Abstract: The present invention pertains to fin-stabilized projectile ammunition, in which fin-stabilized projectiles are arranged in a cartridge case filled with propellant charge powder. According to the present invention, the spaces between the fins of the tail plane (4) of the fin-stabilized projectile (13) are filled with prefabricated shaped bodies (7) made from propellant charge powders. These shaped bodies in the ammunition are adjacent to the propellant charge powder in the cartridge case, and permit optimal utilization of the free space between the tail plane fins (20) of the projectiles being filled with high-energy propellant charge. Furthermore, the shaped bodies according to the present invention prevent corrosion of the tail plane fins during the burning off of the ammunition, and facilitate the manufacture of the ammunition.
