First pattern your gun, try to use a turkey head target. Many companies make them, or you can download one from
www.remington.com . Then adjust your sights or sight picture to try to put the head in the center of the tightest portion. I liked to aim at the middle of the neck. That cut down how many pellets I put into the breast area, annd centered the skull in the pellet swarm. Try to not shoot if the bird is tucked in a strut. This decreases your target. Wait till it extends it' s neck if possible.
