Should the size of the antlers effect how much effort you put into finding a animal or the way you would track one? In my opinion If you make a iffy shot you should give them a couple hours before tracking. If you jump him after a couple hours you your best bet is to go back to camp and be on the blood trail at sun up. I have learned from experience if you jump them more than once or twice your odds of finding them go way down. After they have bedded for several hours you will not find any blood when they get up and run. Then your stuck tracking. The hunter should of been able to tell if the bull was dead before shooting light or not. If it was freshly killed it's fair game. (don't think I'd help pack it out though) If it was stiffening up already I think it is BS that they took the bull and I would have probably gotten physical.
The hunter should of kept his mouth shut about shooting the big bull until he found him
