ive shot heavy shot alot for ducks but neverfor turkeys winchest 2-14 oz of 4s was all i use to shoot till they changed there wads used to kill birds at 50-60 yards all the time now i use federal 2-14 oz 4s with the flight control wads they put 15-18 pellets in the kill zone of a turkey target at 55 yards i wont shoot any other size shot but 4s if it wont pattern at 55 yrds i wont shoot it and its deadly on coyotes if you come across any while your out. and its alot cheaper.
