The present invention provides polymer ammunition having a primer insert having: a top surface; a bottom surface opposite the top surface; a coupling element that extends from the bottom surface, wherein the coupling element comprises an interior surface and an exterior surface, wherein the interior surface comprises: a transition region that transitions from the bottom surface to a second segment wherein the transition region has a radius of from 0.02 to 0.2; a first segment extending from the second segment and terminates at a tip, wherein the first segment has a first segment distance from 0.02 to 0.18 inches and the second segment has a second segment distance from 0.02 to 0.18 inches, wherein the second segment has a second segment angle from +3 to −3 degrees relative to the first segment angle and the first segment has a first segment angle from +6 to −6 degrees from perpendicular to the top surface; a primer recess in the top surface that extends toward the bottom surface; a primer flash aperture positioned in the primer recess through the bottom surface; and a flash aperture groove in the primer recess and positioned around the primer flash aperture and adapted to receive a polymer overmolding through the primer flash aperture.

An ammunition assembly is provided, which includes a projectile and a fixture, where the projectile includes a penetrating, a sabot and a sabot holder, the sabot is sleeved on an outside of the penetrating, the sabot is of a split structure, the sabot holder is sleeved on an outside of the sabot, the sabot holder is located at one end of the sabot far away from the penetrating; the projectile is slidably provided in the chamber; the fixture includes clamping blocks, the clamping blocks are movably provided in the gun barrel, and the clamping blocks are capable of extending into the chamber and blocking the sabot holder.

A magazine of a pistol for cartridges with a case rim, having a hollow magazine body for accommodating the cartridges in two vertically offset rows, a base plate, a feeder, which is guided in a displaceable manner in the magazine body, and a compression spring between the feeder and the base plate, wherein the upper end region of the magazine body forms a narrowing, in which the two rows of cartridges are guided together to form a single row. In order to ensure a reliable feed of the cartridges despite the case rim, in the longitudinal center the side walls have inwardly directed beads which run over the entire height of the side walls and merge, in the upper region, into converging guide ribs, and the feeder forms a bearing surface, which is convex in the longitudinal direction and on which a cartridge located thereon can alter its angle of inclination in relation to the horizontal.

The Gun Disabling Mock Ammunition is a device made to the same outward dimensional specifications and aesthetic characteristic as actual firearm ammunition; however, when attempted to be fired from a firearm, the effect is a non-hazardous, exothermic reaction taking place within the ammunition cartridge, producing heat substantial enough to bond the Gun Disabling Mock Ammunition to the inside of the chamber of the firearm, rendering the firearm immediately disabled and the chamber destroyed. This is accomplished while posing no risk of injury to the user or bystanders. The components of the Gun Disabling Mock Ammunition are non-toxic, non-hazardous, and chemically stable. Through use of the Gun Disabling Mock Ammunition, a reduction of deaths, injuries and crimes resulting from the intentional and unintentional use and access of unsecured legal, illegal and insurgent-force firearms can be achieved.

The present invention provides a polymer ammunition cartridge having a primer insert having: a top surface; a bottom surface opposite the top surface; a coupling element that extends from the bottom surface, wherein the coupling element comprises an interior surface and an exterior surface, wherein the interior surface comprises: a transition region that transitions from the bottom surface to a second segment wherein the transition region has a radius of from 0.02 to 0.2; a first segment extending from the second segment and terminates at a tip, wherein the first segment has a first segment distance from 0.02 to 0.18 inches and the second segment has a second segment distance from 0.02 to 0.18 inches, wherein the second segment has a second segment angle from +3 to −3 degrees relative to the first segment angle and the first segment has a first segment angle from +6 to −6 degrees from perpendicular to the top surface; a primer recess in the top surface that extends toward the bottom surface; a primer flash aperture positioned in the primer recess through the bottom surface; and a flash aperture groove in the primer recess and positioned around the primer flash aperture and adapted to receive a polymer overmolding through the primer flash aperture.

A firearm projectile is provided to promote a yaw effect on material entry by the projectile and to enhance wound channel formation on entered material. The firearm projectile comprises an elongated body, having a surface formed as a surface of revolution. It further consists of an ovoid forward portion and a cylindrical rear portion.

The present invention provides a projectile device and a method of manufacture of a projectile device and in particular, to a pistol bullet and a rifle bullet and method of manufacture of same. In one embodiment, the projectile apparatus has a cylindrical body portion having a diameter, a front nose section tapering from a most proximal point of the projectile to the cylindrical body portion, and a rear tail section connected to the body portion and extending to the most distal point of the projectile, in which the front nose portion comprises a plurality of twisting depressions forming troughs.

The present disclosure provides a cartridge that modifies the .223 cases to achieve a cartridge length of 38.3 mm for use with a bullet (e.g., 110 g). The present cartridge system allows the use of a 30-caliber bullet to be used in an AR15 rifle/pistol platform. The decreased cartridge length optimizes the powder burn rate and pressure, which in turn has a greater effect on the ballistics of the round. The present system yields 300-400 ft/s higher velocity over the .300 Blackout in rifle length barrels and greater than 500 ft/s in shorter pistol barrels.

The present invention provides an ammunition cartridge having a primer insert having a top surface opposite a bottom surface and a extraction flange that extends circumferentially about an outer edge of the top surface; a coupling element that extends from the bottom surface, wherein the substantially cylindrical coupling element is adapted to receive a polymer overmolding; a primer recess in the top surface that extends toward the bottom surface, wherein the primer recess comprises a recess bottom and a circular recess side wall; a primer flash aperture through the recess bottom that extends through the bottom surface, wherein the primer flash aperture is adapted to receive a polymer overmolding to form a flash hole; and a groove in the primer recess positioned around the primer flash aperture adapted to receive a polymer overmolding, wherein the groove extends at least partially over the bottom surface and the circular recess side wall and the groove is adapted to receive polymer through the primer flash aperture and over the bottom surface and the circular recess side wall.
