Rio builds its Royal Blue Steel line (brand part no. RBSM404) in 12 gauge around a 3-inch hull loaded with 1-3/8 ounces of #4 steel shot, giving waterfowl hunters a nontoxic load with real reach. Rio rounds every steel pellet for consistent patterns and pushes the load to serious velocity so it performs when birds flare wide over the decoys. Built specifically for nontoxic waterfowl hunting, this shell is engineered to hold up in the wet, cold conditions that define duck and goose season. For hunters loading up on shotgun shells before opening day, Royal Blue Steel is a dependable nontoxic option.
