Wilkes,
I have not shot the 100 Game King at deer but I have a buddy that has used it on well over a hundred deer - he swears by it. He says that if you hit ribs it will exit and they will run 30-50 yars (like most lung hits) but if you hit shoulder they will drop and it will not exit. I hunt really, really thick terrain and need an exit if they run so I have not shot the Sierra's.
