I bought the Remington 870 Express Combo which comes with a smooth bore bird barrel and a rifled slug barrel. Now here's my question.... I've heard mixed things about shooting regular slugs through a rifled barrel. Some people tell me it's ok, and others say no way and to ONLY use sabots. When I checked the manual to the gun, it didn't mention anything at all. Anyone have an opinion? I'd love to go out and practice more often, but at $10 for a box of 5 shots, that can get damn expensive. Hell, for $10 worth of ammo, I could shoot a .22 rifle all weekend
