ABSTRACT:
A training cartridge includes a metallic cartridge case with a case shoulder and dummy projectile having a gas exhaust opening at its front end. A propellant charge powder chamber of the cartridge case is closed in the forward direction by means of a cup-shaped closure element that is inserted in the cartridge case close to the case shoulder and that bursts or ruptures during firing under the action of the powder gases along predetermined intentional breaking zones. Toward the rear, the powder chamber is sealed by means of a bottom piece inserted in the cartridge case. By placing the intentional opening zones into the interior of the cartridge, danger of injury by the ejected cartridge case is reduced to a minimum.
