Steel in my old Mossy 500
The gun is actually an old New Haven 600AT(about 25 years old), which is the Monkey Wards/Sears rebrand for the Mossberg 500 (exact same gun). Has a fixed Mod choke, and the gun has been great for dove and quail. Also used it for ducks twice this past season, and I'm wondering if the steel shot is going to screw up my barrel. Not sure if it make a difference, but I almost always use 3" shells when hunting ducks with steel shot.
