Good deal I'm in Peoria ill see what I can come up with and meet up if possibleI live out by the White Tank mountain area in the west valley if you are in AZ. I can help with some basic inspections, have Cerrosafe, micrometers and a lot of experience on 7 mags. Would be willing to take a look at it if it's convenient for you. Something is way off somewhere. Don't trust those calipers in the bore to get an accurate measurement, just rough numbers.
