Barrels received a clean bill of health. Some oddities though. The left and right barrel have different bore diameters. Oddly enough they don't equate to a difference in choke which seemed robust for being cut. Measured around 15-18 thou. constriction. MBWT came in pretty stout just ahead of the chambers at around 100 thou. and the lowest we found was around 31 thou. near the ends.
Looks like I am going to have to find some 10 gauge shells..........
