Ken, I agree with all you said, but in this situation, he is clearly trying to save some money, and I don't think he's gonna spring for a bore gauge. If the method I proposed, was repeated for every inch of the bore, he could get close to the what a bore gauge would show. I know if I had a questionable barrel, I would check the entire length of the bore.
