ABSTRACT:
A cartridge containing an environmentally friendly percussion primer employing a primer explosive mixture, packed under the paper disc and anvil; the mixture being a metastable interstitial composite (MIC) and a high explosive; and a second mass of high explosive, packed within the primer cup above the anvil—which mass of high explosive is ignited by the detonation of the MIC and high explosive mixture—thereby adding to the detonation to create a combined, enhanced pressure and temperature wave to more quickly initiate the booster pellet and propellant, to fire the bullet within the subject action time limit—even under extreme cold ambient conditions.
