Gary,
Here's another pattern from the Mad Super Max .675 choke and the Hevi-13 2oz #7 loads. I have only shot this choke maybe 4 times now and one was at the turkey above. But look at this pattern in a 10" circle at 40yds. You can't get much better than that from a factory load.
Here's the backside of that pattern so you can better see how it patterns. That is a turkey thumper right there. I love that choke and load.
