An improved training cartridge has a plastic case skeletonized at its leading portion and defining a powder chamber at its trailing portion closed by an integral forward wall. The location of the wall is preselected to tailor the internal volume of the powder chamber to substantially equal that of the quantity of propellant charge employed by the cartridge so as to retain the charge in a fixed position in the chamber adjacent the primer. The configuration can either include a plastic bullet for training with projectiles having limited (reduced) range, or be made without a bullet, for those training exercises requiring blanks.
