Those variables also work in a hunters favor and if they were right a shot at any distance would be a good one for me providing I could make it. As far as an animal moving, most stand stone still for great periods of time checking the enviroment. They never hear the shot with the wind and enviromental noises right. Shot 2 last year using those "variables", one with the added stink of some rotting roles of wheat straw (thank you very much mister farmer).

I also use good optics to see the variables that work for and against me.And there's no substitute for good preseason scouting to determine the kinds of shots required to be sucsessful.

Variables? Sure but there not all negitive.
