Somebody has to say it. This is much ado about nothing. I can’t count the times I’ve had to wring a neck or cut a throat, of birds or game that had been just crippled. Not only is it ethical and legal, it’s the moral thing to do, you shot it, finish the job.
If you don’t have the stomach for it, don’t hunt, but a little blood on your hands won’t hurt you. You don’t have to dispatch wounded critters with a gun shot, carry a knife. A hunting knife, not one you use to clean fingernails with. Don’t have a knife? Crippled small game can be readily killed by breaking their neck. You’ve got hands, haven’t you?
Wounded large game, deer, bear, hogs, etc. might rate another shot, depending on the circumstances. But, I can’t get over the thought of Bubba the Dove hunter pumping a 12 gauge round into a 4 ounce wounded creature flopping around on the ground. Pick it up, wring it’s neck, stuff it in game vest.
