I've got an old Mossberg .410 and I have always wanted to try shooting slugs from it just to see what it was like but I'm not quite sure if I can. It is a model 183 and it has a weird choke at the end and I don't know if its safe to shoot slugs from it with the choke. Have you guys ever shoot slugs from this model and if so would I have to shoot rifled slugs? Thanks
