[QUOTE="geargrinder, post: 356303, member: 6705"] 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 machining -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. [/QUOTE]
