I removed the bolt from my receiver and adjusted the bolt to the fired position. I then wrapped the bolt up in some soft cloths and gently put it in my vice. I can't seem to get the bolt on the back of the bolt handle to budge at all! I have used several 1/4 inch hex wrenches including one in a socket driver. The only thing I haven't tried to loosen it with is a breaker bar. I am sure I would be putting way too much force on the bolt if I was to use a breaker bar on it. I called Savage and they said they can't tell me anything about it because it isn't standard disassembly. Any help is appreciated. Thanks!
