Abstract

A training cartridge has a plastic projectile or plastic dummy projectile wherein the projectile or dummy projectile is integrally molded on a synthetic resin sleeve open at the rear end. The sleeve is inserted in a cartridge case of metal open at its front end. The cartridge case with case shoulder and case neck formed thereon is made to be open also at the rear end so that the synthetic resin sleeve can be inserted from the rear end into the cartridge case in close contact with the inner wall thereof. A separate metallic bottom piece is inserted into the rear end of the cartridge case, sealing the case tightly toward the rear.
