Rocketman I hope you're still able to type when she blows.

jOe, some add meat and some spices to the threads. You are definitely on the
spice shelf! :-)

hJ - I'm a lot more worried about a lot of other stuff. Wiping out in a damascus barrel failure is way down my list of probabilities.

Gents,

Thank you for your support.
I do intend to study this problem. First I need to document myself about the type of study. I would like to get some meaning out of it. If there is no meaning, it's obviously useless.
I am out for an exam now, will get back home in a few days and start reading.
I will post back once I have some idea of what I want...can do...

Me too....I shoot mine weekly.

New to the forum, but am familiar with Damascus technique, and the proud owner of a George Barlow Coach Gun from the old days. After I bought it at auction, I did a bunch of research in Damascus metallurgy, and inspected the barrels - in pretty good shape for an old black powder gun, actually. I did buy and test with black powder 12 Gauge shells, and it passed the test. But I would never put a smokeless round in it under any circumstance. The pressure profile is different enough that the stress profile would be well outside what the gun was designed for, but the very nature of Damascus barrel construction means that each one is absolutely unique. Successfully shooting 1,000 of exactly the same gun make and model successfully is absolutely not statistically relevant with a one-off item like a Damascus barrel. Let me put it this way: if you had a jar of jelly beans on the coffee table and you knew one of the beans was poisoned, would you eat any? The nature of Damascus welding is such that a flaw within the steel, opened to the barrel by a corrosion pit, is a distinct possibility because of the unpredictability of galvanic corrosion rates in these hybrid metal barrels. The only possible way to know for sure the condition of a tube manufactured in this manner is by Magnaflux and x-ray - Magnaflux for surface flaws and x-ray for subsurface.

Welcome to the forum, George. You certainly aren't too bashful to offer opinions.

However, there are many holes in your argument that I am not willing to put forth the effort to address. But I will offer one quick question............why do you think damascus barrels are any more "unique" than fluid steel barrels? Individual fluid steel barrels rupture at times, too. If they weren't "unique" too, all would either blow up or none would.

That statement is flat ass incorrect.

Your decision to not use smokeless no matter the loading in your gun is fine by me.

At your level of knowledge it's the best thing for YOU.

I think "George" might be one of our long time forum instigators coming up with a new profile name, and who just recently happened to start a thread asking about black powder and velocity. What a coincidence.

Here's a very astute observation concerning a very dumb question about black powder loads from one of our most prolific anti-gun trolls. Leave it to Ed to dredge up a 10 year old thread and assume the name of an old studio wrestler:
