Just curious if anyone has experienced ring bulging in damascus barrels using bismuth. I've only used ITX thus far, but being harder than bismuth, it has ring bulged a damascus barrel I had. Was just curious if bismuth would do the same thing, being that it's softer. It's too bad, because ITX is deadly stuff. If I have to use steel barrels for ducks, I will, but I love shooting my damascus guns.
