Abstract:
1. An ammunition for a firearm comprising a cartridge case, supplementary ignition devices, a projectile, a primer case, and a propellant, wherein said supplementary ignition devices are placed inside the cartridge case immersed in the propellant, and have a ring-shaped structure so as to achieve an optimal incendiary action, resulting in a homogeneous and capillary detonation of the propellant, wherein each supplementary ignition device consists of a metal sheet structure, said structure comprising a rectangular hollow profile in the hollow space of which there is a mixture of igniting fulminate, wherein each supplementary ignition device has a flexible side such that, when subjected to a strong ambient pressure, it can assume a deformed position, wherein a strong ambient pressure is the normal pressure generated by the combustion of the propellant in the cartridge case, wherein the external wall of each ignition devices being integrally attached to the internal wall of the cartridge case, and each of the ignition devices comprising the plurality of strikers on the inner surface it's the flexible side and a plurality of flash holes in the metal sheet structure of each of the igniters for propagating the flame front/ignition outward from the ignition devices, and wherein on the inner surface of the side of the supplementary ignition device there is a plurality of fixed strikers.
