Guess I'm behind the times as I still shoot Hevi 7's. Killed plenty of birds with the stuff and see no reason to switch up yet I guess. Maybe someday I'll give them a try. My T/C with an Indian Creek tube throws a great pattern out to 40 yards or so. I shoot most of my turkeys between 20 to 30 yards. I do have a new Rem. 20 I'm setting up, so maybe I will give them TSS's a try in that gun.
