All right fellas got some questions for the experts. I've been shooting 4x5x7 nitros in 3.5" 870 and 3" 11-87. Want to try some Hevi-13 in both the 3" and 3.5" #7 and also 5x6x7. What do you think about the h13 5x6x7 compared to the straight 7. I want some good 40 yd #s without buying a new choke. I have a Jellyhead/RSF/and a few others. Thanks for the help.
