Thank you all, sorry about not providing more info, it is a H&R Ultra Slug Hunter in 20 ga. It does have a rifled barrel, that will shoot up to 3" ammo,
and has an attached scope base. So far I have read some reviews with some favorites, Remington Accu Tip slugs, Lightfield sabot slug,
and Hornady SST Slugs. Unfortunately many don't mention if they use the 23/4" or 3". I know the people in here will not steer me wrong. :gun1: I don't have a scope for it yet.
thank you all.
