If you`re happy with the 500 you could just get a rifled barrel for it. If your wanting the best accuracy possiable pick up a gun that has the scope mounted on the barrel or the barrel is screwed into the recever. If you can stand ugly, Mossburg makes a bolt action that shoots real well, but it`s a slug gun only. H&R, Nef also make a single barrel that is suposed to shoot well.
