Just me but I bought a box of Remington 3" nitro turkey loads with 1 7/8 oz #4 shot on close out a couple of years ago figuring I might go turkey hunting some day. Think I paid $4 or so. Got my chance to go last week . Screwed in the full choke tube in my old 870 express and found my shells. A nice Tom stuck his head up at about 40 yds. And I lined the bead up on him and it literally rolled him. The guy I went with is a 3 1/2" super full choke guy and he couldn't believe it. I'd buy some shells with either #4 or #5 in at least 1 1/2 oz and not worry about it. I mean now that I think about it I've killed Pheasent at 40-45 yds dead in the air with 11/8 oz of #6 and a modified choke numerous times with plenty of penetration. So throw in an additional 1/4-1/2 oz of shot or so to add to the density and a turkey should be doable .
