Abstract

A cartridge that generates higher than typical chamber pressures has an enhanced means of primer retention for retaining the primer in the primer recess of the casing. The means may be a lip folded onto a conical surface, a annular groove to receive deformed primer wall portion material upon detonation, a concavity in the rearward facing wall of the primer, a check valve in the flash tube to inhibit propellant gases from reaching the primer recess, or specifically configured primers with a greater length than diameter and with greater wall thicknesses.
