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.
