You can shoot rifled slugs through a rifled barrel, it causes little to no damage at all to your barrel. However, I was told by a respected gunsmith that once you shoot a rifled slug through a rifled barrel, you must not switch back to sabots as this will cause damage to your barrel.
I wonder what "other" mis-information this gunsmith is spreading?
Perhaps he "ment" the bbl should be cleaned first, "incase" the lead slug left any lead in the bbl.???
