    Abstract: A reduced signature weapon cartridge is provided which, when fired, produces little or no muzzle blast or noise signature. In particular, a reduced signature weapon cartridge of the present invention comprises a movable piston disposed within the cartridge, disposed in between the high pressure chamber and the projectile. When fired, propellant gases rapidly force the piston forward within the cartridge case, thereby launching the projectile at a subsonic velocity, thereby eliminating the conventional noise signature associated with supersonic velocities. Thereafter, the propellant gases are slowly released from the cartridge case via perforations formed within the piston, grooves formed in the periphery of the piston, or via a gap between the piston and cartridge wall, thereby reducing or eliminating the conventional muzzle blast.

  • Patent number: 7096793
    Abstract: A projectile including a spherical core and a hook or loop outer cover, has an overall diameter, including the cover which is equal to or less than an internal diameter of a 68 caliber paintball gun for use in the gun in place of paintballs. The diameter of the projectile permits gravity fed, drop loading of projectiles into a conventional paintball gun barrel without an compression of the projectile being required whatsoever. The resultant small gap surrounding the projectile within the barrel permits some pressurized gas to escape around the projectile when firing, thus limiting the velocity of the projectile to a safer velocity for closer range use of conventional paintball guns. A gun is also described having a shuttle for pushing a projectile through the barrel thereof by action of a stretched resilient band. The barrel is sized similarly to a conventional 68 caliber paintball gun for firing either paintballs or the projectiles described herein.

  • Patent number: 6772695
    Abstract: Projectiles or war-heads with an inner arrangement for the formation of bulging zones (4,4a) are proposed, comprised of an enclosed bulging medium (1) which is terminal-effective ballistically substantially ineffective and is radially enclosed by a penetration material (2) which is terminal-ballistically effective, with the bulging medium (1) having a lower density as compared with the enclosing penetration material (2). This leads to the effect that on impact or on penetrating a target plate (3) the bulging medium (1) remains behind relative to the encompassing terminal-ballistic effective body (2) and is laterally increasingly bulged by the bulging material (1) which continues to flow in from behind. As a result of the high pressures, a conical (crowned) pressure and bulging zone (4,4a) is formed dynamically, which zone radially widens or fragments the passing ambient effective material (5,5a).

  • Patent number: 6745698
    Abstract: A frangible projectile for gun ammunition wherein the projectile includes a core formed from one or more metal powders which are pressed into a self-supporting compact and incorporated into a metal jacket. The metal jacket is initially cup-shaped (generally cylindrical in overall geometry) with an open end and a closed end. In accordance with one embodiment of the present invention the closed end of the jacket becomes the trailing end of the projectile. In another embodiment, the closed end of the jacket becomes the leading end of the projectile. In either embodiment, that surface of the closed end of the jacket which faces inwardly of the volume of the jacket is indented and stressed over substantially its entire area in accordance with a pattern which enhances the frangibility of this closed end of the projectile when the projectile strikes a target.

  • Patent number: 6684792
    Abstract: A munition in the form of a projectile contains a dart having a body terminating in a front tip and ductile hammer block in the form of a ferrule engaging at least a part of the dart. The dart is formed of sections the diameters of which increase from the back to the front of the dart body, forming support shoulders. A recess in the hammer block has a shape corresponding to the dart body shape received in the hammer block. Hammer block sections form thrust shoulders which engage the corresponding dart support shoulders. When the projectile impacts a target, the thrust shoulders push against the dart support shoulders, causing the ductile hammer block to open and flare out.

  • Publication number: 20030221580
    Abstract: A powder-based projectile useful in the manufacture of gun ammunition comprising a jacket having an inner volume which is tapered from a maximum diameter adjacent the open end of the jacket to a minimum diameter adjacent the closed end of the jacket and a core formed outside the jacket and having a complementary tapered geometry with respect to the inner volume of the jacket. Projections from the outer surface of the core are embedded within the inner wall of the jacket to enhance the spin stability of the jacket/core combination and to enhance the frangibility of the projectile upon it striking a target. A method for the manufacture of the projectile is disclosed.

  • Patent number: 6581522
    Abstract: A projectile for being propelled toward a target includes a cylindrical body of Type 55 Nitinol that has a soft martensitic state that is readily deformed by rifling in the bore of a gun barrel to form grooves which ride on the rifling to spin the projectile. The Nitinol has a low coefficient of friction with the steel barrel and is sufficiently strong to prevent shedding particles or depositing projectile material in the bore. On impact with the target, the Nitinol undergoes a strain-induced shift to an ultra-high strength state in which the projectile is capable of remaining intact and concentrating its full energy on the small area of contact for maximal penetration and damage to the target instead of mushrooming widely and spreading its energy over a wide area as conventional projectiles do. Projectiles in the form of bullets, shotgun slugs, penetrating warheads, caseless ammunition and artillery shells are described.
