By no means am I an expert turkey archer, as I prefer to chase them using a gun with the mobility and run ‘n gun style that I like. That said, I’ve killed a handful of bow birds with each style of head, and I’m as perplexed as you are. Also, I think I’d add the massive expandables to a third “type” of turkey broadhead.
I’m also embarrassed to admit that I’ve mortally wounded AND lost a bird each with an expandable and guillotine. Both were shots that I felt were kill shots….arrow flew true, went where I thought it should go. Puzzled.
My first bow bird was actually a hen, from a tree stand while hunting deer. Never shot a regular head again, maybe that was my problem?
In theory, the guillotines or that style head is the way to go. You’ve got about 6″ north/south on a turkey’s head, 2″ left/right, and you’re shooting a 4″X”4 swath, meaning room for error from the center of your arrow shaft is nearly 2″ left/right and 5″ or so up/down. That target is much larger than a turkeys vitals, I’ll tell you that. However, the turkey’s head is more prone to sudden movement.
Also in theory, the guillotine style is supposed to kill them, or miss them. I can attest to a bad shot with the guillotines, the surface area of the head is so large that the whole deal bounces clean off the side of the bird. At the same time, I hit one a bit low on the neck 3 years ago that I trailed for almost 150 yards. Blood on the ground and all. Never found it, and I didn’t give up for hours and hours. My problem with the guillotines is that I never got that arrow to fly like it should. Too much dodginess in my setup.
So, I think if I take after them with a bow this year, I’ll be shooting massive expandables (Rockets) or the bullhead from Magnus. Haven’t decided yet.
Sorry for the novel, and I’m sure I created more questions than I solved problems, but that’s been my experience. I think a premium should be placed on what you can shoot the most consistently.
Good luck, and let us know what you figure out!
