FIELD: ammunition, in particular, bullets for smoothbore sporting guns. SUBSTANCE: bullet uses a plastic wad-container- stabilizer, with turbine lugs made on its external lateral surface, inclined to one side. The rear end has an obturating skirt, near which on the lateral surface one more skirt is made, whose surfaces in longitudinal section represent curved lines in the form of ellipses. The diameter of the rear obturating skirt in the rear part exceeds the diameter of the cartridge case duct, and that of the front skirt is less then the diameter in the middle part of contraction between the cartridge chamber and cylindrical part of the barrel. The front end of the wad-container-stabilizer has a cavity, which accommodates the bullet body consisting of a cylindrical jacket with a seat in the front end, cylindrical in the rear part and expanding in the front part, the seat accommodates the mating slug end-piece, it has nicks to the depth of the seat; the length of the end-piece is less than the depth of the seat. Made in the end of the cavity of the wad-container-stabilizer is a cylindrical lug, which enters a similar cavity in the rear end of the body jacket and rests on a gasket made of elastic material. An annular groove contracting inside is made on the lateral surface of the body jacket, near the seat end, and lugs are made from the front end of the jacket, they are arranged in the mating grooves on the lateral surface of the cavity in the wad-container-stabilizer against the lugs of its turbine. The nicks in the front end of the body jacket are parallel to these lugs. EFFECT: reduced recoil, improved obturation, enhanced bullet velocity, enhanced accuracy and injurious effect. 3 dwg |
