Yes, but, it is an exercise without a point.
Mossberg 500A "combo" with 28" accuchoke vent rib barrel and 20"rifled slug barrel. About $300 U.S.
I found this answered in another persons question posted, they said not to as it could expand the barrel and have to much pressure. not knowing this I shot 3 slugs each through 2 differant 12 gage guns both full choked at a sight in range and one more to take down the deer just this last fall. & hope I did not damage my guns. they sighted off by 1 foot @ 50 yards so I did have to compensate aim. I am looking for a riefled gun now...
