RE: Remy 870
I would shoot the sabots out of the slug barrel. The slug barrel should be rifled. The foster style in the smoothbore can only shoot to about 50 yards accuratly without a significant amount of drop. So if you plan on shooting short distances I would go with them. I shoot an 870 super magnum with the slug barrel with remington core-lokt 395 grain sabots. I can easily shoot out to 150 yards. I don't use a scope though. It gets tough sometimes to shoot that far but I am comfortable shooting that far without a scope.
