Publication number: 20020178963Abstract: A jacket precursor, a pellet first core precursor, and a second core precursor are provided. The pellet and second core precursor are inserted into the jacket precursor. The second core precursor is pressed against the pellet so as to deform the pellet to fill a frontal volume of the jacket precursor as a first core with relatively less (if any) deformation of the second core precursor. An aft portion of the jacket precursor is deformed to contain the second core precursor as a second core. Preferred embodiments are formed substantially as drop-in replacements for existing bullets. A match embodiment features a lead rear core and a very light front core (e.g., a carbonate powder). A non-toxic embodiment comprises a tin front core and a harder rear core.Type: ApplicationFiled: November 9, 2001Publication date: December 5, 2002Applicant: Olin Corporation, a corporation of the State of VirginiaInventor: Henry J.

Patent number: 6158351Abstract: 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.Type: GrantFiled: July 22, 1996Date of Patent: December 12, 2000Assignee: Olin CorporationInventors: Brian Mravic, Henry J. Halverson, Deepak Mahulikar

Patent number: 6085661Abstract: 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.Type: GrantFiled: October 6, 1997Date of Patent: July 11, 2000Assignee: Olin CorporationInventors: Henry J. Halverson, Anthony F. Valdez

Patent number: 6070532Abstract: 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.Type: GrantFiled: April 28, 1998Date of Patent: June 6, 2000Assignee: Olin CorporationInventor: Henry J. Halverson

Patent number: 5814759Abstract: 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.Type: GrantFiled: February 3, 1997Date of Patent: September 29, 1998Assignee: Olin CorporationInventors: Brian Mravic, Deepak Mahulikar, Gerald Noel Violette, Eugene Shapiro, Henry J. Halverson

Patent number: 4735147Abstract: 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.Type: GrantFiled: February 27, 1985Date of Patent: April 5, 1988Assignee: Olin CorporationInventor: Henry J. Halverson

Patent number: 4653404Abstract: 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.Type: GrantFiled: November 4, 1985Date of Patent: March 31, 1987Assignee: Olin CorporationInventor: Henry J. Halverson

Patent number: 4610061Abstract: 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.Type: GrantFiled: June 10, 1985Date of Patent: September 9, 1986Assignee: Olin CorporationInventor: Henry J. Halverson

Patent number: 4574703Abstract: 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.Type: GrantFiled: March 1, 1984Date of Patent: March 11, 1986Assignee: Olin CorporationInventor: Henry J. Halverson
