Abstract
A projectile for use in a cartridge having a longitudinal axis, a leading end region, a trailing end region, and a chamber therebetween. The projectile is mounted in the leading end region and has a base. The base of the projectile is provided with one or more aerodynamically contoured features that receive forces generated by a propellant. The aerodynamically contoured features are concave or convex or are a combination of concave and convex so that some of the forces produce forwardly directed and rotational motion of the projectile.
