You got some interesting pictures. On the first one with the odd rack, does his left back leg look a little funny? It looks a little out of shape or crooked to me. He may have gotten injured and that could be the reason for the odd rack. Good pictures. Looks like you should be able to get a good buck this year.
I shot a deer with one misshaped rack and indeed as DH said the buck had a leg injury on the side opposite the odd shaped antler. I have read that a leg injury can cause antler oddities and often on the side opposite the weird antler.
