Well right now I shoot Winchester Double-X Magnums (3.5" 2 1/4oz #5) through my Mossberg 835 (Primos Jellyehead), and those pattern really well. So I would IMAGINE the #6's would throw out one hell of a pattern. I got my new Mueller scope on my gun too, so i have to sight in/pattern again anyway so i might as well try another load. Thanks
