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.

A method for manufacturing an enamel-coated bullet is described. The method starts with casting a bullet from a metal material and quenching the cast bullet. After the bullet cools, applying a lubricant to the bullet and sizing the bullet to the appropriate caliber and rinsing the bullets in a solvent. Thereafter, applying an enamel coating to the bullets. The coating uses about 1 part by volume lacquer thinner, about 1.5 parts by volume hardener, and about 2.5 parts by volume epoxy paint. The process continues by contacting the bullets with a moving fluid for a sufficient time that they become dry and heating the bullets in an oven at a temperature of between 150 and 250° F. for a time between 20 and 45 minutes. Finally, the process involves applying a lubricant to the coated bullet and resizing the bullet to the appropriate caliber.
