Those shots would be fine, although, I specifically tell my hunters not to take anything, but a broadside shot, in the excitment of the moment, its often hard for them to tell or wait for the perfect shot. The way the ribs are arranged, its better to not take a shot from a forward angle. The top photo, if I was to take that shot, I would shoot just forward of the red dot, say three inches, but right at that exact same level. The second one, nearly right on the dot, but a couple inches farther forward wouldn't hurt. That drawing at the bottom, I would say is the ugliest pic of a "water buffalo, I have ever seen, it looks like some sort of weird buff cattle hybrid! The vitals and bone structure aren't way far off, but the lungs on a buff aren't nearly that big and it dosn't really give you an idea what you are facing with the ribs.
