I tried the Hevi-shot Hevi 13 in a 3.5" #5 shot and it patterned horibly out of my gun! I don't know if I can emphisize horribly enough. Everything that I have read about the load was suppose to be awesome and you were suppose to get great patterns, however, out of my Rem 870 SPS-T I got terrible results using a Primos Jellyhead choke. Of course, what may not work for me and my gun, may work for you and yours. It's one of those things where you have to give it a try for yourself and see what happens. Best shell I have used so far is the Federal flight control 3.5" #5 shot out of my Rem 870 SPS-T
