Non-destructive testing of damascus barrels Archived Message Posted by Drew Hause on March 17, 2015, 6:56 pm, in reply to "Re: Shooting Damascus safely" There are no industrial standards for MPI of a pattern welded barrel, but a few gunsmiths and metal testing laboratories have tested damascus and twist barrels. I am not aware of anyone with expertise in radiography, and the interpretation is quite difficult. Please let us know who is doing the testing and the results of the evaluation.
