ABSTRACT:
A cartridge has a case comprising a body housed telescopically within a sleeve. The body encloses a main chamber which contains gas under pressure, and a valve mechanism for venting gas from the chamber into an expansion chamber. The pressure of the gas in the expansion chamber causes the body to move rearwardly relative to the sleeve to apply a force to the breech block of the weapon in which the cartridge is used, thereby to initiate the reloading cycle. Gas is vented from the expansion chamber to eject a projectile when a spigot projecting from the body is withdrawn from an aperture in the end wall of the sleeve.
