Abstract
A cartridge case for centerfire ammunition may include a rotationally shaped casing sleeve for receiving a projectile as well as propellant charge powder, and a separate rotationally shaped bottom piece which is attached to the casing sleeve and has a closed ignition surface to be faced towards a firing pin for ignition of the centerfire ammunition. The closed ignition surface delimits, on the firing pin side, a receiving chamber for an ignition charge. The casing sleeve may have or support an anvil extending in the direction of the ignition surface into the receiving chamber. The ammunition may have a caliber in the range from, for example, 4.6 to 12.7.
