摘要： 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.

摘要： 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.
