ABSTRACT:
Aerodynamic cartridge and bullet combination in which the bullet is provided with a substantially smooth, edge-free contour, and a heel having rebated boat tail. An upright wall in the cartridge is attached to the boat tail by crimping. The cartridge houses a radially expandable wad which is arranged between the bullet and a propellant. The wad permits use of harder bullets than conventionally employed in ammunition by ensuring an effective gas seal between the propellant and bullet, and heel swage out or minimal heel deformation depending on wad configuration during burning of the propellant. Etches are provided in the bullet for receiving a long-chain polymeric lubricant coating which reduces leading in the rifle barrel.
