whitetail deer circulatory system

I learned where to shoot a deer by studying biology. Today you can use the same computer you use to get on this site, by keying in - "whitetail deer circulatory system". Study the sites. Some, or a couple, will be better to most. You can save the better ones for future reference.

It's not just a question of being an accurate shooter. It knowing where to shoot, biologically. After that experience will take in. But you won't wonder why the deer dropped on the spot with a shot from a firearm, or only didn't go hundreds of yards after an arrow shot.
