If you talking about #7 Hevi-shot like what is used in Nitro 4X5X7 triplex loads then it works great! I wouldn`t use just #7 lead for turkeys, it just doesn`t have enough energy unless your going to keep your shooting distances very close. The Nitro loads use alot of #7 Hevi-shot (about half the pellets are #7s) and those loads a devastating on turkeys.
