QDMer, like the other guys on this thread said, don't use a mechanical broadhead. I shot at an antelope at 25 yards with a rocket hammerhead broadhead and ended up watching my arrow fly a foot over his back. I looked at the hole in the screen and had two short slits on the sides and one long one on the top. Looked like the blade hooked and opened on me. I have tried some muzzy's when I was practicing and they flew pretty good. I think I would still limit my shot distance though.
