I don't know how it compares to the moss, but depending on how well you shoot it, you should have a good deal on your hands with a browning 10. I'd go with either 3 1/2 slugs, out to 60-100, depending on you, or 00 buck-4 shot out to 60, also depending on you and your patterns with it. I use a 12 J.C. Hig. made Sears and roebuck (old school!!) with slugs out to 125 and have been satisfied, you should be able to do just as well if not better with the browning 10 ga.
