Abstract: A billet adapted for use in a solid phase extrusion process to produce an extrudate, the billet including a billet body formed from Copper or Copper-Silver alloy, where the body defines a longitudinal void that extends along a longitudinal length of the body, powdered Graphene or powdered Carbon nano-tubes or nano-crystalline Carbon powder positioned in the longitudinal void and distributed evenly along the longitudinal length of the body, and where the weight percentage of the Carbon material relative to the metal in the body is between 10 ppm and 250 ppm, and where the billet is configured such that, after extrusion through the solid phase extrusion process to produce the extrudate, the extrudate has consistent conductivity is consistently greater than the conductivity of the Copper or Copper-Silver alloy.

Abstract: A method of producing a metal matrix composite by extruding a billet including both a metallic material and a non-metallic material through a die to form a metal matrix composite extrudate, where the non-metallic material is distributed evenly along a longitudinal length of the billet, where, during extrusion, a temperature of the billet does not exceed a melting temperature of the metallic material; and where the metal matrix composite extrudate has an extrusion ratio of at least 20:1.

Abstract: This application discloses a shaped charge firearm projectile that includes a two-piece jacket that defines an internal cavity with an opening in the front side of the jacket that is part of the internal cavity, a detonator positioned in the internal cavity, a striker passing through the opening with one end positioned outside of the internal cavity and the other end positioned near the detonator inside of the internal cavity positioned to detonate the detonator when the striker impacts a target with sufficient force, and a main charge positioned in the internal cavity with the main charge and the jacket defining an air-filled chamber located between the front side of the jacket and the main charge, where the striker extends into the main charge.
