I slipped and fell and broke a scope one time. Eyepiece was at an approx. 15 degree angle to the rest of the scope.
When I fell from the stand a few years ago, I broke the stock on my 30-30, but the scope was ok. I after I repaired the stock I figured the scope needed to be zeroed, but I was wrong. The scope was still shooting 2" high at a 100 yds.
