Publication number: 20150033973Abstract: The current invention is directed to a cost effective method of manufacturing bullets or projectiles for firearms which are identifiable after firing and undergoing damage. The mass production 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 encasing identification tag material, and swaging a projectile body with a wholly or partially encased tag with indicia. The stock may be extruded around premade identification tags or a recess may be reverse extruded in each slug. 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.Type: ApplicationFiled: October 8, 2014Publication date: February 5, 2015Inventor: Thomas Danaher Harvey

Patent number: 7665402Abstract: A method of manufacturing ammunition 10 for firing from the barrel of a weapon comprises forming a mould 32 having an interior surface, placing a core 42 in the mould 32 to produce a casting void 43 and pouring a liquefied solidifiable material into the casting void 43. Upon solidification of the material, the core 42 is removed to produce a projectile body 12 having a closed end and an opposite end. The removal of the core 42 also creates the cavity 18 in the projectile body 12 that opens onto the opposite end. The projectile body 12 is removed from the mould 32 and a quantity of propellant 22 is deposited into the cavity 18 through the opposite end. A seal 26 which incorporates a primer is pressed into the opposite end. Circumferential flanges 30a and 30b are integrally moulded with the projectile body 12.Type: GrantFiled: March 28, 2008Date of Patent: February 23, 2010Assignee: Techventure Investments Pty Ltd.Inventor: Leslie Mervyn Harrison

Patent number: 7658137Abstract: Methods and articles are provided for frangible slugs. A method of manufacturing a frangible slug includes heating substantially spherical metallic powdered particles, where substantially all of the powdered particles have diameters larger than 125 microns and smaller than 250 microns, to form heated powdered particles. The method includes heating a microcrystalline wax to form a melted wax. The method also includes combining the heated powdered particles with the melted wax to form a liquid mixture. The method further includes filling a payload cavity of a slug container with the liquid mixture to form a liquid mixture payload, where the slug container is configured to retain a solidified frangible payload as the frangible slug until impact with a solid object.Type: GrantFiled: April 22, 2009Date of Patent: February 9, 2010Assignee: Stresau West, Inc.Inventor: Michael A. Romero

Patent number: 7597037Abstract: A method for geometrically enhancing of the flight of a projectile fired from a weapon to an intended target, including development of a flat annular face on the outermost end of the ogive portion of the projectile, such flat annular face being oriented in a plane that is substantially perpendicular to, and concentric with, the longitudinal centerline of the projectile, and further including extraction of extraneous material from the meplat cavity of the projectile while establishing at least a void volume within the meplat cavity which is substantially concentric with the longitudinal centerline of the projectile and of substantially uniform size and geometry from projectile to projectile. Geometric alteration of the wall thickness of the flat annular face also may be provided. An enhanced projectile and a round of ammunition are disclosed.Type: GrantFiled: December 19, 2006Date of Patent: October 6, 2009Inventor: Harold F. Beal

Publication number: 20090183628Abstract: A method of making bullets on a progressive die wherein the progressive dies acts on a work piece having an elongated body with blanks at each end. The work piece is supported by a bandolier which is also formed in the progressive die. The progressive die forms each blank into a bullet, effectively doubling the output of the progressive die relative to a progressive die that acts upon a work piece that supports, or is, a single blank.Type: ApplicationFiled: June 6, 2008Publication date: July 23, 2009Inventors: D. PATRICK JONES, Michael Wayne Kelley, Richard Duane Pollick, Louis Cart Shaw, David L. Bertieri, JR., Jason Lee Lassinger, Mark P. Noah, James J. Marraccini

Publication number: 20080314280Abstract: The projectile of the present invention combines the advantages of both the solid and hollow point designs, featuring the initial ballistics of a solid projectile and the terminal (target) ballistic effects of a hollow-point projectile, without the risk of collecting undesired foreign matter into the cavity in the unfired configuration and also eliminating the possible feeding problems from the magazine to the barrel chamber by a simple manufacturing process. A plunger (4) is initially positioned in the expansion chamber (2) of the projectile. Upon sinking into the projectile body (1) no part of the plunger head (5) touches the internal surface of the expansion chamber (2) except for the bottom of such chamber (2) so that the plunger (4) has no active role in the expansion of the projectile upon impact.Type: ApplicationFiled: March 17, 2005Publication date: December 25, 2008Inventor: Laudemiro Martini Filho
