A cartridge is disclosed with a casing and a projectile, wherein external ballistic stability is provided by a center of pressure of the projectile being rearward of a center of mass of the projectile. The projectile includes flight control surfaces that cooperate with the bore of a barrel without requiring rifling or sabots. The projectile can include fin configurations that cooperate with the bore to form a gas check.

A rifle cartridge with a bullet has desirable penetration capabilities and controlled separation of components upon terminal impact. In embodiments of the invention, the bullet comprises a forward component, a lead core, and a copper jacket. The lead jacket having a leading edge portion that extends to the cylindrical mid portion. The forward component may have a forward pointed ogive portion, a cylindrical mid portion, a mid ogive portion, and a pair of cylindrical portions separated by an annular groove. The jacket having a cannelure at the annular groove and the casing upper lip crimped into the cannelure.

The invention relates to a cartridge having a projectile, and a case which is mounted on the projectile from behind and which has a case mouth at the front end, wherein the projectile has a tip, and at the rear this tip merges into a circumferential front guide band which defines the outside diameter of the projectile, and directly adjoining this front guide band in the direction of the projectile base, a circumferential case mouth receiving space which extends in the axial direction of the projectile and in which the case mouth engages is situated in the projectile. In order to reduce the twistless freebore to a minimum and build up the gas pressure early during firing, it is proposed that an exposed portion of the case mouth receiving space extending in the axial direction of the projectile is situated between the front guide band and the case mouth; i.e., the case mouth does not completely fill the case mouth receiving space in the direction of the nose of the projectile.

A duplex projectile cartridge system (e.g., 400) for use in a standard rifle (e.g., 10) has a front bullet (e.g., 320) and a substantially cylindrical back bullet (e.g., 440) coaxially aligned with one another. The front bullet's base is held in the cartridge case neck far enough to engage the back bullet's front surface so that the case neck simultaneously bears upon the front bullet and the back bullet. Optionally, the cartridge configuration orients the back bullet and defines one or more gas bypass lumens to allow expanding gas to initially bypass the back bullet and drive the front bullet distally to force an inter-bullet gap (e.g., “IBG” 480) upon firing.

An extended range, enhanced lethality 40 mm ammunition round. The round features controlled guidance and camera front end, which can be fired as fin stabilized with no appreciable spin, from an M320 grenade launcher. The round has a launching sleeve with an oversized propellant cup, to essentially double or triple conventional range, with sharp accuracy provided by the guidance system.

Ammunition for a conductive energy weapon. A receptacle includes a cavity accessible through each of a first opening in a first face of the receptacle, a second opening in the first face of the receptacle, a third opening in a second face of the receptacle and a fourth opening in a third face of the receptacle. A propellant unit is included within the cavity proximate the second opening and a projectile is included within the cavity proximate the second opening. A housing is coupled to at least the second face and the third face of the receptacle and is further configured to couple to the conductive energy weapon. The propellant unit releases a propellant into the cavity, in a direction substantially opposite the projectile's direction of flight, in response to a trigger pull of the conductive energy weapon, and the cavity directs the propellant in the projectile's direction of flight.

A cartridge assembly that includes a non-lethal projectile and a carrier configured for retaining and launching the non-lethal projectile. The carrier includes a housing including a combustion chamber, at least one escape aperture, a primer, and a case connected to the housing. The case encases the non-lethal projectile. The case and the housing collectively define a launch chamber that is fluidly connected to the at least one escape aperture. The launch chamber is configured for launching the non-lethal projectile out of the case. The at least one escape aperture is configured for metering pressurized gas from the combustion chamber to the launch chamber for launching the non-lethal projectile.
