I believe this is correct, too (at least this is what I have read). Your pattern seems to be pretty nice and evenly distributed. You never mentioned what size shell you shot, but from looking at your patterning target, I saw that it was a 3" shell. I have a that I just bought of the newer Xtended Range Supreme Elite that I am going to pattern. I have a Jellyhead choke as well that I will try out and I also have a new choke coming in the mail that I am waiting to get before I go out to do the patterning.
