Killing and mounting is your call bud, no one else's opinion should matter. That is a stud of a deer and I would shoot it. Mounting for me is more of a money thing, I've shot 3 bucks that were mount worthy(in my opinion, some say all my bucks have been save 1).....only 1 is, other two Euro mounted.
Drop him Put it this way, if you dont drop him, he is going enough that if someone else gets the chance, they will. I vote to drop him....Good Luck.
Tyni put it right. You sit in the stand, you see the deer approach, whether or not you take the shot is not up to anyone else. And as far as mounting, look into your wallet and mind and decide.
