Abstract
A cartridge with a drive system and a projectile which is connected to the drive system, wherein the drive system has a propellant case filled with a propellant and has a case bottom containing a substantially axially extending case bottom opening with a T-shaped edge contour. The case bottom opening is closed by a plug which is of T-shaped configuration, receives an ignition cap and is held in position by a safety fuse ring of a rupture disc. The safety fuse ring is arranged between the front side of the head part of the plug and the rear side of an adjoining inner-side projection of the case bottom, with the result that the propellant chamber is delimited by the front surface of the plug neck. An inner edge of the safety fuse ring engages in a positively locking and/or non-positive manner into an outer groove-shaped recess of the plug.
