Yeah, funny. Just don't hit the 8 or 9 ring. That would probably hurt worst than one in the 10 ring.
Several years ago when I shot my flinter a lot and my eyes were better I made a shot like that. I normally wouldn't take that shot and today I would never attempt it. But it was the last day of the season and my freezer was void of venison. I had a mature doe walking straight away from me at around 40 or 45 ydd, stop with her tail up. I set the front bead under the dark spot and squeezed off the shot. When the smoke cleared she was laying right there - stone dead. I never did find the entry hole on that deer. It must have been like getting a 50 cal suppository.
