I have a couple dies that don't cam over when setup for .002-3" shoulder bump and have no issues with consistent sizing with proper lube.
The Hornady lock rings have wrench flats, I don't see why you would need to loosen it or try to wrench on the die to remove it. If you tighten the lock ring when it's torqued in the press with the die during setup, it's a major PITA to get out, which is why I suggested cracking the lock ring loose from the press to do the final tightening on the lock ring clamp screw, then torquing back into the press for sizing. If that makes sense.
*edit* - Also edited my previous response for clarification.
