Jeff, these guys bought into the hype of BC. Being the "ultimate" final answrr in waterfowling. I shoot an extended range Patternmaster, with Either Estate, or Federal bkue box steel, and don't have a problem at any sensible range
Whatever I can get on sale at Dunns, used to be 99 a case for 3 inch around 1450 fps IIRC. Pattern it when you pick which one you are going to use and life is good.
Federal steel 4s have killed a LOT of birds for me.
I don't buy into gimmicks and the newest best stuff....
