It seems more and more of this is showing up at the gun auction sites. Its almost like some of the people selling could care less about a bad report on them. They usually answer with some Blah Blah come back of how they tried to make it all right with the buyer, and he refused to cooperate, and they are shocked he would have gave them a bad report.
Well you could shoot the rifle and see how well it does. Pitting near the bore is not the end of the world. I would shoot it and see how it does.
