FWIW: After getting tired of bunging up the threads with normal "locking" screws that screw directly into the die body, I just went out and bought a dozen Hornady rings that constrict the ring, not ding up into the threads. I then replace the original rings whenever I have to readjust a die body setting.

(Or are you now going to tell me they're all made by the same people as Forster's ?)
