So, was the doe looking at you? I'm betting no, that would be a bad condition for a long shot, with an arrow. Nice picture!
That is, how do you know if you're going to hit it? What conditions are important ones?
I had heard, like Nut, don't shoot, at least a whitetail, at 40 yards. 39 could be ok, but 40??? One time I had a nice 8 pt looking at me broadside at 40 yards. I drew the bow and he was still watching me. I thought, he's asking for it, so, I released. He ducked, he leaned forward, then he turned around and was about 1/2 yard completely out of his previous position when the arrow went by. If he just ducked, I would have got him.
Anyway, I didn't wound him, and I learned. How fast are those bows where you shoot 60-70-80 yards, what conditions make it work? Those skinny carbon arrows, get more penetration than fat aluminum arrows, even shot at 15 lbs more pull, I think, based on hay bale observation.
