BULLET FOR SMOOTHBORE HUNTING WEAPON Russian patent published in 2023 - IPC F42B7/10 F42B12/34 F42B30/02 

FIELD: weapons.

SUBSTANCE: invention relates to ammunition for smoothbore hunting weapon, namely to bullets. A bullet contains a case with a twisted element made of metal, for example, of spring steel. The bullet is additionally equipped with ballast and guiding sleeves with longitudinal grooves, an aerodynamic needle installed with the possibility of movement relatively to the longitudinal axis of the case, a cylindrical spring, a twisted element made of steel wire or a cord with a loop, with straight and spiral sections. The twisted element is connected to the guiding sleeve and a ratchet. The case is made with a cavity equipped with three or more protrusions radially located on an inner wall of its tail part, on which the ratchet, the aerodynamic needle, and the spring rest.

EFFECT: trajectory flatness, range, and accuracy of shots are improved, high aerodynamic parameters are provided, as well as a stopping effect of a bullet with the possibility of control of the specified bullet characteristics due to change in a position of its center of mass relatively to the center of pressure, sizes of a destruction channel, as well as reliable release from a bullet case of an additional striking part, namely a twisted element, only after hitting a target.
