I had an older 870 Express and the best patterns it ever shot was with the Remington Premier 2 oz. #5. Also shot regular old Nitro Mag #4 very well, regular full choke. I have always had excellent luck with the Remington loads whether it be Nitros or Premier, only difference is Nitro's are just hardened and Premier loads are copper plated, wads and buffering are the same. Both of my 10 bores love Premiers and I even have a few old Nitro Mags that will get used up on a few more birds before I run out of them. Anybody that wants to send me any Remington turkey loads PM me and I will let you ship them my way.
