OK, I have a Savage 12 F/TR .308 which, for a variety of reasons, I think the barrel may be past it's best. Dwelling on this, I thought of the following. Savage barrels on this type of rifle seem fairly straightforward to change. OK so far. Barrels tend to lose their edge as a result of burns to the throat of the rifling. So, could a competent gun smith cut 2 or 3 inches off the rear of the barrel, re-thread and re-chamber it, then, of course, re-fit it? In theory, you should end up with a barrel that is much better than before, but much less expensive than a replacement. What do you think?
