OK, like most people I have been told not to shoot damascus-barrelled shotguns unless they have been re-lined with modern steel inserts. But in some of the hunting threads I see that people are apparently doing so. In one case the fellow said it was relined, but in many other photos the guns do not appear to have had this treatment.
So, is the 'conventional wisdom' wrong? If it is safe to shoot some of these old guns, how does one go about testing the gun to determine if it's reasonably safe to use?
