Abstract

An improved expandable cartridge comprising a bushing made of deformable plastic material which is not flammable under normal firing conditions, characterized by a transverse wall formed integrally with the bushing to define an open ended projectile chamber at its mouth end and an open-ended propellant chamber at its breech end, the cartridge shell is of maximum diameter adjacent to the propulsion chamber and of a minimum diameter adjacent to the projectile chamber, a projectile at least partially placed in the chamber projectile and secured thereto, a propellant at least a portion of which is of a solid unitary construction placed in the propellant chamber so that the portion of the solid propeller closes the open end of the propellant chamber, a device of priming placed on and secured in the portion of the solid propellant, the propellant and the the priming device is made entirely of consumable materials so that when the propellant and the priming device are fired, they are almost completely consumed after which the plastic cartridge cap deforms and is forced out of the barrel of the weapon behind the projectile giving as a result that the entire cartridge is ejected from the weapon.
