摘要： Shot projectiles are disclosed that are not completely spherical. The shot has an equatorial ring, top and bottom poles, and one or more sections extending between the ring and the respective poles. The ring defines a vertical height relative to an overall diameter of the projectile. The one or more sections provide flat, concave, or convex surfaces.

摘要： Frangible firearm projectiles, firearm cartridges containing the same, and methods for forming the same. The firearm projectiles are formed from compacted metal powders that may include an anti-sparking agent. The compacted metal powders may be or include a compacted mixture of metal powders that may include powders of one or more of iron, zinc, bismuth, copper, tungsten, nickel, boron, and/or alloys thereof, and/or oxides thereof. The compacted mixture may be heat treated for a time sufficient to form a plurality of discrete alloy domains within the compacted mixture. The frangible firearm projectile may be formed by a mechanism that includes vapor-phase diffusion bonding and oxidation of the metal powders and that does not include forming a liquid phase of any of the metal powders or utilizing a polymeric binder. The anti-sparking agent may include a borate, such as boric acid.

摘要： A cartridge with an expanding bullet that has advantageous terminal effects over an extended range. The expanding bullet including a bullet body including a metal jacket extending from a tail portion to a nose portion and surrounding an interior solid core and defining a forward opening and interior cavity. A tip has an exterior surface substantially flush with an exterior surface of the metal jacket. The tip has a main portion forward of the opening and a tip retention portion that at least partially fills the interior cavity. In certain embodiments the tip retention portion includes one or more fluid entry facilitation means such as a fracture regions configured to, upon impact of the bullet with a target, fracture or deform to expose one or more fluid pathways into the interior cavity and to a forward facing interior surface for initiating expansion of the expanding bullet.

摘要： In various embodiments, a projectile includes a projectile body including a tail portion, a nose portion, a barrel engaging portion between the nose portion and the tail portion, and a metal jacket that defines an exterior of the projectile that surrounds an interior solid core. In one or more embodiments the projectile includes one or more circumferential grooves defined in the interior core portion, each of the one or more circumferential grooves covered by and positioned adjacent to the metal jacket and within the barrel-engaging portion. In various embodiments, during firing of the projectile, the one or more circumferential grooves define a void that allows material of one or more of the metal jacket and interior solid core to displace into the void for reduction in radial stiffness to the projectile in the barrel engaging portion.

摘要： A system for firing reduced energy cartridges from a modern sporting rifle utilizes a bolt assembly weighing less than a conventional bolt assembly for such rifles and utilizes blow back for cycling the bolt assembly rather than gas operation. A bolt insert in a polymer bolt carrier of the bolt assembly has a projection that fits within a recess on the rear face of reduced energy cartridges. The reduced energy cartridges having a polymer casing, a rimfire power load for propellant, the power load recessed from the rear face of the casing. Tuning the bolt may comprise adjusting the weight of the bolt or the sliding resistance of the bolt assembly in the upper receiver. The bolt may be formed by metal injection molding with a polymer bolt carrier attached thereto.

摘要： A two piece, two-stage, reduced-energy mechanically operating cartridge is provided for launching, a configured bullet choice of various compositions from a dedicated or modified firearm. The cartridge unit is comprised of a primary case having a cavity to receive a propellant unit or propellant connection and a piston sleeve having a cavity to receive the configured bullet choice, the primary case coupled to the piston sleeve. The cartridge having a retracted pre-firing state and an expanded fired state whereby the piston sleeve and primary case telescope apart forcing, the firearm's slide or bolt to the rear, a mechanical operation opposed to a conventional cartridge with gas blow back operations.
