[QUOTE="Mikecr, post: 163360, member: 1521"] I think everyone agrees that an opening bore at the muzzle kills accuracy potential. It would be fantastic if someone with a 'Hummer' barrel could have it carefully examined in this regard. But I have never seen credible values for inside bore dimensions throughout a barrel's length. You'll get "consistant from end to end, with the muzzle end tightest". "Our barrels are super-Lupdy-Duper at .0001 from end to end". But that is not a measurement at all. That's comparative guessing with an air gauge type BS. I personally wish I knew of an instrument capable of actually measuring groove/bore dimensions. [/QUOTE]
