Rochelle, I shoot an 870 SM, It will shoot most any brand of ammo as long as I stay away from #4 shot, The 4's just won't pattern out of my choke. I have the Rem. Ventilator choke, its a ported .655 choke and at 40 yards its awesome, I have a .660 Rhino choke on the way, everyone says that its the one for Hevi-Shot so I will find out.
