So got my new scope today and in a rush to get the Talley rings loctited before work, I stripped the top thread of one of the holes on the rear of the action. It's preventing the rest of the screw from catching and twisting in. If I take the base off, I can thread the screw in no problem. The adjacent screw keeps the base rock solid but it'll ease my head if I have both screwed in. So what are my options? I was thinking either a longer screw or drilling the shelf down a little further so the screw catches.
