I went and shot my rifles the other day and notice my 338 point of zero had changed. So I got to thinking about it today and decided to look at the rifle and check the rings to make sure they were still tight. So when I check them the rear talley ring is loose. So I figure I will take off the scope and put more thread locker on the screws. Well when I go to remove the screw it is free spinning and not coming out. Turns out the screw was broken. So I soak it in Kroil and drill enough of to use a broken screw extractor. Well that went to hell in a hand basket be abuse the extractor broke off in the screw which is completely inside the reciever. So now I guess I get to go spend some money getting it fixed and hope he doesn't have to enlarge the hole when he is finished. Damn some days!!
