摘要: A high pressure cartridge case is provided for firearms with blowback operating systems. The cartridge case is provided with a primer support member that supports a primer in a rearward end of a cartridge case. The support member is slideable rearwardly in the cartridge case when the cartridge is fired. The components expand to seal with the cartridge case to prevent the escape of gas around the support member when the propellant is ignited.
