Proofing a barrel

[jerrywh]

Black powder proof loads are published so are the procedures. That is what I fallow. I would not call that a redneck tire test. I am an experienced gun maker with way over 50 years of experience. Your opinion is just that and that Is all. My guns are proof tested by me and a witness according to published and time honored standards for the sake of my customers and myself.
Some of them sell for more than 40 or 50 good guns. I am booked up for life. The opinion of some attorney doesn't matter one dot.
Feel free to continue the discussion on your.
own.

You follow whose published standards, for definitive proof or provisional proof? The standards used in Birmingham, Bescia, Spain or one of the German Beschussamts. Since there are so many varied standards used.

Your test may attempt to follow some standard, but there is no independent test . I have read horror stories of US made muzzle loaders blowing up at European proof houses

I'd like to see some of that.
If it where common that American barrels fail in proof houses in any way I'm pretty sure we involved in this hobby would know of those sources and be avoiding those barrels that have failed.
I mean if American barrels fail with any kind of regularity, why wouldn't we be purchasing reliable European barrels?
There wouldn't be a single supplier offering barrels that fail, :idunno:

Yeah. I bought one of those also. Then machined it and lined it and Then I proofed it. No problem
Still have it. 50 cal. swamped.

Mine is a 17 1/2 ga. smoothie.
You lined yours. Would you have shot it without the liner?
BTW mine is for a fowler whose build has been "in progress" for twelve years. (long story, don't ask)

I would have shot it without a liner if it were a smooth bore after testing it. I intended to make a high art French rifle out of it on the order of a Boutet and wanted at least a 54 cal. I sent it to a known barrel maker to be bored and rifles for 54 cal. or larger. The barrel maker disregarded my order and made it a 45 caliber. I think he was afraid of liability. For that I have never made a rifle from it. I will probably re sleeve it and use it later if I live long enough.
