Patrick,
But if it is over, why couldn't a competent machinist bump back the shoulder and the very end of the barrel to effectively shorten the chamber and move the bolt in by the same amount.
I realize I'm probably not using the correct terms for the 2 faces I'm referring to, but I think you probably know what I mean.
I never even thought of messing with it if it was under. I assumed that was the SOL scenario.
Not sure what the 'stupid' comment was about. The barrel was machined in the first place. If it was machined in a way that's sub-optimal, and it can be modified, why not? I'm not talking about doing it in a garage with a belt sander. This would not be for a general purpose gun either.
