摘要:
Ammunition comprising a lead bullet having a coating comprised of polymeric material, e.g. a polyamide which may include a solid lubricant such as molybdenum disulfide Nylon 11 per se and other coatings are disclosed. The coating minimizes or prevents deposition of lead along the barrel and other mechanisms of a firearm. In the preferred method of manufacture, the bullet is degreased, roughened and heated to clean its surfaces. A phosphate coating is applied and the bullet is heated to a temperature of at least 425°F. The heated bullet is then disposed in blended molybdenum disulfide and Nylon 11 powder, Nylon 11 per se, or other coating materials to obtain a coating thickness within a range of 1 to 12 mils. The coated bullet is subsequently heated to at least 367°F to fuse and to densify the coating on the bullet.
