Please understand this is my personal opinion based upon my experience working for a metals company and this opinion is NOT shared by others on this forum:
A obvious problem like a pinhole is a symptom of perhaps far worse widespread problems and the closer these problems are to the breech area the more potentially dangerous they are to the shooter. Damascus barrel shotguns all have voids in the metal as this was an inherent result of the manufacturering process. The voids can only get worse due to internal rusting over the past 100 or so years.
I do not have any personal axe to grind here and it still a free Country and if anyone wants to take the chance and use these guns no one least of all I will stand in their way.
