Abstract
A cartridge case with a case crush region that facilitates an additional amount of case crush in the axial direction, per unit of input force and energy, as compared to an identical cartridge case without such a region. The crush region may conceivably be either of a fully or partially circumferential nature with applicability to any style cartridge case, be it bottleneck or straight-walled and of any rim configuration (rimmed, semi-rimmed, rimless, rebated-rim, belted) and without prejudice to the case material (brass, stainless steel, polymer, etc.). This feature may be incorporated into the design of existing cartridge cases as well as future designs.
