  • Method of making a bullet comprising a compacted mixture of copper powder
    Patent number: 11015908
    Abstract: A bullet comprising a compacted mixture of copper powder comprising particles that are physically bonded to each other to form a cohesive and ductile microstructure is disclosed. Methods of making such a bullet through powdered metallurgy techniques, which provide sufficient properties to allow the bullet to be loaded into a cartridge and crimped without fracture are also disclosed. Such bullets have sufficient strength to maintain their integrity during firing but may fragment upon impact and can be formulated lead-free.
    Type: Grant
    Filed: April 25, 2019
    Date of Patent: May 25, 2021
    Inventors: Michael Sloff, Brian Benini, Kevin Geist
  • Method of making a colored projectile
    Patent number: 10830565
    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.
