This didn't happen to me but I was sitting right there. My brother was using my mossberg tactical turkey two years ago on a quick hunt by our house. He ran home and met me out at the spot about 45 minutes before quitting time. We got set up and had a gobbler hammering away immediately. In all of the excitement he never extended the stock. He shot TWICE and both times the scope smashed him in the forehead. He started bleeding out his nose and through the gash on his head. Turns out he fractured his skull and smashed his sinus cavity. They cut him open, cleaned out all of the bone particles and implanted a titanium plate and 12 screws.
