A lead free ferromagnetic article is disclosed. The article is a compacted composite having a heavy more dense constituent that is preferably ferrotungsten and a less dense second constituent that is either a metal alloy or a polymer. The ferromagnetic constituent is present in an amount sufficient to impart the article with ferromagnetism. The ferromagnetic property allows fragments of the article, such as a projectile, bullet or shaped charge liner to be separated from dirt or other environments.

Ferromagnetic bullet

A small caliber non-toxic penetrator projectile has a first core and a second core tandemly aligned and enveloped by a jacket. The first core has a hardness greater than the hardness of the second core that has a Brinell hardness of between about 20 and about 50. The hardness of the second core is significantly higher than the hardness of lead and when the first core strikes a target, the second core resists compressive bulging. As a result, more kinetic energy is transferred to the first core rather than diffused along the surfaces of an armored target. The more efficient transfer of kinetic enables the use of lower density second cores, such as annealed copper.

Small caliber non-toxic penetrator projectile

A projectile having improved accuracy when fired over long ranges is formed from a monolithic block of a copper alloy. Proceeding from a nose to a heel of the projectile, is a fore portion with arcuate side walls, a body portion of substantially constant cross-sectional area that minimally contacts a rifled gun barrel, a drive band having a diameter effective to seal propellant gases and an aft portion that continuously decreases in diameter terminating at the heel. A cylindrical bore extends from an opened end at the nose to a closed end proximate to a transition plane between the fore portion and the body portion.

High accuracy projectile

A composite lead-free bullet is disclosed comprising a heavy constituents selected from the group of tungsten, tungsten carbide, carballoy, and ferro-tungsten and a second binder constituent consisting of either a metal alloy or a plastic blend.

A high velocity traced armor penetrating subcaliber projectile core having sealed radial spin-up notches on its base is disclosed. Also disclosed, is a plastic sabot for launching a traced subcaliber high velocity armor penetrating projectile core, which sabot is a cup shaped plastic body with a sealed passageway through its base and longitudinal weakening slots on the inside of its walls, the slot extending only part way down the inner surface of the wall to leave a cylindrical sealing surface adjacent the sabot base, whereby to provide a waterproof seal surrounding the rearend of the core and the tracer charge.

Ammunition sabot and projectile

A high velocity ammunition sabot with internal notches of special design to give reliable break-up upon exit from a rifled gun barrel due to centrifugal forces.

High velocity notched ammunition sabot

A projectile for a centerfire cartridge that achieves maximum energy transfer with limited target penetration when fired from snub-nosed pistols. A hollow point lead bullet is provided with an aluminum jacket of sufficient hardness to avoid fouling the pistol barrel and which allows the cartridge containing the projectile to feed reliably in auto-loading pistols and yet does not restrict normal expansion of the bullet upon impact with the target. The jacket extends into the nose recess of the bullet and covers the peripheral portion of the bullet base, whereby the jacket is securely fastened to the bullet and separation subsequent to impact is prevented. The jacket is uniformly notched at the nosetip annulus to weaken the aluminum jacket and promote upset at surprisingly low impact velocities. A method of fabricating the projectile is also disclosed in which a cup-shaped aluminum jacket is partially filled with a lead core and simultaneously the cup base is notched before being formed into a hollow point bullet nose configuration. The notches can thus be uniformly controlled in contrast to slitting or cutting before or after forming in which the sharpness and force applied to the cutting knife governs the size of the slit or cut in a hard to control fashion.

Low velocity expanding projectile

A high velocity ammunition sabot of brittle material which has sufficient strength to withstand the forces of being launched from a rifled gun barrel but which fragments almost immediately upon exit from the barrel due to centrifugal forces. A polyetherimide material is preferred, although materials of equivalent properties could be used.
