Not having done this or seeing it done, I'm really surprised by the amount of barrel metal removed. I've cleaned up and prepared factory stock barrels for muzzle loaders and never had to remove near that much metal. 1/32" is around .040...that is a serious amount of barrel stock. I look for minimum wall thickness of around .030 to .035 and well accepted wall thickness ahead of the chambers. Those barrels must have had serious external pitting or other damage to need that amount of striking. Any idea as to what the wall thickness measures after the refinish? I do not consider anything under .025 even on a very special gun. Just curious and looking for more information.
