I've been using a MAD choke in my 870 Super along with Winchester Supreme Elite Xtended Range 3.5" 6 shot and also patterned the Fed Flight Control and Hevi Shot as well. Winchester Xtended range patterned best with my choke followed by Hevi shot and then Fed Flight was the worse. Those Xtended Range hit hard at 40 yards too as it actually knocked the wooden target over whereas the other two just waivered it.
