Abstract

Sporting cartridge has a part of extruded pipe with injected head which has a base piece with a conical inner extension of corresp. length. Internally, in the middle of the base piece is a frustroconical thickening or reinforcement which lies concentric with an opening that seats a detonator. Preferably the opening has 3 regions of different dia., the outer of small axial length to receive the edge of the detonator, the middle with a large axial length and small dia. to receive the body of the detonator, and the inner forming a step or shoulder under the detonator, preventing passage of explosion gases through the gap between the base and detonator in conjunction with the press. below the gap by action of the explosion itself on the frustroconical surface.
