Steve, I shoot the HD's out of my 870 SPS-T and Jellyhead .665. Out of them, the Win. Xtended, and the hevi shot, the HD's pattern the best in my gun. I have always used the old Rem. Hevi shot, but they don't make them anymore. The HD's even patterns better than them. Each setup is different. HD's work better in mine. You may want to give them a try. They work great for me. I use the 3 1/2 6 shot.
