Abstract
A lightweight projectile having an integrated metal band positioned around the exterior of the polymer base of the projectile. The metal band may be a driving band that protrudes from the polymer base to minimize the contact between the polymer base and the rifling to reduce friction between the barrel and the projectile as the projectile is fired. The lightweight projectile may be propelled with less propellant force than conventional projectiles of the same caliber while still retaining the ballistic advantages of a spin stabilized projectile.
