yes it can shoot slugs
NO you can't shoot slugs from it - why would you want to!
yes for a shotgun you need a rifle barrel DO NOT shoot slugs if you have a poly-choke!
Pellets or slugs. shotguns usually shoot shot or pellets, but you can shoot slugs. in Indiana we use a shotgun to hunt deer and use shotgun slugs, better to use a barrel with no choke in it. cylinder bore preferred.
Guns that shoot slugs are specially designed for slugs. It depends on your gun but most are not designed for this purpose I do not recommend testing it for if they are not the right barrels they WILL break.
yes you can but onaly riffled slugs
Rifled barrels are meant for sabot slugs. Rifled slugs are fired from smoothbore barrels.
