#3 but 6 shot is definately awful light to be thinking about shooting a turkey around 30+ yards....... I patterned my winchester 1300 with a .665 choke and nitro magnum turkey #4's and had REMARKABLE patterns if you are intent on shooting sixes or fives i would stronlgy recommend giving the high density shot a try such as winchester supreme elite or actual hevi shot. . . . . you will spend roughly three times as much but i'd say increase your effectivenessat least three times as much because wounding animals should be avoided at all costs
