Can you shoot a shotgun slug through full choke barrel?

No, you should not shoot a shotgun slug through a full choke barrel. A full choke barrel is designed to tightly constrict the shot pattern, which can cause the slug to become unstable and potentially damage the barrel. Shotgun slugs should only be used with barrels that are specifically designed for them, such as rifled barrels or barrels with improved cylinder or modified chokes.
