  • Patent number: 7418904
    Abstract: The invention relates to an inert ballistic element and to a method for manufacturing it. Said method comprises the steps of: preparing a cylindrical tube, the ratio between the thickness and the outside diameter of said tube being equal or greater than 0.07; heating one end of the tube for a certain length until it is red hot; forging the end on a forging machine to form the tail and a part of the body of the ballistic element; heating the opposite end of the tube; and performing a second forging operation of the opposite part using a forging mould to form the nose of the ballistic element and to give the ballistic element its final shape. The forging operations are carried out with a forging machine equipped with a chuck that grips the tube by the non-heated end and pushes the tube into each nose or tail mould, which is divided into at least two shells that are moved by an opposite reciprocating motion.

  • Patent number: 7406906
    Abstract: Method and apparatus for the production of an ammunition projectile having enhanced properties relating to delivery of the projectile along its flight path from a weapon to, and upon striking, a target by reason of the formation of a meplat cavity in the leading end thereof which, from projectile to projectile, exhibits a uniform size, uniform geometry and which is free of extraneous material, and which is concentric with the centerline (spin axis) of the projectile. A round of ammunition is disclosed.

  • Publication number: 20080127850
    Abstract: An ammunition cartridge includes a tubular blank having a tail section in a shape of tail fins; a cap mated to a front section of the tubular blank; a solid core in a shape of a rod inside the tubular blank between the front and tail sections; and a casing having a propellant therein, the casing mated to the tubular blank. The core optionally includes an aerodynamic needle extending beyond the front portion. A portion of the aerodynamic needle inside the core is shaped as a spring. A muzzle wad and a washer are in contact with the muzzle wad and with the aerodynamic needle. The aerodynamic needle includes a portion embedded in the core that is shaped as a spring. The core includes a front portion and a rear portion, and a diameter of the front portion is larger than a diameter of the rear portion and is substantially equal to a diameter of the tubular blank. The cap can be conically shaped, round shaped, or can have a blunt front end, or can be shaped as two conical sections.

  • Patent number: 7322297
    Abstract: A method of canneluring a frangible projectile includes the steps of rotating the projectile at a high speed, and cutting the cannelure into the projectile to form a frangible cannelured projectile. To ensure that the body is not damaged during cutting, the cutting tool has bevels on each side of a square, generally flat, cutting surface. A frangible cannelured projectile made by the foregoing method includes a groove having a generally flat base and beveled edges.

  • Patent number: 7299750
    Abstract: Especially in hunting, the choice of bullets has to be such that it is in keeping with the wild animals to be hunted. According to the desired effect on the target, deformation bullets or partial fragmentation bullets are used. Since both types of bullets are different, the position of the point of impact from the same weapon is different. According to the type of bullet used, the weapon must be oriented differently in relation to the target. This can be obstructive and if insufficient attention is paid, can result in misses.

  • Patent number: 7059233
    Abstract: Tungsten-containing articles and manufacturing processes for tungsten-containing articles. The articles may include firearms projectiles, such as shot, shot slugs, bullets, big game bullets, lead-equivalent bullets, black powder bullets, etc.; radiation shields; and weights, such as fishing weights, dart weights, golf club weights, wheel weights, stabilizers, etc. The projectiles may be at least one of non-toxic, lead-free, ferromagnetic, frangible, sintered, sealed, plated, and/or jacketed. The manufacturing processes include various powder-metallurgy and molten metal processes, and sealing, reforming, intermediate structure, reshaping, plating, working, and jacketing steps which may be selectively utilized. The processes may include forming an intermediate structure and reshaping the structure under different pressure or process to a desired shape.

  • Patent number: 6938552
    Abstract: Structure incorporating lead is fabricated from specially prepared components such that mobility of the lead is impeded when the structure is exposed to an unprotected environment such as weathering outdoors or saltwater. In a preferred embodiment, a bullet or bullet core is swaged from a number of bunched electroplated fine lead or lead-alloy wires placed in a die. The lead or lead-alloy wires may be fabricated from lead or lead-alloy wool. The lead alloy may comprise zinc and antimony. The electroplating process plates zinc on the fine wires and may plate a zinc alloy such as zinc-aluminum. The plated surface may be coated with a corrosion resistant coating such as molybdenum phosphate. In addition to bullets and bullet cores, fishing weights, lead shielding, counterweights, ballast, and other lead containing structure may be fabricated or treated using methods and materials of the present invention.

  • Patent number: 6823798
    Abstract: Manufacturing processes for articles that are formed from compositions of matter that include powders containing tungsten and at least one binder, as well as articles formed thereby. In some embodiments, the processes include compacting the mixture of powders under a first pressure to yield a desired intermediate structure, then reshaping the structure under a second pressure that is lower than the first pressure to yield the desired article. The compacting steps may include punches and/or dies having different configurations and/or materials of construction. The composition of matter preferably is selected to reflow, or be reshaped, without fragmenting or otherwise disintegrating into discrete particles or particulate. In some embodiments, the compacted intermediate structure and/or final article has an extrusion constant of less than 30,000 psi. In some embodiments, the mixture of powders has an ASTM Hall flowmeter reading for fifty grams through a cone (without tapping) of less than 18 seconds.
