Abstract
A lead-free projectile having a metal jacket (10) with a tip in the form of a truncated parabellum. The metal jacket (10) is partially filled with cold-pressed metal powder (18), the remainder of the metal jacket being filled with metal-filled polymer (26). The metal-filled polymer (26) extends through the truncated parabellum and forms a tip on the projectile. A projectile (bullet) having a higher grain is obtained. Methods of manufacture are also disclosed.

A lead-free projectile having a metal jacket with a tip in the form of a truncated parabellum, said metal jacket being partially filled with cold-pressed metal powder and being filled with metal-filled polymer, said metal-filled polymer extending through the truncated parabellum and forming a tip on said projectile.
A method of forming a lead-free projectile, comprising:
- (a) placing a pre-formed open ended metal jacket in a mould, said jacket being formable under pressure;
- (b) adding a pre-determined amount of metal powder into said jacket;
- (c) compacting said powder by cold pressing the powder in the jacket;
- (d) forming the open end of the jacket into a truncated parabellum;
- and
- (e) filling the jacket by injecting a metal-loaded polymer therein and forming a tip of said metal-loaded polymer on the projectile exterior to the truncated parabellum.
