Firearm projectiles and cartridges and methods of manufacturing the same
View Patent ↗Firearm projectiles and methods of manufacturing firearm projectiles from a supply of clad wire. In some embodiments, the clad wire is manufactured as electrical wire, such as copper-clad steel wire. Bullets and shot, as well as methods of forming bullets and shot, from clad wire are disclosed.
1. A method of forming ammunition shot from a length of clad wire, the clad wire including an inner core and a cladding surrounding the inner core, the method comprising:
obtaining a supply of copper-clad steel wire, wherein the copper-clad steel wire was manufactured as a standard gauge electrical wire;
performing at least one of:
working the copper-clad steel wire into a plurality of interconnected pellets, wherein each pellet has a dimension generally corresponding to a desired diameter of the ammunition shot, and separating the plurality of interconnected pellets into individual pellets;
cutting individual pellets from the supply of the copper-clad steel wire, wherein each pellet has a dimension generally corresponding to a desired diameter of the ammunition shot; and
pinching the clad wire to form individual pellets so that the cladding of the clad wire wraps around the metal from the inner core of the clad wire, and wherein the individual pellets substantially do not include exposed metal from the inner core of the clad wire; and
rounding the individual pellets into generally spherical pellets.
2. The method of claim 1 , wherein the desired diameter corresponds to a standard ammunition shot diameter.
3. The method of claim 1 , wherein prior to the performing, the method includes cutting the supply into lengths of copper-clad steel wire and straightening the lengths of copper-clad steel wire.
4. The method of claim 1 , wherein the rounding includes refining the plurality of pellets to make the plurality of pellets more spherical in shape than prior to the refining.
5. The method of claim 1 , wherein the method further includes passivating the cladding of the plurality of pellets.
6. The method of claim 1 , wherein the method further includes at least one of electroplating, painting, and plastic coating the plurality of pellets.
7. The method of claim 1 , wherein the method further includes loading a plurality of the ammunition shot into a shotgun cartridge.
8. Ammunition shot manufactured according to the method of claim 1 .
9. A shot shell comprising a plurality of ammunition shot according to claim 8 .
10. A method for forming clad ammunition shot, the method comprising:
forming ammunition shot from a length of clad wire, the clad wire including an inner core and a cladding surrounding the inner core, wherein the ammunition shot is configured to be received within a standard caliber shot shell, wherein the cladding is metallurgically bonded to the inner core and formed from a different composition than the inner core.
11. The method of claim 10 , wherein the clad wire is copper-clad steel wire.
12. The method of claim 10 , wherein the forming includes forming ammunition shot with a diameter that corresponds to a standard ammunition shot diameter.
13. The method of claim 10 , wherein the forming includes:
reducing a standard gauge clad wire from a standard diameter to a reduced diameter, wherein the reduced diameter corresponds at least approximately to a standard ammunition shot diameter.
14. The method of claim 10 , wherein the forming includes:
working the clad wire into a plurality of interconnected beads, wherein each bead has a dimension generally corresponding to a desired diameter of the ammunition shot;
and separating the plurality of interconnected beads into individual pellets.
15. The method of claim 10 , wherein the forming includes:
cutting individual pellets from the length of clad wire, wherein each pellet has a dimension generally corresponding to a desired diameter of the ammunition shot;
after the cutting, rounding the individual pellets into generally spherical pellets.
16. The method of claim 10 , wherein the forming includes pinching the clad wire to form individual pellets so that the cladding of the clad wire wraps around the metal from the inner core of the clad wire, and wherein the individual pellets substantially do not include exposed metal from the inner core of the clad wire.
17. The method of claim 16 , wherein the method further includes refining the pellets to make the pellets more spherical in shape than prior to the refining.
18. The method of claim 10 , wherein the method further includes passivating the ammunition shot.
19. The method of claim 10 , wherein the method further includes at least one of electroplating, painting, and plastic coating the ammunition shot.
20. The method of claim 10 , wherein the method further includes loading a plurality of the ammunition shot into a shotgun cartridge.
21. The method of claim 10 , further comprising:
prior to the forming, obtaining a supply of the clad wire from a third party, wherein the third party manufactures the clad wire as electrical wire.
22. The method of claim 10 , further comprising,
prior to the forming, manufacturing the clad wire.
23. Ammunition shot manufactured according to the method of claim 10 .
24. A shotgun cartridge comprising a plurality of ammunition shot according to claim 23 .
