People do it all the time. But I know 4 guys that have bulges in there field barrels now. 2 brownings, 1 mossberg, and one 870. Do what you want but I would have a slug gun or slug barrel. for an sbeII you can buy 2 guns for the price of a slug barrel so whatever. If you do use your field barrel, companys made rilfed slug chokes(lead only right 10 gauge ) to. I don't know how they shoot so your on your own there.
