Abstract: A cartridge shell reloading tool for resizing empty cartridge shells and ejecting them from the reloading tool. The tool comprises a housing having a longitudinal bore threaded at one end to receive a resizing die which, in turn, receives the cartridge shell. The other end of the longitudinal bore of the tool housing slidably supports a spindle having one end which is received within the cartridge shell and engages the base of the shell such that the force of a coil spring carried within the housing bore and acting against an enlarged portion of the spindle ejects the shell from within the die bore after the shell has been properly shaped.The upper end of the reloading tool has a threaded member extendable into the housing bore for selected mechanical abutment with the spindle to aid the coil spring in ejecting the shell from the sizing bore of the die in the event the shell is jammed therewithin.
