  • Patent number: 9207052
    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.

  • Publication number: 20150107480
    Abstract: To produce lead-free projectiles, iron and copper are melted at a predetermined ratio and rapidly quenched to yield a fine-grained microstructure with uniformly distributed copper and iron phases. The iron-copper alloy may be made into a powder through atomization, with the iron-copper molten metal being dispersed using a rapidly moving gas, liquid stream, or via mechanical dispersion. The step of forming the bullet may include uniaxially pressing and solid-state sintering of the atomized powder, including heating at a temperature below 1083° C., the melting point of copper. Alternatively, the step of shaping the mixture into a bullet-shaped form may include casting the molten mixture into a mold. A ceramic powder may be added to the copper-iron mixture prior to forming to produce a frangible projectile. The method may further include the step of adding another elemental powder to enhance strength, toughness, density, or hardness.

  • Publication number: 20150033973
    Abstract: 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.

    Abstract: A lightweight projectile having an integrated driving band positioned around the exterior of the polymer base of the projectile for engaging the rifling of a barrel to impart spin stabilization to the projectile. The driving band protrudes from the polymer base to minimize the contact between the polymer base and the rifling to reduce friction between the barrel and the projectile as the projectile is fired. The reduced friction allows the lightweight projectile to be propelled with minimal propellant force while still retaining the ballistic advantages of a spin stabilized projectile.

    Abstract: 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.

  • Publication number: 20090183628
    Abstract: 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.

  • Publication number: 20080314280
    Abstract: 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.

  • Publication number: 20080216700
    Abstract: The present invention relates to a bullet made of a single solid piece of deformable metal, containing no lead or toxic material, easily deformable but without fragmentation in a soft environment with a high rate of energy transfer, and a high level of solidity in hard targets, retaining most or its total initial weight while penetrating those targets. Said objects are achieved by constructing a solid monobloc bullet with a cavity on the longitudinal axis which is opened towards the fore end of the bullet. The method of construction encompasses a sequence of simple operations: cutting of a cylinder blank of soft material, forming a cavity centered on the longitudinal axis, and forming an ogival or conical form, with external pre-cuts to foster an homogenous deformation.

  • 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.
