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. Lastly, the casing. The precision-built cases in most centerfire Premium loads feature nickel-plated brass that defeats corrosion and aids in sleek, smooth extraction in even the most extreme conditions. Push effective range to new extremes while delivering a more lethal blow on impact with Swift Scirocco II loads. The polymer-tipped bullet's streamlined design and high ballistic coefficient produce flat trajectories, while retaining more velocity and energy downrange. Aided by its Signature Black Tip, the bonded Scirocco II expands at minimal velocities yet offers high weight retention at close range thanks to its bonded copper jacket.
