I have tried Winchester Heavy target 6-7.5 and Remington HV 6-7.5
I have even tried buckshot. In an attempt to beat the system last time I kept 3" turkey loads in my side saddle for those hard to knock down targets. It worked but I definately felt the recoil of that one.
I think that I am going to just wait till Christmas and go get that 1100 CM. I can't find a gunsmith around here who will thread my current barrel and Mossberg only sells a 28" barrel with chokes because it is their 8-shot model. I've gotten the validation that was required to get a new gun. I appreciate the help.
