Mike Moss, I am always looking into barrels. I get a lot of rifles in with the complaint being a loss of accuracy. Usually, a thorough cleaning makes a marked improvement. I always look at the muzzle because that is the last place the copper fouling is removed. If the copper fouling is gone, I am already looking at the next potential problem, the crown. If the crown is good (not just okay), it is time to take the barreled action out of the stock and look at the bedding marks in the barrel channel and rub marks on the barrel. But that is another story.
