I shot some hevi 13 6 shot out of my mossberg/Indian creek gun last weekend and will never buy that particular shell again. Terrible pattern at 40+ yards. My winchester 6 shot out performed the HV. Now I've read the new HV 6 shot is worse than the older. Can't remember the colors of the shells, but the older ones were the bomb. I had the newer ones. I still might try some 3.5's and see if that makes a difference, but for now I'm gonna try the winchester extended range 6 shot.
