    Abstract: The present invention provides an ammunition disabler with a material capable of being selectively changed in response to an energy wave for preemptively disabling ammunition. In at least one embodiment, the ammunition disabler includes a material selectively structurally changeable from an operative state to a deactivated state upon exposure to an energy wave is provided, where the material is positioned at least partially between the firing pin and the priming compound when the ammunition is chambered within the firearm (with the priming compound positioned between the material and the propellant), and related systems, methods and uses. The material may be contained within the primer cup with the priming compound. The material may be positioned adjacent to the priming compound in direct or indirect contact or in close proximity. The material may be positioned externally from the primer cup.

    Abstract: A vented pyrotechnic device is provided that hermetically seals the pyrotechnic material contained therein under ambient storage conditions, but vents upon exposure to elevated-temperature conditions at or below the outgassing temperature for the pyrotechnic material. The vent passage communicating the chamber containing the pyrotechnic material with the exterior of the device is initially sealed at ambient storage conditions by a temperature-sensitive material. When exposed to a predetermined temperature condition, the temperature-sensitive material undergoes a physical change unblocking the passage and permitting venting of off gases produced by the pyrotechnic material.

    Abstract: The firearm cartridge has an upper chamber adapted to house gunpowder and a bullet, a lower pocket adapted to house a primer, and a flash hole extending there between. The lower pocket has a ledge disposed generally perpendicularly to the flash hole. The flash hole is formed with a perimeter wall that has a convex curvature adjacent to the ledge of the primer pocket. Likewise, a percussion nipple adapted for use in a black powder rifle has an elongated bore formed with relatively larger and smaller diameter portions connected by a shoulder, and the shoulder has a convex curvature adjacent to the larger diameter portion of the bore. The tool for forming the foregoing shapes has a tip provided with a concave curved surface corresponding to the convex curvature of the flash hole perimeter wall on the cartridge or to the convex curvature of the shoulder in the elongated bore of the percussion nipple.
