Yep Capt, I figured you were just kiddin.
The Bullets I found in those Boars were nicely mushroomed and all there but the shield acted like a Kevlar vest and absorbed all the energy while stopping penetration.
One point that I feel is noteworthy is that the Broadhead had penetrated just as far as the bullets. Apparently the arrow must have eventually come unscrewwed from the broadhead cause it wasn't there, just the broadhead with the threads. That must have been quite painfull with every step to have those razor sharp blades stuck in there.
