Depends on how you look at it? If you think thats considered a humane shot then thats you business. Im not saying it cant be done, just giving my opinion. Ive shot deer in the neck but they wernt big bucks. I wouldnt risk losing a nice deer by shooting him in the chest because there is less room for error there than a broadside shot. Im gonna say a chest shot on a nice buck is AMATEUR cause thats what i think. hunting is about patience, if you dont have the patience to wait for the a good clean shot then thats you, and you will be spending the time that you could have spent waiting on a good shot on finding your deer!
