I started hunting with a bow 3 years ago and thinking about a turkey but I think the first one will be with the gun. Our fall turkey season runs with bow season for deer but haven't had a chance at one yet. I have read what xcal1ber has said also the first choice is a head shot, (not for me) and the next I read was where the leg joins the body, they claim a turkey needs his legs to take flight and that also would be in the vitals. The wing would do the same. Good luck to you!!!!
What works for me may not work for you and what works today may not work tomorrow
