ABSTRACT:
An ammunition cartridge case reforming die to be used in reloading operations having a central bore defining the external configuration to which the outer surface of the cartridge case is to be reformed. A mandrel having an outer surface of a configuration to which the inner diameter of the cartridge case neck is to be formed is mounted co-axially in the bore. A stop element adjacent the mandrel has a stop surface which extends radially outwardly from the mandrel toward the bore inner wall. The stop surface is positioned and angled such that it will limit the lengthwise growth of the case neck during resizing and also produce a chamfer on the inner mouth surface of the case neck.
