US 2009/0151592 A1 · BULLET SHELL FOR SMOOTHBORE AND RIFLED CHOKE HUNTING GUNS

Abstract

Disclosed is a bullet shell for hunting guns, preferably those having barrels with “rifled choke” rifling. The shell comprises a bullet made of a solid material and a thin-wall plastic envelope. On its surface, the bullet has a trapezoidal groove delimiting nose and heel portions of the bullet. The envelope enclosing the bullet is made of identical longitudinal halves having a cylindrical outer surface and an inner surface matching with the surface of the bullet. A peripheral flat collar of a width of b and a height of b1=0.5b is provided at the bullet nose portion end surface. The collar passes into a taper boring with an apex angle α=120±5°, and the envelope protrudes by b2=b1 beyond the plane of the bullet collar. The bullet shell offers improved longitudinal stability when shooting through minor obstacles (bushes, grass) and improved grouping of up to 60 mm at 100 m.
