Headed to SoDak for a guided combo pheasant/waterfowl hunt in a few weeks. I'd like to try some of the newer Bismuth loads for waterfowl. What shells and loads and shot size are you guys using for Canada's and mallards? I'll be using a Fabarm Waterfowler so 12 gage and max 3 inch shell. I have a few 1 3/8 ounce loads of #4 12 gage Kent bismuth (10 shot box) I keep around for pheasant in no tox areas, but only have a few left in the box of ten so I need to pick up some more for the morning waterfowl hunts. I also seem to be striking out in finding much in stock for the Kent bismuth box of 25 waterfowl loads.
