A chamber and blank cartridge of specific dimensions for safer use in simulated firearms. The dimensions of the chamber make it incompatible for use with known lethal cartridges. The dimensions of the blank cartridge make it incompatible with the chambers of actual firearms. This prevents the inadvertent loading of lethal or blank cartridges. Upon discharge the blank cartridge and chamber release exhaust gases in a forward direction. This effect is similar to an actual firearm and so generates realistic visual and auditory effects. The blank cartridge has a nose which may increase propellant capacity. The use of additional propellant will generate greater energy for visual and auditory effects. This will also improves the cycling of actions of larger simulated automatic firearms. The shape of the nose also improves magazine feeding in automatic simulated firearms.
