It's simple physics. Therefore, any round that is carrying 600 ft-lbs of energy and fails to penetrate a target at all must transfer all 600 ft-lbs to the target. That is more than enough energy to knock a bowling pin over!
Energy doesn't knock things over. You could shoot a bowling pin with 600 ft-lbs of energy from a laser beam and just burn a hole though it without moving it at all.
Momentum knocks things over, but doesn't necessarily hurt them. Thus the superiority of the M1 carbine round over a thrown rock with the same momentum
