I practice regulary out to 60 yards and can keep most the arrows in a softball size maybe larger on some days. I do however know that the bottom of my sight ring is right at 80 yards so if he is within 80 yards I am going to try it. More than likely he would jump the string and since it will take the arrow a while to get there he would have moved. Heck I have had deer jump the string at 30 yards and it grazes right off thier back or slightly over it. He may just come up in time to hit it again.

Can not hurt to try and get another one in it IMO.
