ABSTRACT:
A combustible bayonet type primer for combustible cannon cartridge cases comprises a primer head assembly adapted to be inserted in a cartridge case, a tubular housing made of a combustible material, an igniter strand axially disposed in said housing, and a confining means for confining one end of the igniter strand so that the initial ignition rate is about 1000 m/s. The ignited strand in turn ignites a black powder charge contained within a cloth bag within the tubular housing. The housing is an unpressurized container for the igniter strand and the black powder charge and is consumed during the burn of the propellant bed along with the igniter strand and the combustible case.
