This thread proves that terminal performance is equal or greater than a lot of those other calibers with the right bullet choice and at the right velocity.

Not to mention the countless things that can go wrong with a bow after that arrow is released...and you think people practice with a bow enough to be effective, or that they don't take shots they shouldn't? It is the responsibility of the hunter to take effective and ethical shots at game, and even more importantly to know their own limitations. Let's keep the argument focused on these reasonable and ethical hunters...because the second you start talking about unethical shots beyond one's limitations with a rifle, the same exact thing can be said about sticks and strings.
