Misses happen I guess, depending on low light and small branches and such, but I would much rather, and have, let a deer walk by and not shoot rather than take a shot and "hope" I hit it. No shot is better than a missed shot because a missed shot is just a few inches away from a bad shot that could wound the deer without killing it. Personally, if I'm not 100% sure the arrow is going to hit the kill zone, barring mechanical failure, I don't take it.

And this is my first post as I just found this site today. Hi all!
