A gobbler on a wooded ridge will fly down from a roost and walk the ridge. Always try to be on the same level or slightly above the bird. Greg Abbas prefers a sand hill crane call because these birds are native to the state. Buy several turkey targets, and fire at the junction of the head and neck. Count pellet holes in the head and neck of each target to determine which shot size is best for the shotgun.
Many savvy hunters mount a scope on their shotgun for more precise aiming.
Never shoot at a turkey's body.
