US12379194 - Polymer jacketed powder core projectile

A method is disclosed for coating a projectile for use in an ammunition cartridge. A polymer jacket is applied to an undersized projectile core of a first standard caliber to bring the outer dimensions of the jacketed projectile into compliance with those of a second, larger caliber projectile. The polymer jacket coating may produce a non-uniform outer diameter of the polymer jacketed projectile and may include a plurality of circular cavities defined therein. The polymer-jacketed projectile may be a bullet for pistol or rifle ammunition, or a pellet, or shot for use in a shotgun shell.

This patent describes a polymer jacketed projectile that utilizes an undersized core to meet the dimensions of a larger caliber while maintaining a non-standard weight. The projectile can be used in various types of ammunition, including bullets for pistols and rifles, as well as pellets or shot for shotguns.

Claim 1

  1. A polymer jacketed projectile, comprising: an undersized core having a first diameter and a first length, wherein the first diameter is equal to a standard diameter for a first caliber projectile and wherein the first length is equal to a standard length for the first caliber projectile; a jacket covering an outer surface of the undersized core and made from polymer, wherein the jacket forms a second outer diameter and a second outer length, wherein the second outer diameter is equal to a standard diameter for a second caliber projectile and wherein the second outer length is equal to a standard length for the second caliber projectile; and wherein the polymer jacketed projectile has a weight unequal to a standard weight of the second caliber projectile. an undersized core having a first diameter and a first length, wherein the first diameter is equal to a standard diameter for a first caliber projectile and wherein the first length is equal to a standard length for the first caliber projectile; a jacket covering an outer surface of the undersized core and made from polymer, wherein the jacket forms a second outer diameter and a second outer length, wherein the second outer diameter is equal to a standard diameter for a second caliber projectile and wherein the second outer length is equal to a standard length for the second caliber projectile; and wherein the polymer jacketed projectile has a weight unequal to a standard weight of the second caliber projectile.
