I have traded in my benelli pump, which I could n't hit a thong with for a nice old aya boxlock 3" magnum with 30" barrels choked full and full. It will be used mostly for wildfowl on the esturies - widgeon and geese, with non toxic shot (but probably not steel). My feeling is full / full is a bit tight and should have it opened up to 1/4 and 1/2. It is a fixed choke gun so cannot change back. Any thoughts please.
