Brass Preparation: With bulk rifle brass you may sometimes notice a few case mouths are “out of round” or slightly dented below the shoulder. To straighten the case mouth, run the case part way into the sizer die and let the expander ball straighten the brass.  To prevent the case neck from stretching, be sure to lubricate the case neck inside the case mouth. In the event a case becomes stuck, purchase a stuck case remover; don’t use pliers, screwdrivers or other common household tools which could damage your sizing die.
