mjbgalt,
Actually, some of that "anal" stuff does make a difference, but the rifle has to be good enough to see it. Yes, in a SAAMI chambered factory barrel, it's the classic case of "putting lipstick on a pig" But done within the proper context, it shows results. Enter a serious bench rest match sometime and see where those 1/2" groups get you. (hint - those guys "actually shoot" their rifles too, and they know what works, and why)
