I have and would strongly recommend getting a 20 ga. H&R ultra slug hunter. It is a relatively inexpensive single shot with a fully rifled barrel. Mine is scoped with a 1.5-6x32 scope and with slugs it likes it is definitely under 1.5-2" group at 100 yards. Usually it is much better than that and it is not at all rare to have holes touching at 100 yards. Some places I hunt require a slug gun or muzzleloader and I will pick this slug gun every time. The only downside is that it is a little heavy since it is actually a 12 ga. barrel that they only bore to 20 ga. essentially making it a bull barreled slug gun. The H&R 12 ga. ultra slug hunter is really heavy (10 ga. bored to 12 ga.)
