CORROSION-INHIBITED PROJECTILES, AND SHOT SHELLS INCLUDING THE SAME

摘要

Corrosion-inhibited copper-containing projectiles and shot shells including the same. The projectiles include a core that is formed from a core material, and an outer coating that is formed from a coating material. The core material includes copper, and optionally may include at least 50 wt % copper. In some embodiments, the outer coating maintains a corrosion rate of copper within the core material below 0.00075 mmpy. The shot shells include a shot charge that includes a plurality of the projectiles.

主权项

1. A shot shell, comprising:
a cylindrical casing that defines a head portion, a mouth region, and an enclosed volume; a primer that is operatively attached to the head portion and defines a portion of the enclosed volume; a propellant charge that is located within the enclosed volume proximal to the primer, wherein the propellant charge is in thermal communication with the primer, and further wherein the primer is configured to selectively ignite the propellant charge; a shot charge that is located within the enclosed volume proximal to the mouth region, wherein the shot charge includes a plurality of projectiles that include: (i) a core that is formed from a core material, wherein the core material includes at least 50 wt % copper; and (ii) an outer coating that is formed from a coating material that is different from the core material and is selected to decrease a corrosion rate of the core material; and a wad that is located within the enclosed volume and separates the shot charge from the propellant charge.
