The Birmingham Proof Tests were published and listed best to worst.

Drew Hause has posted it here before I believe.

Best to worst is probably not appropriate; "worst" wasn't used
https://docs.google.com/document/d/1...EK8OtPYVA/edit

These experiments serve to show what a very large margin of strength there is in a good gun barrel, when ordinary charges are used. The (Damascus) barrels which gave way earliest...had withstood the strains of…about four times as great as the regulation proof; while the steel barrels (Siemens-Martin and English “Superior Barrel Steel”) were tested…with charges averaging nearly five times as much as the ordinary proof-charge.
Although the steel barrels showed the greater amount of endurance, the strength of the Damascus was so much in excess of all ordinary requirements that no fear need be felt of their giving way when the work is properly done.

Limited tensile strength testing of various pattern welded barrels show very little difference; about 55,000 psi for Crolle patterns.

We just look down the barrels in good sunlight and if we can't see daylight shinning in through the sides they're good to go.

I don't know, Paul. I have a little 16 gauge Lindner that shows daylight through the sides of both barrels, but hasn't blown up yet.

Please don't say Lindner. About 10 years ago I opened my mouth about one being in a local gun auction and a fellow who read my post bought it out from under me. I still think about that one.
