Abstract: An ignition composition and its applications, the ignition composition including at least (a) an explosive fraction that includes at least one primary explosive, (b) an oxidation-reduction system and (c) an agglomerate. In the ignition composition the explosive fraction represents 9 to 35% by weight of the composition, the primary explosive at least is tetrazene, and tetrazene represents at least 95% by weight of said explosive fraction.

Abstract: The invention relates to a method for manufacturing cylinders (1) for cartridge cases, carried out in a rotary press machine, wherein a composition (2) of essentially plant origin is made available in a precise volume and weight, the cavities (3) of cylindrical molds (4) adapted to said cylinders (1) are fed with said composition (2), for each cylinder, said composition (2) is compressed in the cavity (3) between on the one hand, two, lower and coaxial, cylindrical dies namely a peripheral die (5), capable of sliding axially in the mold (4) and a central die (6) capable of sliding axially independently in the die (5) and on the other hand, an upper die (7), the distance between the dies (5) and (7) defining the height of the cylinder, and the cylinders obtained are ejected.

Abstract: Cartridge case (1), especially for a smooth bore gun, comprising three elements made of plastic, namely a tubular body (2) with an assembly end (2a) which tapers into the shape of a cone frustum, a base (3) which has a frustoconical bore (3a) with substantially the same vertex angle as the tapering end (2a) of the tubular body, to which it is matched in order to act as a housing, and a bottom piece (4) with a frustoconical external profile of substantially the same vertex angle as the tapering end (2a) of the tubular body, and as the bore (3a) of the base (3).
