My Hornady seating die has always required that you screw the seating depth adjustment almost all the way in to seat 55 gr. bullets so they will fit my magazines. Recently I purchased some of the factory second 55 gr. with poly tips from Midway. The die runs out of adjustment and will not seat the bullets enough to work through my magazines. I need about 0.020" more seating depth. I disassembled the die and it appears that the plastic seating stem that contacts the bullet nose might be worn just enough to be causing the problem. Anybody ever wear out a part of a seating die? I guess I will contact Hornady for a new part.
