I've heard of that too, but from what I gather it doesn't work verry well. The balls spread enough to give you three misses. Multi balls through a rifled barrel just doesn't work as well as shot through a shotgun. That's the real greatness to a combination gun like the old Savage over/under rifle shotgun combo. That way you really can have a rifle and shotgun for whatever you're hunting. (One of those is high on my want list, BTW)
