I’m not asking because I think it’s hard to do. I’m asking because I’m completely new to this and don’t have anything in hand yet. I won’t be changing except for when needed like going from sizing to seating. What I don’t know is if the nut can be locked down so that it maintains the same setting when removed and later reinstalled? A couple of videos that I have seen shows the guy having to tighten the nut back down after reinstalling the die. I’m just imagining that there should be some way to lock the nut in position so that every time I swap dies they screw back in to the same depth every time without needing adjustments. It should be a repeatable process and it may be. I don’t know and that is why I’m asking.
