Decapping dies allow you to deprime and clean your cases prior to sizing. The small decapping die will handle 22 thru 50 calibre cases with lengths up to 2.625. An optional decapping rod for this die is designed to work with all 17 calibre cases and will accommodate the small .060 flash holes found on the BR and PPC cases. For longer case lengths up to 3.0 use the large decapping die. Note: the large die will not accommodate a neck diameter of less than 25 calibre.
