Firearm cartridge having a plurality of ignition primer chambers and associated methods for reducing the likelihood of misfire and cold shot and enhancing rapid and reliable firing

摘要

A multi-ignition cartridge and associated methods for use with a firearm are provided. The cartridge preferably includes a casing having an interior cavity which at least partially encloses at least one projectile. Chances of misfire and cold fire are substantially reduced by including in the casing a plurality of chambers. Each of the chambers preferably is in fluid communication with the cavity and containing an ignitable substance to ignite a main charge in the casing to propel the projectile from the casing. The ignitable substance in a chamber is ignited by striking a strike plate that can be positioned in contact with the casing. Related methods are provided for propelling the projectile of a firearm by simultaneously increasing pressure in multiple chambers of a cartridge casing so as to ignite in at least one chamber the ignitable substance contained in each so as to ignite a main charge that propels the projectile.
