Yeah, I don't recommend that ammo either. I bought a bunch of it and it shot like crap. Stick with either slug or buck. I would recommend Ddupleks for slugs. you can safely shoot those slug rounds all the way up to a full choke with no problems. But again, this goes back to all the choke questions, which I also had a bunch,and there are tons of post on this topic if you search this forum for it. Hope this helps.
