For 1 you made a shot at a bad angle. If he was facing you, you don' t have a shot. 2 he had become spooky, and thats also a time for disaster. You seem to feel you could' ve made that shot work. But your results show different. So now all you have it coyote meat in the woods. Why risk such a shot, it' s very low percentage. I hope you learned a lesson, and think twice about it next time. A single lung shot chance simply means he still has 1 lung to live and breath on. Deer can go an awful long ways on a 1 lung hit, they are ALWAYS low percentage, risky shots period.
