I have 5 win 1300's with about 25 different chokes to go with them. I do not like #6's therefore I never pattern them. However I have run thousands of 4's and 5's through them all. If your gun has sights I will say that the IC will be great. This choke patterns incredible but very rarely does POI match POA in any of them. I hunt a front bead only so I chose a different choke that hits more centered.
