Abstract

A cartridge case made of plastics or paraffinised paper, and containing a powdered charge and made to exclude moisture, consists of a tube (10) with a plug forced into each end, one plug (12) carrying an elongated closed detonator tube extending rearwards. The remainder of this plug is identical is the other plug (11). Each plug is hollow, with the inner chamfered end followed by a parallel portion carrying three semicircular section rings around it. The outside diameter of the rings exceeds the inside diameter of the tube by at least 0.3 mm, and they cover at least half the length of the plug. The length of the plug is at least half the inside diameter of the tube.
