Gentlemen, once again thank you , I sent a nice old Jeffreys sxs out to be checked out , the rt barrel was honed .020" & the left to.030" , the smith felt .020" was to thin (6 inches from the muzzle) and .030" is minimum for saftey. The gun is just a "Farmer Gun " & not worth putting alot of money into , but I think it might just end up as a sometimes grouse gun with low preasure loads.
