I have a friend who did something similar. I wasn't present and it was many years ago but he told me the story. He saw a buck at a distance in Pennsylvania woods (Probably 40 years ago). He took a shot. Upon shooting (30-06 I think) he saw what he thought was the buck running away. He shot again and it dropped. When he got on site he had killed 2 bucks. You are only allowed one buck per year in PA.
