Title: High power and practice shells - for hand and automatic weapons
Inventor: KOSCHE HORST H DIPL CHEM DR
IPC: F42B12/34
Filed: 1974-03-23
Abstract: In a high power and safety shell with controllable and limitable expansion, partic. for self-loading hand weapons small arms or automatic weapons or for sporting purposes, the shell contains an axially arranged expansion cone thickened toward the shell base and anchored in the shell tail, the shell head being mounted on this cone by compressive or injection action on the intermediately supported expansion part, so as to be displaceable towards the tail. In partic. the tail of the shell and the casing surrounding the expansion part consists of a workpiece of the same material contg. a bore into which the expansion is pressed or is forced in during firing. The shell can be assembled easily from cheap components which are so arranged and constructed that they have an expansion in the central zone in high power shells with retention of the material, but enlargement of the cross section in safety shells with impact type injection of the material.
