This is the exit of a 125 Spitfire from last years best buck. I also whacked a doe with a shockwave and both were dead within 40 yards. Neither arrow passed all the way through and exited the animal but both went through both sides. I'm sure the energy is absorbed when opening and slows the arrow to a stop. I got a bit of shoulder on the doe. Both wrecked my arrows. Both tasted very good.
