Abstract
A blank cartridge and mated blank chamber for simulated firearms incapable of discharging projectiles. The blank cartridge has a case with a cartridge base, a case wall, a cartridge shoulder forming a neck, and a nose enclosing the blank cartridge. The blank cartridge nose provides more reliable feeding from magazines of simulated firearms. The blank cartridge dimensions render it inoperable with ammunition chambers of actual projectile-discharging firearms. The blank chamber dimensions render it inoperable with ammunition cartridges. Upon discharge the blank cartridge and chamber release exhaust gases in a forward direction, creating realistic visual and auditory effects.
