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. Go beyond what you ever thought possible with Terminal Ascent. Bonded construction penetrates deep on close targets, while the patented Slipstream polymer tip initiates expansion at velocities 200 fps lower than comparable designs. The bullet's long, sleek profile offers an extremely high ballistic coefficient, and its AccuChannel groove technology improves accuracy and minimizes drag.
