FIELD: ammunition.
SUBSTANCE: the round has a shell resting on the piston pusher made with a blind space limiting from the top the powder propellant charge, composite cartridge case with a screwed off flange and an initiating device. The powder propellant charge is placed in the screwed off flange of the cartridge case through the cartridge bag of the congruent shape of the flange inner surface. The tubular pusher is geometrically closed by centering shoulders made on the end faces of the piston and shell. Grooves are made on the surface of the contact of the piston and cartridge case. The screwed off flange is connected to the cartridge case through the obturating ring.
EFFECT: enhanced reliability and trouble-free-functioning of an easier and efficient cartridge at a concealed fire.
