Abstract
A crush resistant cartridge case comprises a case shell having left and right halves. Each halve of the case shell contains a rigid insert having a flat portion with a rib extending substantially around the perimeter of the flat portion. The rigid inserts in the left and right halves of the case shell come together when the case shell is closed and provide resistance against crushing.
