Yeah I thought about selling the 7's but I may just keep them. Won't get what I paid for them so whatever. You're right, I had about the same number of pellets just outside the 10 circle as in it with the 7s. It was very evenly distributed. I borrowed a choke though so I still don't have a non-ported choke.
I killed 2 in one shot last year with these 4s at 11 yards, same gun. Rifled signs came in handy. I'm surprised I didn't cut the first ones head off but it was still attached
