RE: no scope or scope
I'll believe he made the shot, I agree that it's idiotic for people to think that a guy has to have a glass to shoot good groups, or make good shots. It all depends on how well you shoot the rifle/scatter/pistol/revolver. I have a Marlin .22lr that has no sights at all (made for a scope), but I can group it to 2" at 75yrds, which is pretty impressive for any old, factory .22. I watched a cousin of mine, while we were drive hunting, scare up a buck, draw his .357 mag, and make a double lung & heart shot at 60yrds on a running buck.
Screw the 10 ring, keep them in the zero!!!
