"I have little doubt that the Preacher has been frantically searching for a rash of cracked Flues in order to prove me wrong."

Sorry William, but I have no emotional investment nor intellectual interest in cracked frame Flues, or your self-absorption and paranoia. I'm not stalking you.

I did once buy a nicely restocked with a BTFE and beautiful wood 10g Flues at a gun show for fun, only to find someone had hogged the chambers out to 3 1/2". This was long ago and before I had a wall thickness gauge, but I had read enough to know not to use the gun as it was, and didn't want to invest in custom full length 12g tubes. I sold it with full disclosure to a guy who wanted the stock. Interesting, no cracked frame and the gun was tight and on-face.

BTW: could you please address me by my name, and leave my calling and ministry out of it? Thank you.
