That DD buck is a dandy Ryan!
DK for sure about the other deer being the same but I'm leaning more toward it is the same. I've seen beams and racks change, either flip flop tines,drops come or go and bucks from 8's to 10's then back to an 8. Seen forks go from one side to the other as well as drop tines. There's enough of similarities on the right sides to make you wonder as they look very close but I think the deers face looks very similar as well. Both have a long snout TOO.
I'm not saying 100% the same but I'm prolly 75%.
