I shoot an 870 SPS-T. Basically a super mag just for turkeys. I use a Jellyhead choke and Remington Wingmaster HD in 3 1/2" 6 shot. It is devastating. This combo will reach out and get them if need be. I shot two last year at 51 and 55 yards. I never thought I would find a round that would replace the old Rem. Hevi shot mags, but the HD's did. I tested several top shells ( Hevi 13, Hevi shot blend, Win. Extended, Federal Flight control ), and the HD's outperformed them all. Of course each setup is different. The heavier than lead loads are worth the extra dollars.
