Using the proven technology of Federal Premium's Black Cloud that have proven to be the most lethal steel to date, modified to meet the needs of the most demanding upland hunters. Never before have loads delivered such full, consistent patterns. A mix of copper-pladed premium lead and nickel plated FliteStopper (FS) lead gives these loads the best down range performance to date.
