Abstract : Ignition current is conducted by a firing circuit through a firing pin to a primer mixture retained by its cap within a cartridge case from which the cap is electrically separated by an insulator to effect primer ignition with reduced lock time by activation of a firing switch independently of the firing pin. Voltage for the firing circuit is derived from a battery, maintained in a charged condition by alternate voltage supply sources, and stored at an ignition firing level for a prolonged period of time to accommodate selective activation of the firing switch after the firing pin contacts the primer cap.
