yes for a shotgun you need a rifle barrel DO NOT shoot slugs if you have a poly-choke!
No, not without barrel inserts.
Yes.
You can, but, it will not be a good thing.
with the wingmaster barrel you can only shoot lead, but if you change the barrel to a slugster you can shoot slugs and buckshot, they also have a barrel for steel shot to.
