I've killed a ton of animals with sub 250fps bows and beyond 40 with that set up. It's not the speed that kills them rather the understanding the animal and what his language is telling you. If that deer is skittish at 30yds and you're shooting 400fps you'll still have a bad hit, their muscle twitch is just too fast.
I currently shoot 280fps and have shot animals out to 60yds.
