The present invention relates to a process for mechanically plating small arms projectiles with a particulate plating metal to form jacketed small arms projectiles. The process comprises agitating a slurry comprising the small arms projectiles, an aqueous solution of a strong acid, a plating agent and the particulate plating metal, thereby producing a jacketed small arms projectile having improved lubricity characteristics and in less time than prior art methods employing electrodeposition to form the jacketed small arms projectiles.

A process for mechanically plating small arms projectiles having a composition comprising a deformable metal selected from the group consisting of lead, an alloy of lead and an alloy of bismuth, with a coating of copper, said process comprising the steps of: (A) forming a slurry in an agitated container, said slurry comprising said small arms projectiles and an aqueous solution which contains components comprising a strong acid selected from the group consisting of fluoboric acid and methane sulfonic acid; (B) continuing to agitate said slurry until the surface of said small arms projectiles is essentially clean and free of oxide; (C) adding to the agitated container a plating agent and particulate copper metal; and (D) continuing to agitate the container until said particulate copper metal has been mechanically applied over the surface of said small arms projectiles. A small arms projectile mechanically plated according to claim 7.
