I'm with bigduke6 on this one. The barrel may be just fine as is. I'd be more worried about the oil soaked coachwood coming apart at the seams under recoil. It's just a fact that it isn't the best gunstock wood in the world. I've seen so many forends that were just destroyed beyond economical repair and replacements are hard to find and expensive. I had one of my own crumble while shooting too many years ago.
