FIELD: sporting gun ammunition, in particular, spin- stabilized bullets. SUBSTANCE: the novelty in the bullet is the fact that it is furnished with elements made of polymeric material with sections falling beyond the dimensions of the metal driving bands on their outside diameter, as well as the fact that the metal driving bands are made on their outside diameter smaller than the caliber of the smoothbore barrel forming a guaranteed clearance. EFFECT: enhanced bullet velocity, enhanced wear resistance of barrels in their smoothbore section. |
