Having a muzzle brake being put on a rifle. I have the dims all figured out - do I need to re-check the shoulder datum and oal at the ogive once I get it back? It has iron sights and is bedded - I figure that it needs to be put back into the exact same spot for everything to be right. Just asking so that I know what I need to do when I get it back. Would I have to bump down the brass I have set for a slight crush fit if it is tightened down past where it is now? At least this is how I see it. Thanks for your help.
