Re: Spindle and decapping pin out of line?
There should be instructions with your dies for adjusting this. I've tried a couple different ways. Using the brass to center the stem, and holding the stem while tightening the lock nut, snug enough to not come lose, but not so tight I can't get the nut lose to adjust it again later if needed.
There are only two seasons: Hunting season, and Getting Ready for Hunting season. -DAD
