Presented is a projectile (slug), which may be solid or hollow, encased in a sabot made of a semi-ridged material, usually plastic such as Teflon, with an arrangement to keep it in contact with the inner walls of a smooth bore weapon and automatically rotate, for stabilization, from the force of the expanding gases, while in the barrel, and wind pressure after this device exits the muzzle.
