I just got a .40 s&w sub 2000. I plan to take it deer hunting. You say a fourty will not humanely take a deer down? That's wrong, I do not shoot over 50 yards where I am. It's not illegal either. On private land you can use anything including .22. I know just because you can use it doesn't mean it's right. But I feel extremely comfortable taking a shot at this distance. My question is what is the best hunting round for .40?
