Although I've shot Zwickeys pretty exclusively since the 80s, I can't tell you how many heads I've shot animals with out of the same set up.... from 175 to 225 grains. Same bow, same arrow, head of my choice. No issues.
Zwickey, Wensel Woodsman, VPA, Tusker, Ace, Bonehead, Battle Axe, Magnus, Badger, Steel Force, Silver Original XL. Those are the ones off hand that I can't think of, but all are documented here on Tradgang. Also, some nasty custom heads a friend of mine and I made for pheasants....
