Great advice Miller, and I hope Neanderthal checks and double checks, or has a gunsmith do it for him. If he was really getting a chamber length of 3" to 3-3/32", it could mean that some fool opened up his chamber and possibly left the barrel walls dangerously thin at the point of highest pressure. A lot of bad things can happen in a guns 100 year existance, like reaming, honing, and polishing of barrels. Sometimes the result is so bad as to be immediately obvious. Other times it may look perfect, but leave you with a gun that should not be shot with any loads. Most garden variety Flues sell for less than $350.00 in my neck of the woods... not enough to risk losing an eye or fingers.
