That's impressive. Just the cost in ammo is astounding.
While I'm no metallurgist, if the steel under the chrome lining is harder, I would imagine that can only increase barrel life. How much is the million dollar question.
EDIT: I also wonder if gain twist rifling would add to barrel life due to reduced engraving forces required at the throat.
