That gun loves the Carlsons LB choke. I have never liked 5"s out of my 1300's though. I have gone back to LB 4's and the carlsons choke. I have about 20 different chokes for that gun that I always tinker with. They also Like indian creek but my gun throws low right with my Ic and since I only hunt a bead I did not stay with it. Gun also likes jebs. This is not 1 gun. I have a bunch of 1300's.
