I second the headshot/base of neck). If the turkey runs then your chances of finding it are slim. Turkey leave absolutely zero sign of being shot, other than a few feathers left behind. No blood, nothing. All you can do is watch where the sucker went. And go from there. When they're injured and hide in the bush they might as well be wearing an invisibility cloak... My first turkey was a thigh shot and he flew 80 yards and crashed at the edge of the bush. I gave him 45 minutes. I scanned the area I saw him crash at DOZENS of times, he was basically where I saw him land and I must've almost stepped on him a few times.
