Abstract
Sabots for modern firearms, including both rifles and pistols, which have reduced friction thus imparting greater sub-caliber projectile velocity are made from a thermoplastic resin containing finely divided solid lubricant fillers. Preferably the forward end of the sabot is tapered to further reduce friction and improve cartridge feeding in automatic firearms.

A unitary one piece plastic sabot for projection through a rifled gun barrel which sabot is constructed from a nylon resin having dispersed particles of a solid lubricant throughout, said sabot consisting of a cylindrical sleeve having a back imperforate closed end and an open forward end defining a cylindrical projectile cavity said sleeve tapering gradually inwardly from a predetermined point on said sleeve to the forward end thereof and containing a plurality of equidistantly radially spaced slots extending axially from said open forward end a predetermined distance, said distance being less than the length of the cavity and at least as great as the lengths of the tapered portion of the sleeve.
