I'm not a metallurgist and I don't play one on TV. What does rust do to steel? It weakens it. As more of the metal becomes unprotected then the rust will spread.

I have no idea how they make or get their barrels, but I just can't see that by doing it correctly it would add more cost or be time consuming. When you take this into consideration along with everything else that isn't done, one can see who truly makes a quality weapon and who doesn't.
