You use what to measure with?
Tape measure works for me. But seriously is it how Mid state stored their BBLs that caused the problem? I see on equipment list that Shilen BBLs win a lot of matches. I'm a varmint rifle own I shoot a dragon 6x284 sounds like that LW BBL might do me some good. Problem I have a Hart varmint contour BBL now my gunsmith has run a bore scope down it and says there is significant throat erosion ! But the rifle still delivers under 1/2MOA at 100. I mostly shot max loads and about 700 rnds through BBL so far. So just how bad is throat erosion? Sounds like my gun smith wants some work early?
