If I can't shoot a Turkey facing away from me directly in the spine and break him down that's a good enough reason for me to shoot something else[8D]
WV The Guillotine and the Bullheads are great heads I'm sure, and their effectiveness is undisputable, but the accuracy range for me was very short. I tried several different arrow spine, material, and Fletching combinations and I would not trust them much past 15 yards. Inside that range I'd say they would be fine. I just didn't want that limit on myself.
