What are you hunting? Finding a serviceable 16 gauge black powder shotgun will not be easy in either muzzleloader or break barrel. Don't rule out a 12 or 20 gauge since you can adjust your load (if reloading shells, or muzzleloading). I use a 10 gauge sxs muzzleloader when I don't plan to move around so much, like still hunting for turkey. I like the backup shot, but the gun is kind of heavy to walk around with so I use a 20 gauge single barrel (.62 cal) smoothbore for squirrels and sich, or ball for deer. Others may have different preferences, but those are mine.
