CARTRIDGE WITH ARROW-LIKE BULLETS (MODIFICATIONS) Russian patent published in 2000 - IPC

FIELD: ammunition for smoothbore small arms. SUBSTANCE: arrow-like bullets are led in the bore not by the leading member (pan, container), but directly by the structure members of bullets proper, by "packing" them together, the outside maximum diameter of the assembly in the nose and tail sections makes up the arms bore diameter; the combustion chamber of the propellant charge is locked by means of a wad-obturator, which functions as a piston and is press-fitted in the rear section of the guide bush, which, in turn, is press- fitted and swaged by the cartridge case mouth on the external side. An assembly of arrow-like bullets is tightly inserted inside the guide bush and hermetically sealed by the bush tabs according to the number of lateral arrow-like bullets in the cartridge. Press-fitted in the multiple bullet cartridge with a tracer arrow-like bullet, in the tail section of the latter, is a magnesium tracer core, whose cone section, in turn, is rolled in the central hole of the wad-obturator and makes up a strong joint with it up to the burn-out of the core nose section. EFFECT: improved close grouping of shots. 17 dwg
