Out west I've killed some animals at some distances in the wide open plains. Won't throw out any numbers as I really don't want the Ethics evanglists preaching to me.
Ehtical shots require consideration of a lot of variables, and only one is the distance. Many unethical shots are taken every year at less than 30 yards.
If I take a shot I have all the confidence in the world that arrow will find it's mark or Iwon't let it go.
