The vitals of a turkey are about the size of an orange. But they are hidden behind something the size of a feather pillow that regularly changes size, shape, and position. And they don't really leave a blood trail when they run off. I've bow hunted since I was 12 and turkey hunted since I was 14. I'm not comfortable trying to shoot one with a bow. The benefit of doing it is low and the risk of wound/loss is very high. For a kid with no turkey hunting experience . . . I wouldn't. Lots of good low-recoil loads for a shotgun that will kill turkeys as far as a cross bow.
