If it was me, I would shoot smoothbore slugs out of an improved cylinder barrel. If your shots are under 100 yards this would be a good setup for slug shooting. I hunt deer with an Remington 870 Wingmaster shotgun with an improved cylinder slug barrel, using smoothbore Remington rifled slugs as this setup works great for me because most of my shots at deer are 50 yards and under. So my advice to you is to get an improved cylinder choke for your supernova and try the Remington smoothbore rifled slugs in it. Good luck hunting.
