I shoot a sbe II with a trulock .665 5 shot winchester 3.5" this patterns well but My old sbeI with a kicks.660 with the same load was awsome 35-40 hits in the kill zone at 40 yards. when I bought my sbeII kicks did not make A crio choke.
Bolth the trulock and the kicks choke are ported
I think that helps alot.
Hope this is some help
