Rio Royal BlueSteel Magnum shotshells (brand part no. RBSM363) load a heavy 1-1/4 ounces of #3 steel shot in a 12 gauge, 3-inch hull, stepping up both payload and pellet size from Rio’s standard BlueSteel loads for hunters chasing larger waterfowl at extended range. Steel shot is lighter than lead at the same size, so it carries less energy per pellet and patterns differently, which is why Rio pairs this heavier charge with a larger #3 pellet built specifically to retain knockdown power on big geese and large ducks. The 3-inch magnum hull is required to hold this heavier charge, so it will not fit a 2.75-inch-only chamber. For waterfowl hunters who need maximum steel payload and pellet size, this shotgun shell from Rio Ammunition is built for exactly that.
