  • Patent number: 6050169
    Abstract: A fired rifle cartridge is resized in the cartridge neck area for reuse. A first die set is employed to compress the cartridge neck such that the inner surface of the neck fits a standard size bullet. A second die set is used to expand selected areas of the cartridge neck to snugly fit the firing chamber. The resultant ammunition round can be fired with a greater degree of accuracy than ammunition resized by prior art procedures, because the longitudinal axis of the cartridge neck coincides with the bore axis of the firearm.

  • Patent number: 5313869
    Abstract: A shell plate for being indexed in angular steps is on a carrier which is, in turn, mounted to the upper end of the reloader ram. Indexer rod engageable elements such as cylindrical equiangularly spaced apart pins project downwardly from the bottom of the shell plate. An indexer rod is carried in the shell plate carrier. When the ram is driven to nearly its lowermost position, the manual operating lever is near the end of its swing at which time it abuts the indexer rod for the latter to engage one of the pins to rotate the shell plate. The indexer rod is retracted and reset by having it slide down a guide track from the uppermost position of the ram and the guide track is angulated in part to be engaged by the rod and retracted. The reloader is distinguished by indexing the shell plate only when the ram is within a few millimeters of its lowermost limit.
