So, Grouse, you've never been in a situation where you have seconds to make a choice to shoot or not shoot? I find that hard to believe. Hunting can be a game of patience where you get a very quick opportunity to get your animal or not. I had a very brief window to make my shot on the buck I took last year. Had I hesitated, or not used the proper caution as he was walking by me, I would have not gotten my buck when I did. He would have been gone.
Stand hunting like I do, is like ending up in a bad situation where a BG comes into a place with multiple people. You have to not only be able to make the shot, you have to hide your armed presence long enough to be able to position yourself to make the shot. Tactics. Hunting helps build some of the fundamentals needed for defending yourself.
Apparently you don't bird hunt. There, it's all about making fast accurate shots. Same thing if you do any trap shooting.
Your comparison of hunting to self defense isn't all that accurate in many cases.
