The present invention provides a primer insert for use in a polymeric ammunition cartridge includes 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 at least partially over the circular recess side wall and the groove is adapted to receive polymer over the bottom surface and at least partially over the circular recess side wall.

A linear shaped charge comprising a body comprising a foam material, a first explosive element, a second explosive element, a liner and a channel at least partly between the first explosive element and the second explosive element. A related structure is also described, with a first cavity configured to receive a first explosive element and a second cavity configured to receive a second explosive element.

A cover provided for a powder measure that includes a tubular sleeve to fit over hopper reservoir walls. The cover may include an informational card slot, and/or a moral patch. The cover may also include a viewing window slit or slits to provide viewing information on the fill level of the hopper while the cover is applied.

An ammunition reloading system my have at least one local or remote controller connected to a volumetric dispenser and a kernel feeder. The controller can direct to flow of powder, such as gunpowder, to a vessel from the volumetric dispenser with a first granular resolution and from the kernel feeder with a second granular resolution where the second granular resolution is smaller than the first granular resolution.

The disclosed technology regards a reusable, non-pyrotechnic diversionary device having a housing assembly which receives and supports a pressure manifold, activation assembly, and a lighting assembly. The housing assembly includes a vessel, a main chassis, and a transparent lens. Positioned within the main chassis is a pressure manifold which supports a compressed gas source. A puncture pin is provided in the activation assembly, and aligned with the compressed gas source to facilitate puncture of the source. The disclosed technology further regards a reusable, non-pyrotechnic diversionary assembly having a housing assembly and a reloading tool. The reloading tool has an externally threaded inner body with an aperture at its distal end sized to receive the puncture pin, and an outer body sized and internally threaded to rotatably receive a portion of the inner body in its shaft, allowing the inner body to traverse through and from the shaft at its distal end. A threaded interface is provided on the outer body of the reloading tool to align with the first support structure of the pressure manifold. The inner body rotationally translates within the outer body to position the distal end of the inner body relative to the puncture pin and allow it to translate the puncture pin from an active position to a secured position.

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 booster explosive (10) comprises a canister body 12 within which is a cap well (20) having disposed therein a detonator (24). A protective sleeve (28) encloses the cap well (20) except for that portion of the cap well, the active portion (20d), which encloses the explosive end section (24a) of detonator (24). The protective sleeve serves to attenuate the force of shock waves from nearby prior explosions acting on the detonator (24). An annular air space (32) may be provided between protective sleeve (28) and cap well (20) to further attenuate the force of such shock waves. Attenuation of the shock waves reduces the likelihood of damage to detonators (24) by prior nearby explosions.

An improved process provides high-density pre-form billets that meet dimensional limitations required for case-load tooling. Previous isostatic fill procedures were improved in two ways to accommodate varying bulk densities or powder compositions. First, during the isostatic fill procedure, the powder fill is subject to both a high frequency vibration and a high amplitude, low frequency impulse. The combination of these two inputs is critical to ensure polymer bonded explosives pack to consistent densities. Second, unlike in conventional practices, the fill rate is kept constant throughout the entire fill process and the mold is completely filled by the time the required powder mass has been dispensed.
