Patent ID: 8267015

Claim:
A projectile, comprising: a leading part including a tip having a generally ogive shape; a trailing part including a main base; a cylindrical interface including a leading end that abuttingly engages a trailing end of said tip and a trailing end that abuttingly engages a leading end of said main base; a non-round aperture having a predetermined longitudinal extent formed in said trailing end of said tip; a non-round peg having a predetermined longitudinal extent substantially equal to the predetermined longitudinal extent of said non-round aperture formed in said leading end of said main base; said non-round aperture and said non-round peg being centered on a longitudinal axis of symmetry of said projectile, said longitudinal axis of symmetry being a longitudinal axis of rotation of said projectile; and said non-round peg being slideably inserted within said non-round aperture when the leading end of said cylindrical interface abuts said trailing end of said tip and the trailing end of said cylindrical interface abuts said leading end of said main base so that said leading and trailing parts of said projectile rotate conjointly with one another when said projectile is rotating about said axis of rotation.
