ABSTRACT:
A training cartridge has a synthetic resin projectile or dummy projectile wherein the projectile or dummy projectile is integrally molded to a synthetic resin sleeve or tube open at the rear end. The sleeve is inserted from the front end of a cartridge case of metal that is open at its front end. The sleeve is held within the cartridge case by drawing the cartridge case inwards, after insertion of the synthetic resin sleeve, in its frontal zone to form a conical case shoulder and a cylindrical case neck, which shoulder and neck encompass the synthetic resin sleeve in firm contact therewith. This arrangement achieves clean separation of the projectile from the remainder of the synthetic resin sleeve and/or avoids uncontrolled tearing off of parts of the synthetic resin sleeve.
