FWIW:
I have Carlson's HW/TSS chokes in both 870's and my BSN and they pattern VERY well with 2oz/#5 12/3.5" WLB shells. If a Tom's head winds up anywhere inside a 12" circle out to 50 yards there will be no chance for survival.
For roughly $2 each the Winchester Supreme Long Beard XR's shoot so well out of all my turkey guns to 60 yards, I simply can not justify it and bring myself to spend $8 each for TSS.
