These do have the Flight Control Flex Wad.

I have three chokes to try: the standard full choke that came with the gun, a Briley Extended Extra Full Choke .735, and an Indian Creek Black Diamond .690. Wondering how the Federals will do out of the Indian Creek. It has some pretty aggressive wad striping rings in it.
