I don't have that exact model but I do slug hunt with an 870. They are great guns. Try Hastings 2 1/2 inch magnum laser accurate slugs in it as well as lightfield hybrids. They are very accurate slugs out to 100yds, maybe a little further. You will probably find that 2 3/4 slugs are more accurate than 3 inch slugs. I would not bother with the faster slugs like the hornady's and rem accutips unless you are planning to be shooting out past 120 yds with it. If you are strictly jump hunting with it, I would suggest a red dot site. If you are going to take shots out past 75 yds, get a low variable power scope for it like a 1-4, 1.5-6, or 2-7 power.
