The only series of events that could convince me that it was a simple mistake would be this.
-A solid pilot reamer.
-Small lathe that requires chambering in a steady rest.
-Put the chamber end in the chuck, live center in the muzzle. Turn the muzzle end so that it is concentric with the bore.
-Put the turned muzzle in the chuck, live center in chamber end. Turn enough OD for the Steady rest to ride.
-Now both ends of the barrel are concentric with the bore.
-Swap barrel around. Chamber end in the lathe, muzzle in the steady rest.
-Do all of your crowning and muzzle brake
-Swap barrel around. Muzzle end in the lathe, chamber in the steady rest.
-Do all of your chamber side machining and chambering.
The simple mistake that this method wouldn't catch would be checking the bore diameter.
It's a method that would be considered barbaric by any precision minded smith, but would probably be adequate for most average joe hunting rifles.
