Abstract

A casing bottom or stub casing for a propelling charge casing whose base plate (1) has an exterior or outer surface which is curved inwardly in an annular region (7) so that the casing bottom is able to sufficiently axially expand under the high gas pressure developing during firing without requiring the use of a high strength material.
