Abstract
A lead free environmentally friendly ammunition which may be tailored within a range of compositions for specific uses, but generally comprises a mixture of metal powder and mineral filler in combination with a water soluble binder plastic resin and a lubricant. For hunting uses and other uses requiring high level accuracy the amount of metal powder is increased, for other uses where precision shooting is less important such as drug dosing of animals, less metal is used along with increased amounts of mineral filler. The bullets are accurate, and can be frangible. Formulations within the overall range may also be used to make shot for shotgun shells.
Claims15
A non-ricochet ammunition projectile composition comprising:
- from about 60% by weight to about 90% by weight of a composite powder combination of metal and mineral filler, said metal being selected from the group consisting of copper, tungsten, steel, bismuth, ferrotungsten, tantalum, zinc, antimony, and mixtures thereof, said mineral filler being a naturally occurring mineral, with the composite powder having a particle size of from 100 U.S. mesh to 325 U.S. mesh;
- from about 8% by weight to about 40% by weight of said ammunition composition being a water soluble thermoplastic resin binder;
- and
- from about 2% by weight to about 5% by weight of the ammunition composition being a fatty acid lubricant;
- said projectile having a density of from about 1.75 g/cc to about 8.25 g/cc and being a non-ricochet projectile when fired.
In a shell for a firearm having a primer, casing and bullet, the improvement comprising:
- from about 60% by weight to about 90% by weight of a composite powder combination of metal and mineral filler, said metal being selected from the group consisting of copper, tungsten, steel, bismuth, ferrotungsten, tantalum, zinc, antimony, and mixtures thereof, said mineral filler being a naturally occurring mineral, with the composite powder having a particle size of from 100 U.S. mesh to 325 U.S. mesh;
- from about 8% by weight to about 40% by weight of said ammunition composition being a water soluble thermoplastic resin binder;
- and
- from about 2% by weight to about 5% by weight of the ammunition composition being a fatty acid lubricant;
- said projectile having a density of from about 1.75 g/cc to about 8.25 g/cc and being a non-ricochet projectile when fired.
