To me there is a difference between the meaning of an ethical shot and a high percentage shot. Ethical shot to me is any humane killing shot that you feel without a doubt you can make time after time. High percentage is any humane killing shot that most hunters can make time after time. I am not turning down a humane killing shot that I know I can make on a daily basis just because someone else can't and doesn't believe it is an ethical shot. Will you ever miss on a lower percentage shot that you would normally make? Sure but I have also miss a couple of times on high percentage shots too. Ethical is staying within your personal limitations for making a clean humane shot.
