Bree243 I have hunted turkeys with my crossbow for many years and have also given advice to many others as well.

The most important aspect is to use a setup (arrow & head) that you are comfortable and have confidence with (accuracy). If your deer (or other hunting) setup is good and your confidence is great with it, then use it. You do not need different or special heads to hunt turkeys. The only thing I would advise that would be a little different is to add an arrow arrester of some kind. I and many others use an arrestor called Zwickey Scropio. These arrestor will slide on the arrow shaft to lessen the impact of a fast stopping arrow but will still keep the arrow from passing through. The non pass through will limit the ability of the bird from flying or running away. One tom that I took (150lb bow) was knocked sideways 3 yards from the arrow so they will still get all the KE from the arrow, just not the brusing of the meat as from the solid arrestor types. One other factor I found out with this arrestor is that it did not effect the point of impact at all.

Hope this helps.
