  • Patent number: 9375772
    Abstract: A method to form a disposable compressed gas cartridge, wherein the method provides a steel sheet, and using sequentially (N) progressively longer dies forms from the steel sheet a vessel comprising a cylindrical wall, a closed end, and an open end, wherein the cylindrical wall comprises a body diameter, and wherein (N) is greater than equal to 5. The method then heats a first portion of the vessel at an annealing temperature, wherein that first portion includes the open end and a portion of the cylindrical wall adjacent the open end. The method then uses sequentially (M) tubular dies to form a cartridge neck by progressively narrowing the first portion of the vessel from the body diameter at a distal end of the first portion to an open end diameter at the open end to form an empty gas cartridge, wherein the body diameter is greater than a neck diameter.

  • Patent number: 9329009
    Abstract: The present invention in some aspects is directed to small arms ammunition and programmed upset characteristics thereof imparted to them using lasers. More particularly, the invention relates to ammunition and methods of making ammunition having predetermined patterns of engraving and/or cutting or hardening and/or annealing imparted into the forward portion using a programming laser system adapted for treating projectiles to effect predetermined and consistent upset configurations. Lasers may be used in forming steps of the bullet core to provide petaling or other performance objectives before or after jacketing or without jacketing.

  • Patent number: 9188415
    Abstract: A part of a cover is pressed radially into a circumferential groove contour in a projectile body by a preferably rigid die, which need only be moved axially and which is provided with a special outer contour. An outer contour should be matched to the groove contour or vice versa, so that the material of the cover that is formed radially by the forward-moving die can be pressed into the groove contour of the projectile body, and the cover no longer has any degrees of freedom after the forming, so that it is secured with respect to the tracer or the like. The cover is preferably a cover ring.

  • Patent number: 9134103
    Abstract: The current invention is directed to a cost effective method of manufacturing bullets or projectiles for use in firearms which are identifiable after firing and undergoing damage from striking targets. The mass production of large quantities of low cost ammunition makes adoption of a requirement that projectiles be so identifiable unlikely unless manufacturing methods and costs are not substantially disrupted. The method envisioned produces projectile bodies from rod or wire stock by parting slugs, piercing recesses, inserting tags and swaging a projectile body with a wholly or partially encased identification with indicia. The stock may be extruded around premade identification tags. The tags may have repeated indicia in each projectile and some indicia may be accessible from the outside of a completed round of ammunition. The swaging process retains the identification tags which are protected by the body of the projectile for recovery after the projectile is used.

    Abstract: A jacketed bullet and high-speed method of manufacturing jacketed bullets are provided. The method includes the steps of providing tubing and inserting a wire into the tubing to form composite tubular stock. The inner surface of the tubing is bonded to the outer surface of the inserted wire to form bonded tubular stock. After the bonding step, an inner diameter of the tubing is substantially equal to the wire diameter such that, when viewed in section, the wire completely fills the tubing. After the bonding step, the bonded tubular stock is cut to form work-pieces of a desired length. The workpieces are then warm or cold forged to form jacketed bullets.

    Abstract: A three component bullet with a core retention feature and a method of forming the bullet is described. The bullet can include a jacket surrounding a core and a locking band disposed around a circumference of the jacket and the core. The locking band can be received in a circumferential depression formed in the jacket and the core such as by compressing the core to cause the core and the jacket to expand radially fore and aft of the locking band. The circumferential depression can include shoulders that are in compressive engagement with the locking band to help secure the locking band in place. The circumferential depression can include an inwardly-extending annular band of jacket material which embeds itself into the core material with the result that the core is locked inside the jacket.

  • Patent number: 7013786
    Abstract: A shot pellet that, has an inner core of a material such tungsten carbide, that is coated with a layer of bismuth. This coating is molecularly bonded to the tungsten carbide and is not an alloy. The unique properties of the shot pellet allow its density to be tailored. Under this process, the effective density of the pellet can be made to be identical to lead for direct replacement in current lead loading formulations. Additionally, the density can be made to be lower than lead for shotguns requiring low barrel pressures, or higher than lead for enhanced energy transfer while maintaining the other advantages of the instant invention.

  • Patent number: 6935217
    Abstract: A frangible projectile for gun ammunition wherein the projectile includes a core 96 formed from one or more metal powders which are pressed into a self-supporting compact and incorporated into a metal jacket 10. The metal jacket is initially cup-shaped (generally cylindrical in overall geometry) with an open end 14 and a closed end 16. In accordance with one embodiment of the present invention the closed end of the jacket becomes the trailing end of the projectile. In another embodiment, the closed end of the jacket becomes the leading end of the projectile. In either embodiment, that surface 20 of the closed end 16 of the jacket which faces inwardly of the volume of the jacket is indented and stressed over substantially its entire area in accordance with a pattern of indentions 22 which enhances the frangibility of this closed end of the projectile when the projectile strikes a target.

  • Patent number: 6840149
    Abstract: A method of forming a gun ammunition projectile 52 including a leading end defined by an ogive 53 including the steps of admixing a quantity of a first powdered metal having a first melting point and a first density, with a quantity of a second powdered metal having a second, and lower, melting point and a second, and lesser, density, pressing a quantity of the admixed metal powders into a self-supporting compact having at least an outboard end disposing the compact in a cup-shaped jacket, heating the compact in the jacket, in a vertical attitude, to a temperature of at least the melting point of the second metal but less than the melting point of the first metal, for a time sufficient to result in a liquefied portion of the second metal migrating to and accumulating at the one outboard end of the compact.

  • Publication number: 20030192425
    Abstract: A method of manufacturing a soft point bullet and the bullet resulting there from. The method comprises forming a bullet core of a first material plated with a second material; providing a cavity in one end of the plated core of preferably polygonal shape and positioning a shaped blank of plating material into the cavity; and forming the core into the final bullet size and shape by extruding the core into the cavity to form the bullet nose and encapsulate the shaped blank within the bullet.
