Well then, unless you have tags for every possibility, you should not be shooting! Taking shots at something you are not sure of is gambling. Except that when you walk up to your kill, and it's not what you hoped that it would be you can't take the bullet back! That's not too far removed from poaching!

Another peeve of mine is when someone starts a sentence with, "I normally wouldn't take a risky shot, but........"
If it's a "risky" shot that you'd "never" take on an average animal, why should you take it at a trophy!!!!!?????? Don't we owe the sport and the animal more respect than that!!!!!????
