Castable Frangible Projectile

A novel castable frangible projectile and techniques for manufacturing such are provided. A cartridge system includes a case defining a volume, a propellant disposed in the volume of the case, and a projectile coupled to the case. The projectile includes a body disposed at least partially within the case and configured to enclose the propellant within the volume of the case. The body is formed of a castable eutectic mixture, the castable eutectic mixture configured to be melted and cast, wherein the body is configured to break into a plurality of fragments upon impact with a target.

FRANGIBLE FIREARM PROJECTILES, METHODS FOR FORMING THE SAME, AND FIREARM CARTRIDGES CONTAINING THE SAME

Frangible firearm projectiles, firearm cartridges, and methods for forming the same. The projectiles are formed from metal powder and include an anti-sparking agent. One or more of iron, zinc, bismuth, tin, copper, nickel, tungsten, boron, and/or alloys thereof may form the metal powder. The projectiles may be formed from a compacted mixture of two or more different metal powders. The anti-sparking agent may include a borate, such as boric acid, zinc chloride, and/or petrolatum. The anti-sparking agent may be dispersed within, and/or applied as a coating on, the exterior of the projectile. The compacted mixture may be heat treated for a time sufficient to form a plurality of discrete alloy domains within the compacted mixture. Such domains may be formed by a mechanism that includes vapor-phase diffusion bonding and oxidation of the metal powders and that does form a liquid phase of the metal powder or utilize a polymeric binder.

Frangible firearm projectiles, methods for forming the same, and firearm cartridges containing the same

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.

Less-than-lethal kinetic impact round
11287230 · 2022-03-29 · ·

A less-than-lethal kinetic impact projectile and an associated less-than-lethal ammunition round are provided. The projectile has a typically self-supporting, sealed cylindrical elastomeric bag with a particulate load therein and with a deformable hemispherical hollow nose cap forwardly attached to a front of the cylindrical elastomeric bag. The round has a cylindrical casing with an ignitable propellant powder charge disposed therein, and the projectile nested within the casing forwardly of the propellant powder charge. In operation, the polymer material of the cylindrical elastomeric bag with deformable hollow nose cap is such that the projectile will expand in diameter but remain intact when impacting against a soft or semi-soft target (e.g., the body of a human being or animal), but will tend to fragment, disintegrate, or open up at the back, upon impact with a hard or semi hard target (e.g., against concrete or wood).
