I use the 2&5/8 ounce " economy" hevi shot load from Nitro in my 3.5" 12 gauge Browning BPS. This load is amazing. It performs just as well on turkeys as it does on paper. The Nitro ammo patterened better at 60 yards than did the best " factory" load at 40 yards. Before anyone says anything I would never take a shot that far and I realize that at that distance you most likely do not have enough energy to take out a turkey. Buy a 10 pack of the stuff and pattern it beside your best shooting ammo and see what happens. Hey its only money!!!!LOL
