Problem with those beautiful guns is they really can't be used with steel shot for us waterfowlers.
Way back when, I acquired a BSS and had the bores opened up to IC/IC and for years used it as my primary gun. SOld it.
Acquired another that has not yet been fired with the intention of getting the chokes again opened up this time to S1/S2. Has ejectors the mechanical trigger and 28" barrels. This to my knowlege is the only real viable option for the waterfowler today who wants to safely shoot steel from a side by side. Problem is that I've gotten so used to my SBEII and my hunting has slowed down that I've never gotten around to doing it.
