Thanks KansasSasquatch, Hornady makes a fine set of rifle dies in the "New Dimension" I can't imagine why anyone would not pay the $5-$10 extra and get them. I owned a 221 fireball, and at the time the dies were not common, or they commanded and extra cost. I purchased a set of Hornady New Dimension FL dies and never had problems forming brass from 223.
Back on topic I forgot about Lee they go about the lock ring using a o-ring method that keeps the die loose enough to self center in the threads, yet enough tension from o-ring to lock the ring in place. If you use a die lock ring with a setscrew (really any lock ring) before locking the ring in place put some pressure on the die by using a piece of brass (just like you would full length size)to size with, or a washer (washer between shell holder and die), then raise the ram until the slack is removed from the die threads, lock ring threads, press threads. This should be done with any die, just takes a few extra, seconds I'm sure all of this is probably just old info that everyone already knows, but maybe someone can use it.
