This year we are aloud to shoot #7 shot.we were stuck with 45&6 shot for turkeys.i have a 870 super mag and have had great luck with federal flight controlled wad shells and then the longbeard. I am looking at the TSS in #7 Will my factory rem extra full turkey choke work with this heavy shot ...
I would look at the Federal Heavyweight #7 over the TSS. More pellets and hit like #4s. If your gun likes the Flight Control Wad, www.rogerssportinggoods.com has them for around $15.00/box of 5 if remember right. Try a box and if they shoot well then order as many as you can as they have been discontinued. Not many guns like the Flight Control Wad, but if yours does, those shells are monsters. No need for TSS with a good pattern of those in any gun.
