Agree with the others. Best that you did not take the shot. Good luck getting him.

You definitely did the right thing. I' ll relate an experiance earlier this year. Had about a 130' s class buck come by my stand on 3 consecutive hunts (so most likely he will return). I made a bad shot on him and was close to being sick over it. I went in to a depression for about a month. It was bad, my fiance was getting annoyed and i felt horrible. The deer lived and 2 weeks later got hit by a car but I felt horrible at having wounded him. And that was a 20 yd broadside shot that I messed up. Imagine a shot that wasn' t perfect, how you could have messed it up.

Good luck, you' ll get him.
