Abstract

An ammunition case including an elongate interior cavity for receiving a propellant and a projectile and extending along a longitudinal axis between a top end and a bottom end, and a bottom corner of the cavity having a reversed or broad radius design supported by a shaped base. In another aspect, an ammunition case may include a case, the case having a wall deformed in a pattern of deformations directed inwardly, enabling a balance of outer profile maintenance for general loading and handling while giving spring characteristics in an axial direction.
