I have not hunted waterfowl in some years, but was living in one of the first steel shot areas ever required way back when., (SE Texas)

I am planning a trip to upstate NY this October for a partridge/black duck hunt and was thinking of using bismuth so as not to run afoul of lead shot in possession scenario at my remote campsite. Any shot size or load suggestions? 12 ga, 2 3/4 inch is my wheelhouse, Thanks!
