Back to the original question posted by Mojo. A couple of years ago I had a buck chasing a doe right past my stand. I called to him several times to try and get him to stop for a shot but he totally ignored me completely focused on following the doe. Finally found an opening and fired. He reared up on his hind legs ran about 30 yards and stopped trying to figure out where the doe had run off to. My second shot dropped him in his tracks. When I went up to him I only found the second shot. I back tracked to where he had been when I shot the first time and found a branch had deflected the bullet only showering him with bullet and wood fragments. Still, he was so focused on staying with the doe that he completely disregarded being shot at.
When the bucks are letting the little head do the thinking for the big head nothing else matters. I'd definitely go back to the spot and give it a shot just be very careful moving into your stand.
