You have on one hand, guys who are happy with pie plate groups at twenty yards, talking about hitting a turkey in the head; a head that is in constant motion. Here's why I don't like that: Even the Gobbler Guillotine, and other such head, is turning with the arrow as it flies; what happens if it is vertical and just a bit off line(?). You can take the beak right off a turkey, or damage it without killing it. The luck ratio isn't with you on where that head will be as the arrow arrives, probably 50/50 at best. To me that is taking a chance that isn't acceptable. It's the turkey that realizes the consequences, not us, so that is too chancy for my liking. I'll take a broadhead to the chest cavity.
