  • Patent number: 6182574
    Abstract: A projectile designed to be fired from firearms. The projectile has a generally conically shaped jacket having a forward tip, rear base, a body portion, and a central axis. The jacket is formed of a first metal. Located inside the jacket is a generally conically shaped penetrant which is formed of a second metal. The penetrant is formed with a forward tip, a rear base, a body portion, and a central axis. The tip of the penetrant is positioned substantially adjacent the tip of the jacket with their longitudinal axis being aligned. Finally, a core, which is formed of a third metal, fills the jacket and is located about the tip, body, and base of the penetrant. The third metal has a hardness less than that of the first and second metals while the second metal has a hardness greater than that of the first metal.

  • Patent number: 6176186
    Abstract: The present invention is directed toward an expansion projectile capable of achieving complete expansion at a subsonic speed. The projectile consists of a malleable core and a jacket of more structural integrity. Complete expansion is achieved through the use of a guaranteed misalignment of jacket scoring in relation to premade cuts within the projectile's core. Expansion is further facilitated through use of a gradient density bearing insert which is contained within the core. Upon impact of the projectile at its target the bearing insert will rupture and expand. This will guarantee complete disintegration of the projectile.

  • Patent number: 5763819
    Abstract: The present invention relates generally to small arms bullets and relates in particular to frangible bullets and ordinance which fragments following penetration of a variety of obstacles prior to encountering the intended target zone. The disclosure relates specifically to small arms bullets which have a high likelihood of fragmentation after target zone penetration causing a significant crush cavity following passage through obstacles including clothing, glass, building materials and other structures. The disclosed bullet design is produced in a simple and inexpensive process, provides high accuracy and fragmentation and penetration in a 5 to 15 inch target zone, at either sonic or subsonic velocities, following penetration of shielding obstacles. The bullet disclosed is of a weight and design which will permit operation at sonic or subsonic velocities, without jamming, in civilian and military small arms including automatic weapons.

  • Patent number: 5349907
    Abstract: Disclosed is a projectile that has high velocity at short range. The projectile has a body of material that is lighter, more lubricous and more deformable than a partial jacket on the rearward portion of the projectile. The jacket defines an annular array of apertures on the outer diametrical surface of the jacket and the body has peripheral zones that extend into the apertures far enough to be flush with the outer diametrical surface. The peripheral zones not only provide a physical lock between the body and jacket but also lubricate the interface between the projectile and the gun barrel along which the projectile travels during firing of a gun. The apertures are configured to allow the body to erupt radially outward through the jacket's side wall and form a relatively wide, shallow dispersal pattern when the projectile impacts a target. An optional core within the plastic body enhances the body's radially outward dispersal upon the projectile's impact with a target.

  • Patent number: 5185495
    Abstract: The invention is an improved partially jacketed projectile intended for small arms use. The projectile includes a central stem integral with a rear wall of the projectile, the rear wall in turn being integral with the partial jacket. A core surrounding the stem and encased by the jacket is softer than the material forming the stem, rear wall and jacket. The jacket retards core petalling during initial projectile impact whereas the rear wall configuration enhances petalling when the projectile achieves subsequent target penetration.

  • Patent number: 5097768
    Abstract: The invention is a firearms projectile having an improved petalling action upon impacting a target. The projectile includes a slug whose head is separated into petalling elements by fins of a softer material than that of the slug, the head defining a central recess from which the fins radiate. The slug has a core therein which is forwardly and rearwardly tapered and is configured to assist the outward movement of the petalling elements after the projectile impacts. The cylindrical walls of the projectile provide a limited, controlled degree of longitudinal support to the petalling elements and the projectile includes means to force the cylindrical walls outward and away from the petalling elements once impact begins.

  • Patent number: 4776279
    Abstract: An improved expanding ballistic projectile is disclosed which has an inner core of dense relatively soft, deformable material, and an outer jacket of malleable material. A central axial recess is provided in the nose portion of the inner core and a central opening is provided in the nose of the outer jacket coincident with the recess in the inner core. A generally cylindrical expansion-initiating insert member, having a generally symmetrically tapered rear portion and a generally symmetrically tapered nose portion and of a hardness greater than the inner core, is disposed in the recess. This cooperates with a plurality of circumferentially spaced longitudinal slits formed in the outer jacket to achieve controlled uniform expansion upon impact.
