If quarter-size groups were required to hunt deer, 95% of all hunters would have to stay home. You need to be proficient at the ranges you will shoot at game, say 3"-4" groups, nothing more. What this means is that you will not miss your intended point of aim by 1.5"-2". That is more than adequate for hunting deer. Where I hunt, I don't shoot deer at ranges past 150 yds, soit is really about the hunting and notabout shooting skills.

IMO, too many guysget too worked up about every last detail. They make it more like work than about enjoying the hunt. Keep things simple to start, and then add equipment, call, scents etc. as you feel you need it.

You will be a good hunter after a season or two if you pay attention to the wind and take the time to learn what deer are doing in your area. Don't just walk to your stand and leave when done. Sit your stand, then if you are not seeing deer, stillhunt the area using the wind to your advantage. Observe the sign that is there and re-set stands accordingly. Hunt in all conditions and adapt tactics to fit the conditions.

You may find that while you like stand hunting, you really like stillhunting better. Stillhunting keeps you in touch with where the deer are. Any good stillhunter can kill deer from stands, but not every good stand hunter can stillhunt.
