It isn't a great feat to get full penetration on broadside deer, but what about quartering-away?
Barnes TSX
Nosler Accubond
Hornady AMAX
Again we see the characteristic deep, but relatively narrow path from the Barnes which easily achieves full penetration and exits. The Accubond has a wider path while still exiting most times. The AMAX may or may not exit but as shown will tear and disrupt considerably more along the way.
