i had a guy tell me that since i have a rifled slug barrel i need to shoot sabot slugs out of it. he said if i dont the rifling will collect lead from the regular slugs and it will start to shoot all over the place. what gives? i thought as long as they were rifled slugs i could shoot them out of my rifled slug barrel. and what about the cheapo slugs ive been using, brenneke ko or whatever, i put up like a 3 inch group off hand just screwing around the other day at 50 yards. i dont think my accuracy is suffering, maybe i havent shot enough cheap slugs through it yet.
