The Federal Premium loads start with the finest primers, which are subjected to more frequent inspections for dimensional tolerances and charge weight to ensure they deliver consistent ignition for every shot. Next is the propellants, which are specially formulated to meet Federal's stringent specifications. These clean-burning powders are of the highest grades in the industry. They're consistent and reliable. The Black Cloud FS Steel is equipped with Federal's Flitecontrol Flex wad to deliver improved pattern density and consistency through both ported and standard waterfowl chokes. The wads redesigned rear-deploying petals and side-mounted vents stimulate the payload for separation from the wad at the ideal moment for dense, deadly patterns. It also features a payload of 40 percent FLITESTOPPER steel pellets and 60 percent Premium steel with high-performance primer and clean-burning, temperature-stable propellant, plated head, and a sealed crimp that defeats moisture in extreme conditions.
