The Dillon Precision Carbide Sizing Die is full-length, to minimum tolerance, sizing cases down to function in semi- and full-automatic firearms. This is a carbide size / deprime die, however it is still necessary to lubricate the cases prior to resizing. The increased scratch resistance and die longevity of carbide make it a superior choice over a conventional steel die. In the event of a stuck case, the design of the depriming assembly allows it to function as a stuck case remover.
