Have you ever tried shooting on a dart or video archery range? This practice does wonders for "shot timing" which is really the issue for most. You are concerned you will not be able to get the shot off in time once the animal is in range which raises anxiety. If you don't want to pay to shoot a few of the dart video archery ranges, you can mimic this by watching hunting videos with shot scenarios only and turning the sound off and practice drawing on these animals as they come in. Don't get caught up in the animal you're hunting either. The African game video sequences are excellent as most of them critters really move in and out quick. Yes, 3D shooting helps with range estimation but in my opinion, shot timing is what gets most people freaked out at the time an animal comes in. Also, don't look at the antlers! Finally, if you don't get breathing a little heavy and feel that tension a little bit, I wouldn't think its fun any more. That's the primal predator coming out of each of us. You can do that with any animal that suddenly becomes your target.
