Abstract
An IM type steel cartridge whose base contains a central bore there through—within which bore is a steel base plug holding a primer cup, the base plug being held in place by a low melt, 220 to 250 degree F. melt eutectic solder—wherein, if the cartridge is subjected to an unforeseen thermal or kinetic event, the solder will melt, the base plug ejected, and the propellant will vent rather than explode. The solder bond between the base plug and the cartridge case within which it is held is capable of resisting the from about 72,000, to up to 90,000 psi, force generated within the firing chamber of the weapon by the ignition and firing of the cartridge.
