Federal Black Cloud 28 Gauge 3in #3 3/4oz Waterfowl Shotshells - 25 Rounds - The best load in waterfowl hunting has never been so deadly. Federal Premium Black Cloud FS Steel is now equipped with the FLITECONTROL FLEX wad to deliver improved pattern density and consistency through both ported and standard waterfowl chokes. The Premium Black Cloud wad's redesigned rear-deploying petals and side-mounted vents stimulate the payload for separation from the wad at the ideal moment for dense, deadly patterns. Plus, the Federal high-performance primer and clean-burning, temperature-stable propellant significantly decrease residue in the barrel.
