From what I have been reading, the flitecontrol wad was designed to keep all of the shot together until a certain point. The Jellyhead choke is designed to strip the wad from the porting. I was told that it just might cancel out the objective of the FCW. I'd be interested though in knowing your results because it seems like a great shotgun shell and I bought a .655 Jellyhead for my new Stoeger M3500.
