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 Prairie Storm FS Lead uses the rear-opening FLITECONTROL FLEX wad and a mixed payload of standard pellets and FLITESTOPPER lead to produce full, consistent patterns through any upland choke. Excellent retained velocity and energy mean increased lethality and fewer lost birds.
