Abstract
A method of making a colored projectile is disclosed, as well as the projectile made thereby. In an embodiment, the method comprises mechanically plating a colored metal, typically in powdered form, onto the surface of a projectile, such as a frangible, copper-based bullet, a full metal jacket bullet or a total metal jacket bullet. The disclosed plating process imparts a uniform, desired color to the surface of the plated projectile.
Claims20
A method of making a colored projectile, said method comprising:
- mechanically plating a metal onto the surface of the projectile, wherein said plating comprises:
- adding the projectile to a container comprising an aqueous slurry comprising at least one acid, at least one plating-assisting agent, and at least one particulate plating metal;
- rotating the container to agitate the projectile in said slurry for a time sufficient to plate the particulate plating metal on the surface of said projectile to form a plated projectile;
- rinsing the plated projectile;
- and
- treating the rinsed projectile with a composition comprising at least one chromium compound, water-soluble polymer and dyes to the surface of said projectile.

A method of making a colored frangible bullet, said method comprising:
- mechanically plating a metal onto the surface of a frangible metal bullet, the frangible
- metal bullet comprising a compacted mixture of copper powder comprising partially sintered
- particles that are physically bonded to each other to form a cohesive and ductile microstructure,
- wherein said plating comprises:
- adding the frangible metal bullet to a container comprising an aqueous slurry comprising at least one acid, at least one plating-assisting agent, and at least one particulate plating metal;
- rotating the container to agitate the frangible metal bullet in said slurry for a time sufficient to plate the particulate plating metal on the surface of said frangible metal bullet to form a plated frangible metal bullet;
- rinsing the plated frangible metal bullet;
- and
- treating the rinsed bullet with a composition comprising at least one chromium compound, water-soluble polymer and dyes to the surface of said plated frangible metal bullet.
