I have a SX3 NWTF I think they are similar, I put a Briley .665 choke on it and shot longbeard #5's. 40 yard pattern was so tight and I don't have a more open choke so I'll just continue to shoot supreme HV #5 shot. My SX3 came with a .655 on it. If you like tight patterns and lead shot you will like longbeards.
