Was talking to my bro yest. about my Rem 700 30-06 and he told me he had talked to his gunsmith who had returned 4 700s in the past 3 weeks. He mentioned something about putting a go or no-go gauge in the action... Can anyone tell me what this is about. To the best of my knowledge, the gunsmith was saying that some of the 700s have chambers too big and when you shoot, it can bea potentially hazardous problem. Anyone got more info on this?
