to traditional brass.
