unethical,,thats a term used alot,,
I think marginal,, or low rate of recovery,, or iffy,, or risky,,sometimes in the excitement of the moment we make a mistake,, and have no intention of being unethical ,, as you draw your bow the deer turns a bit toward you and its too late to stop the shot,,,
sometimes you take a shot that looks great, but the deer moves as the arrow is heading its way,,
then you are in the iffy area of the deer,, with all good intentions,,
thats when you really need to be patient with your tracking and keep positive,,
sometimes that shot hit an artery or liver or something and the outcome is postive,,or more positive than it looked,,
thats why you need to stack your odds taking the best closest shot you can, and that takes patience,,and some " shot control"
I think the more experienced you are , the easier it is to take your "Best Shot",,,, and pass on a maybe iffy one,,
even 20 yards is too far for me at a deer,, and I practiice out to 60,,, and have killed deer past 20,, but experience has taught me, the longer shot has a lower succes rate,,
