8. You lifted your head
Lifting your head off the stock, whether from a flinch or simply from an urge to get a better view of the turkey falling over, invariably sends your shot high. Most turkeys, I would guess, are missed over the top. Having made such a miss once (well, maybe a couple of times) my mantra when a turkey approaches is: "Kill him through the gun." This is another clay target shooting phrase that means "keep your head down all the way through the shot and after."
