Elmer Keith stated He killed a running buck BEYOND 600 yds with his 44 mag pistol! Never could quite believe that one.
Having made a handful of luck shots in my days, thats what this is if it happened.
IIRC that buck was wounded.
But whats interesting, he had the knowledge of appx drop at that range and had shot enough to get slugs in the area.
Most folks, me included would have no idea of the drop of a 44 at 600ish steps/yards.
