BarnesX.308,
What do you do when you (on the rare occassion) don't place your shot perfectly? Of course we all try to place our shots to harvest the bird in the most humane manner. However, when that shot doesn't quite do the job, carrying a miniature guillotine in your game vest gets a little heavy so the neck wringer is the next best thing. It's all in the name of not making the bird suffer.
