Abstract
A novel resizing die (100/300) for a cartridge case has been provided for efficiently and quickly resizing a cartridge case during a reloading operation. The novel die includes a precise measuring system (122, 124, 108/122, 306, 108) for being able to accurately and precisely adjust the position of the resizing die when already threaded into an internal bore of a reloading press so that after a first resizing process is performed, the resizing die of the present invention may be precisely adjusted by the length that the cartridge's headspace distance is too long or too short so that the next resizing process will yield a cartridge headspace distance that is in substantial accordance with a predetermined length.
