At 9" the bores are .717 diameter and the barrel flats are marked a 13. I fired three 2 1/2" shells through each barrel remotely and then inspected them carefully after bead blasting and I see no faults in the barrels. The gun only has black powder proofs, it has been in Canada for much of the last part of it's life we have no proof houses here. I would be interested to know how to measure the thicknesses you spoke about, I understand how to measure bore diameter and have the means to do so. I have only measured it at 9".
