Bumped for Corbett.
I see a deleted post from you, was this some half-assed attempt at a response to my post.
I don't know how to dumb this down for you any more than I have. Even the picture Steve Galbrath posted for you didn't seem to help. It's impossible to say precisely what the orientation of the bullet was at any given instant but we can make reasonable estimates. The smaller hole in the front of JBC's jacket suggests it had continued to tumble after entering his back in a near perpendicular orientation. Whether it had tumbled 150, 180, 210 degrees or somewhere in between is impossible to say. What we do know is the base was flattened from the side. That indicates the base received the brunt of the blow when the bullet struck bone which is evidence the bullet was tumbling. Further evidence is that lead fragments were deposited in JBC's wrist and thigh. That came from the lead core which was only exposed at the bottom of the bullet.
