I know this an old post but If you speak to Todd Hodnet on the subject he likes to leave his barrels dirty- only cleans the carbon and leaves as much of the copper as possible. The copper helps lubricate the barrel. Thus giving you longer barrel life. Carbon is what pits your barrel anyway. Unless you have copper coming out the end of the barrel he won't remove it. He addresses it in "Art of the Precision Rifle" from MagPul.
He says that he shoots 338s extensively in his classes and gets over 3000 rounds.
Most hunters like light fast moving bullets and they are harder on your barrel than heavy, slower bullets. The biggest factor is obviously what you shoot and how you shoot it.
