I have a Mossberg 12ga. w/a Rifled cantilever barrel, and was wondering what kind of performance(if any) I would see with 'Rifled'-Slugs... I'm planning on Sighting-in, and Hunting with the Hornady SST rounds, but they are too expensive for Me to 'Plink' with... Am just seeking an Inexpensive alternative for this Barrel when not on the 'Hunt'. I do not have Reloading capabilities, so that's not an option for Me. Any suggestions ???
