RE: Stop him first or not?
I don't care if hes a foot or a mile, I'm stopping him, or at least waiting for him to stop on his own.
I'll take my chances with jump. I cannot help what the deer is going to do, but I can help when I do or do not release that arrow. I don't have any way of practicing moving shots, nay have I ever taken one. So for me.... I'd rather have a good solid shot, and a still target, than a so-so shot at a moving one.
Not to mention that every deer I have ever had react to my shot (which has only been about 5 of the near 50 I have taken) has been calm and relaxed, and just stopped on their own. One was feeding.... got spined.
When I stop a deer, I make a quick sucking noise like a squirrel barking... I'm usually letting go as soon as the deer stops.
