I use #4 kent bismuth 1 1/4 oz early and 1 1/4 oz #3 TM late season in my Super Foxes and 3 frame 12ga Parkers. In my 2 frame Parkers I use 1 1/8 oz bismuth handloads with a psi of 9000 psi and 1150 fps #4 shot. Next to Kent TM the best way to insure you bring birds to bag is a trained retriever. :)

them should be some really good water fowl loads....charlie
