The routine depends on what your reforming.In my case I'm resizing some 30-06 Mil brass to .280 Rem.I need to be careful on setting the full length die just right due to the shorter 06 case to prevent misfires.After resizing I have what is called a "false shoulder".I then use starter loads to fire form the case' to 280 and the shoulder goes away.Other cartridges sometimes require more steps.You need to be specific what cases you're working with.
