Jacketed Or Covered, Including Partially Patents (Class 86/55)
  • Patent number: 6629485
    Abstract: The method of making a non-lead hollow point bullet has the steps of a) compressing an unsintered powdered metal composite core into a jacket, b) punching a hollow cavity tip portion into the core, c) seating an insert, the insert having a hollow point tip and a tail protrusion, on top of the core such that the tail protrusion couples with the hollow cavity tip portion, and d) swaging the open tip of the jacket.

  • Patent number: 6591730
    Abstract: Method of manufacture of a multi-component projectile 14 for gun ammunition 16 including the steps of providing a uniformly spherical ball 18 of a ductile metal, either solid metal or a self-supporting pressed compact of metal powder particles, inserting the metal ball into the open end 10 of a cup-shaped jacket 54 which houses at least one core 30, the ball being disposed between that end of the core adjacent the open end of the jacket and the open end of the jacket. Axially directed pressure against the ball deforms the ball into a generally flat disc 36. Simultaneously, the core 30 may be seated within the closed end 26 of the jacket. Thereafter, the jacket/core/disc combination is die-formed to define an ogive 42 at the open end of the jacket.

  • Patent number: 6581503
    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.

  • Patent number: 6561070
    Abstract: A bullet, bullet jacket, and method of making the bullet and bullet jacket. The bullet jacket comprises a predominantly copper outer shell and a predominantly zinc lining. The bullet comprises the bullet jacket and a bullet core. The bullet jacket is made by forming a predominantly copper sheet and a predominantly zinc sheet. The two sheets are then adhered to one another by cladding or roll bonding, and shaped such that they can fully encase a bullet core. The bullet is then made by using conventional means to seat and enclose the bullet core within the bullet jacket of the present invention.

  • Publication number: 20020184995
    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, heating the compact, 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.

  • Patent number: 6371029
    Abstract: A disc for use in the manufacture of gun ammunition and a round of gun ammunition which includes the disc. A preferred disc comprises a mixture of metal powders compressed into self-supporting deformable disc that is incorporated along with a core into a jacket to define the projectile of a round of gun ammunition. The disc is frangible upon the projectile striking a solid or semi-solid target. Preferably the core is likewise frangible. In one embodiment the disc is incorporated into the ogive of a projectile. In another embodiment, a disc may be incorporated into a projectile comprising multiple cores, the disc being disposed between adjacent surfaces of the cores. This latter disc commonly is in addition to the disc which is incorporated into the ogive of the projectile. A round of gun ammunition incorporating a powder-based disc in the projectile thereof is disclosed.
