Abstract
A propellant charge igniter is provided with a metallic igniter tube which is consumed along with the main propellant charge. The combustible igniter tube is flexibly attached to a conventional primer head. An elastomeric tube, a springreinforced tube, or a tube impregnated with a wire mesh can be used to achieve a flexible connection. These tubular elements may be bonded to the primer head and igniter tube, or mechanically attached by means of threaded couplings which are crimped over the elastomeric tubing.
