I shoot 3 1/2 kent faststeel out of my SB11 with the pattern master choke. They are all about the same just gotta put the bead on em.
Different types of loads/chokes for different types of hunting.. It depends on the area (ponds, lake, river, bay, fields) you are, birds your after and which season (early or late)...However, I've seen some pretty big differences at the pattern board with different loads/chokes.
