I've got a Carlsons .675 tube on my 835 now and I'm happy with how it shoots, just curious if there would be much difference in performance with the Indian Creek tube. I can't imagine there would be much difference just wondering if anybody had compared them. I'm currently shooting Winchester Double X 3.5 inch #5 shot but want to try some Hevi 13 3.5 #7 shot to hopefully get even better patterns.
