    Abstract: The micrometer adjustable ram is used within a frame having die mount and lever. A die is releasably secured within the die mount and a firearm cartridge is releasably secured to the end of the ram for resizing or bullet reseating. In operation, the ram extends into an extended position and the cartridge held at the end of the ram is inserted into the die held within the die mount. To adjust the length of the cartridge that is inserted into the die and thereby the amount of resizing and seating done to the cartridge, a micrometer assembly is provided within the ram that can be adjusted by the reloader. Furthermore, the micrometer assembly can be locked prior to use to assure that the ram, and cartridge held thereon, are coaxially aligned with the center axis of the die for more precise and repeatable resizing and reloading.

    Abstract: An ammunition cartridge comprised of a projectile inserted in, and mechanically connected to, a metal cartridge case assembly having a propulsion chamber and a base, and an energetic propellant disposed in the propulsion chamber, includes a base plug in which is mounted an igniter with an energetic primer. During manufacture of the cartridge, a fusible support ring is incorporated into a metal cavity. The cartridge base includes a cavity allowing the fusible material to solidify at ambient temperatures. When exposed to heat from an external fire, the fusible support plug liquefies losing its strength and subsequently, when a propellant or primer off-gasses or auto-ignites the pressure from the reaction ejects a metal plug or lid from the cartridge case base, creating a void that allows the propellant and primer to combust in an unconfined space.
