"Federal Premium Black Cloud FS Steel Waterfowl 12-Ga. 3-1/2"" 1-1/2 oz. Shotshells now come equipped with the FliteControl Flex wad for improved pattern density and consistency through both ported and standard chokes. The rear-deploying petals have reinforced gussets that deploy when fired through ported chokes, decreasing muzzle pressure. Side-mounted slits stimulate payload separation from the wad for lethal accuracy. Catalyst lead-free primer and clean-burning propellant decrease residue in your shotgun's barrel and action. Because of its temperature stability, the propellant ensures consistent velocities and required leads from a hot opening day through a frigid late season. FliteStopper steel pellets mix with standard steel pellets to deliver superior downrange patterning and knockdown power. Unlike standard round steel pellets, FliteStopper pellets have a sharp cut-on-contact surface that produces bird-slaying wound channels unlike anything you've seen before.
