Heh... oops
Well, I learned that the hard way. It looks like whoever owned it before I did allowed a big screw that holds the barrel in place and also doubles to secure the stock to the action, to rust. It broke off inside. Luckily for me however, it broke off in such a way that still keeps the barrel in place. So that's not going anywhere. And that's where I called it quits and came to the same conclusion you advised. So thanks for that, now I don't feel like too much of a failure. Better not to screw around with it.
