Abstract
A composite ammunition casing, especially for use in repeating firearms or guns in whose chambers a temperature gradient develops, from a maximum at the forward throat portion to a minimum at the rear breech portion. The casing includes a forward metallic member and a rear member formed of a material having a lower temperature resistance, such as plastic. The casing members have an interlocking junction at a point spaced along the firearm chamber at which the expected local temperature of the chamber drops to a level within the temperature resistance capability of the rear member. The interlocking junction is formed by surface interruptions in the wall of the forward member, into which the material of the rear member projects.
