Ammunition cartridges for hunting big game with an AR15 rifle are provided while maintaining a size of the ammunition cartridge that permits multiple ammunition cartridges to be inserted into an AR15 rifle magazine in alternating side by side relation. Each cartridge has a rim diameter of 0.422 inches, extractor groove and a slight tapered main body base of 0.36°. In one embodiment, the main base body extends to form a cartridge with total length of 1.8 inches and nominal body taper of 0.020 inches to accept a bullet with a diameter of 0.400 inches. In other embodiments, the main body base extends to a shoulder and a neck to form a cartridge with a total length of 1.66 inches. The shoulder tapers to the neck at a 35° angle with a nominal body taper of 0.014 inches. These embodiments accept bullets with diameters of 0.277, 0.284 and 0.308 inches.

The present invention provides a subsonic ammunition cartridge including a polymeric casing body comprising a generally cylindrical hollow polymer body having a body base at a first end thereof and a mouth at a second end to define a propellant chamber; a propellant insert positioned in the propellant chamber to reduce the internal volume of the propellant chamber, wherein the propellant chamber has an internal volume that is between 25 and 80% less than the open internal volume of a standard casing of equivalent caliber; and a primer insert positioned at the body base and in communication with the propellant chamber.

A cartridge casing of a cartridge for a lever action firearm, the cartridge casing comprising a rim comprising a flat front face configured to provide a gripping surface for an extractor of the lever action firearm to remove the cartridge casing of the cartridge after firing of the lever action firearm, the rim having a radial gradient that decreases from a maximum radius at a first location on the rim that is prior to the flat front face to a minimum radius value at a second location on the rim corresponding to the flat front face.

The invention relates to fragmenting projectiles. In order that all projectiles of a*waffe*Bug projectile type have the same point of impact, i.e., the same projectile weight, the same center of gravity and the same geometry, and that the marksman can set the fragmentation behavior solely by selecting the projectile, fragmenting projectiles having defined fragmentation in steps for the same point of impact, designed as two projectile types, namely as partially fragmenting projectiles or as jacketed projectiles, are proposed, wherein all fragmenting projectiles of a projectile type have the same projectile weight, the same center of gravity, and the same geometry, a fragmentable core is arranged in the front nose region for both projectile types, all fragmentable cores of a projectile type have the same density and differ from each other in the weight of the fragmentable core depending on the fragmentation, and all projectiles of a projectile type having the same weight of the fragmentable core have an identical marking that can be seen or felt from the outside.

A 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 bullet having a forward nose portion with a plurality of cutaways spaced circumferentially about the nose portion. The copper jacket having a leading edge portion positioned at the cutaways.

The invention relates to an igniter unit for a munition, comprising a housing and at least one pyrotechnic charge, the igniter unit comprising a control and communication device arranged in the housing and at least one interface connected to the control and communication unit and arranged in the housing.

A cartridge for improving explosive dynamics of ammunition. The cartridge comprises a casing comprising a powder chamber. The powder chamber comprising a powder chamber length among a plurality of inner chambers. The plurality of inner chambers comprise at least a first chamber, and a second chamber. The casing comprises a powder chamber casing portion comprising a portion of the casing wrapped around side portions of the powder chamber. A cartridge chamber inner wall comprises an inner portion of the powder chamber casing portion. The powder chamber casing portion comprises a plurality of thicknesses which comprise at least a first thickness and a second thickness.

The present invention discloses a lightweight hybrid cartridge case (100) for a cartridged ammunition and a method of manufacture (200). The lightweight hybrid cartridge case (100) includes a cap (110) with a cylindrical sidewall (112) connected a base (120); a polymer shell (150) is insert-molded onto the sidewall of the cap; and an overmolded sleeve (180) is formed to cover the metal-polymer joint between the cap (110) and the polymer sleeve (150). The cylindrical sidewall (112) covered by the overmolded sleeve (180) has a plurality of stepped ridges (132, 132a), preferably with one stepped ridge (133) having a C-stepped edge (134).

One embodiment of the present invention provides a making a polymeric ammunition having wicking texturing about the projectile end.

A cartridge with a bullet has desirable penetration capabilities and controlled separation of components upon terminal impact.
