Abstract
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.
