WTB: Remington 870 20 Guage Cantilever Rifled Barrel

[summitdogracing]

My 13 year old son won a CDFW Jr. Pig Hunt (Shotgun/Archery only). He has a Remington 870 Express Youth smoothbore. It is impossible to find a rifled copper slug for the hunt. It looks like the best alternative is to find a barrel to swap out. Your help will be greatly appreciated.
