The wife and I enjoy going to Antique malls and this morning while in one I found a 12 guage David Pedersoli double barrel shotgun. The outside of the gun was rust free. Some scratches on the stock-which is to be expected. Overall the outside of the gun looked like you would expect from an older gun.

But here's where you guys come in: I didn't bring my bore light with me as I wasn't anticipating needing it so I couldn't see the entire barrel. I did run the ramrod down both barrels and it didn't feel rough or gritty. What I thought was odd was the first inch or two was shiny silver and even kind of looked like it had grooves in it. Not like it was threaded for chokes as the "threads" were no where near that deep. You could feel them more than see them. Do you think it could have been machined? If so, do you think that could weaken the barrel to the point of making it unsafe?

Additionally, I have never owned or shot a shotgun ML so I'm new to this side. Should the barrel thickness be in teh same range as rifled barrels. The thickness of hte steel on these barrels were no thicker than the ones on my modern shotguns.

Thanks in advance for the help.
