Re: Headspace question
Just "listening" in... It is my understanding that the belt is what the BM's head space off of, and that number is .000 to +.002. After that the shoulder is fire formed for the chamber and when you size it is neck only or a shoulder bump to somewhere around touching to - .002? That is the way I do it but after reading a few posts it sounds like some guys are only concerned with shoulder headspace.
