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.
Claims (22)
1. 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,the remainder of the metal jacket being filled with metal-filled polymer, said metal-filled polymer extending through the truncated parabellum and forming a tip on said projectile.
2. The lead-free projectile of Claim 1 in which the projectile is a bullet.
3. The lead-free projectile of Claim 1 in which the jacket is a copper jacket.
4. The lead-free projectile of Claim 1 in which the metal powder is copper or tungsten.
5. The lead-free projectile of Claim 1 in which the metal-filled polymer is an amorphous or low crystallinity polymer filled with particles of copper, tungsten, bismuth, tin and/or stainless steel.
6. The lead-free projectile of Claim 5 in which the polymer is selected from the group consisting of ethylene/methacrylic acid copolymer ionomer, polyetherester elastomers and polyamide.
7. 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.
(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.
8. The method of Claim 7 in which the projectile is a bullet.
9. The method of Claim 7 in which the jacket is a copper jacket.
10.The method of Claim 7 in which the metal powder is copper or tungsten.
11. The method of Claim 7 in which the metal-filled polymer is an amorphous or low crystallinity polymer filled with particles of copper, tungsten, bismuth, tin and/or stainless steel.
12. The method of Claim 13 in which the polymer is selected from the group consisting of ethylene/methacrylic acid copolymer ionomer, polyetherester elastomers or polyamide.
13. 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) partially filling the jacket by injecting a metal-loaded polymer therein;
(c) adding metal powder into said jacket;
(d) compacting said powder by cold pressing the powder in the jacket; and (e) closing the open end of the jacket.
(a) placing a pre-formed open ended metal jacket in a mould,said jacket being formable under pressure;
(b) partially filling the jacket by injecting a metal-loaded polymer therein;
(c) adding metal powder into said jacket;
(d) compacting said powder by cold pressing the powder in the jacket; and (e) closing the open end of the jacket.
14. The method of Claim 13 in which the jacket has a pre-formed truncated parabellum, and a tip of said metal-loaded polymer is formed on the projectile in step (b).
15. The method of Claim 13 in which the projectile is a bullet.
16. The method of Claim 13 in which the jacket is a copper jacket.
17. The method of Claim 13 in which the metal powder is copper or tungsten.
18. The method of Claim 13 in which the metal-filled polymer is an amorphous or low crystallinity polymer filled with particles of copper,tungsten, bismuth, tin and/or stainless steel.
19. The method of Claim 18 in which the polymer is selected from the group consisting of ethylene/methacrylic acid copolymer ionomer, polyetherester elastomers or polyamide,
20. A lead free projectile comprising a preformed metal jacket having an open end and a closed tip end, said metal jacket being filled with cold-pressed powder and said open end being sealed with a metal filled polymer.
21. The projectile of claim 20 wherein the open end of said jacket curves inward to retain the polymer over the powder.
22. A method of forming a lead-free projectile, comprising:
a) providing a pre-formed metal jacket, having an open end and a closed tip end;
b) adding a predetermined amount of metal powder into the jacket through the open end;
c) compacting said powder by cold-pressing the powder in the jacket;
and d) filling the jacket with a metal-loaded polymer thereby closing the open end.
