  • Ammunition reloading device
    Patent number: 11874097
    Abstract: An ammunition cartridge case reloading die has a die body defined by an interior bore and a bore opening, and a retention cap attachable to the die body. A cartridge case tool is fixed to the retention cap in axial alignment with the interior bore, and a tip of the cartridge case tool is at a proscribed distance relative to the bore opening. A centering shuttle is in sliding engagement in the interior bore of the die body, and defines a shuttle bore through which the cartridge case tool passes, and a reverse taper opening receptive to the cartridge case. The die may has a biasing element disposed within the interior bore between the centering shuttle and the retention cap, with movement of the centering shuttle within interior bore of the die body being dampened by the biasing element.
