Re: Headspacing for 7mm stw?
Are you asking about re-chambering a 7mm Rem. Mag, to 7mm STW? If this is the case, I would set the barrel back at least a half a turn. When any re-chambering is done the end result would not to have any 'shadows' of the old chamber left in the new chamber. By setting back you would be cutting with all the STW reamer. You didn't mention the maker of this rifle. really need more info for a detailed answer. There's no way around not having a set of gages, IMHO.
