ABSTRACT:
A propellant igniter for a cartridge including an ignition tube which extends into the propellant; and with a booster charge arranged at one end of the ignition tube having a pyrotechnic igniting composition therein, which leaves the presence of a central passageway. The igniting composition or charge is formed from a tubular, hardened or set layer constituted of a pyrotechnic lacquer or varnish. Preferably, the pyrotechnic layer is cast into the ignition tube while in a pourable state, and then hardened or cured within the tube. The pyrotechnic layer can also be applied onto a combustible conduit tube for gas fumes, hardened thereon and then inserted into the ignition tube.
