Green scored the skull this weekend. Looks like it will come in at 21" or just shy depending on how much it shrinks. I'm pretty psyched, I knew he' was big but never guessed that big.  He was definitely on the decline because be was not a 300+ pound bear. Provably closer to 250. Front paw did measure 6 3/4" though. 
I'll keep you all posted on final score.
