Got a vert line on my forehead of scope bite. 308 bolt gun did the deed. Buddy has a mark from a 50BMG that bit him from 8" away. Worse one is buddy of mine. We were shooting a muzzle loader with 100 gr of pellets and power belts. He wanted to try it and we put 150gr of pellets and a high pressure sabot instead. He crowded the scope and left skin inside the eye piece and blood running down his face. He shoots a 300WM, so thought he would know better. We thought it was sorta funny as he was an a-hole; but couldn't tell him what we had done. Needless to say he won't shoot a muzzle loader.
