Scope nose, or scope eye, comes from getting to short an eye relief scope or chokeing up on the stock trying to get better eye relief. Moral of that is know the rifle before you pull the trigger. I had an ex BIL who did that with a 243 Sako becuase he choked up on the stock to much, what is even funnier is a guy who "knows all about handguns, and how to shoot them" then splits his forehead with the front sight on a 44 Mag because he was limp wristing.
