I have heard of Fatt Butt calves getting really pipe gutted. I have seen some awesome ones, but also seen some really shallow ones. I know that happens in every bull, but I will tell you one bull thats a simmy that I really like his calves out of heifers and thats Dream Catcher! But I think Fatt Butt could work too. Hes either really going to work or really not going to work
