ABSTRACT:
A projectile includes a leading part formed by a tip and a tip base that form a first annular shoulder where they meet. A trailing part of the projectile is formed by a base having a frusto-conical trailing end and a cylindrical leading end of truncate extent that forms a tail drive. A second annular shoulder is formed where a cylindrical rod meets the tail drive. A flat trailing end of the tip base and a flat leading end of the cylindrical rod abut one another when the projectile is assembled. A cylindrical interface has a leading extent abutting the first annular shoulder and a trailing end abutting the second annular shoulder. The tail drive and the trailing extent of the cylindrical interface are the only parts of the projectile that engage gun barrel rifling when the projectile is positioned in a gun barrel.
