An igniting system for a projectile propellant includes a combustible support tube having an outer surface and an inner surface; a plurality of throughgoing apertures provided in the support tube; a free igniting channel coaxially surrounded by the support tube; and an ignition transfer charge formed of a pyrotechnical hard foam layer having a thickness between 1 and 3 mm and being carried on the outer surface of the support tube. The hard foam layer is composed of a large-pore inner layer and two opposite surface layers which are of densely closed structure and between which the inner layer is sandwiched.
