When you're stressing something that's a 100+ years old It's just a matter of when.... I thought ferrous alloys didn't have a fatigue limit, doesn't that apply to damascus as well? https://en.wikipedia.org/wiki/Fatigue_limit

Should have qualified with not an engineer or metallurgist before I bite off more than I can chew. Genuine question.

Homeless joss, if the load steel is subjected to is 40% of the UTS of that steel, then there is no fatigue limit.

As mentioned previously here is a link to a 2011 thread on Shotgun World that has a tremendous amount of solid information about Damascus barrels. Worth long read. This link picks up well into the discussion. If you're really into the subject go back and begin at page one. http://www.shotgunworld.com/bbs/viewtopic.php?f=13&t=259371&start=40

Does anyone have a copy of the sherman bell article or articles in which he done those proof tests ? I don't have copies, but I have the original printings in the DGJ. I'm sure many of us do. Wouldn't be surprised if you could still order he back issues from them. SRH Which issues were the articles in do you happen to know stan ? Drew beat me to it, bonny. Thanks Rev. Been busy today. SRH

Maybe I'm just a simpleton, but one question begs to be answered, IMO. If damascus barrels were so all fired dangerous, why wouldn't the proof houses refuse to prove them? They could just simply say that they do not approve of anyone shooting them, so will not accept them for proof testing. Yet, they don't.
Duh?

Thank you Joe, an interesting article, especially on that site, i thought "the big i am" would have appeared and scuppered the thread, or the usual lot of people with the " my brothers wifes uncles best friends next door neighbour told me about damascus barrels and they're weapons of mass destruction" crap. Sherman Bell certainly put up and shut up, did the work and didn't rely on heresay and myth.

And in the end Sherman Bell only proved what the guns he tested did...

A proof house is different than an American strapping an old gun to a tire and just seeing if it blows.....I'm sure some vintage guns fail proof and some they refuse to proof. Documented fact is some failed when they were sent for proof a 100 years ago. When it comes to vintage guns damascus or fluid steel I don't think there's a blanket statement as to which are safe and which are unsafe.
