I fuss over those adjustments, but when I get them right, I leave them set permanently and it's a one-time hassle. One thing to beware of in acquiring brass is that some brands of brass will drive you nuts. AMERC is not usable and should be discarded, S&B can be a bit of a hassle to seat the primers, but I've never thrown one out because it was unusable. I prefer Winchester or Starline brass.
