A device and method for producing a secondary malfunction of a cartridge extracted from a firearm. A cartridge case has a bullet disposed in a front end and a rim formed at a rear end. The rim is tapered toward a primer, wherein the primer is disposed in the center of the rim. The tapered rim prevents a firearm from successfully extracting the cartridge case, i.e. a secondary malfunction occurs.
