RE: Shot placement on animal A - a detailed look
My point was that if the anatomy is shown correctly, not as much of the vitals are covered. I would take this shot. I'm confident that I could place and arrow through at least one lung and the liver....possibly both lungs.
If it were an actual situation....I would wait for a better shot. This deer looks like it's walking or is about to move his right front leg forward. This will increase my good shot odds. He doesn't look spooked either.
In all actuallity, I'd probably fall apart and not be able to draw my bow on a deer of that caliber! That isn't exactly commonplace in PA.
