Turkeys are amazingly hard to kill sometimes with a body shot. I lost two birds last spring hit pretty well with NAP Spitfires. A buddy of mine said the secret was to keep the head in the bird - either by shooting a 40 lb bow or by using some sort of penetration control device. For me, the latter worked well. I used the ASP washer between a 75 Muzzy and the insert. The Grasshopper washer also works well. Very difficult for the bird to run or fly with a broadhead stuck in him.
