For deer, elk, and hog hunters who demand controlled expansion and deep wound channels, the Remington Premier 308 Winchester 165-grain Swift Scirocco II delivers bonded-core construction at 2700 feet per second. This is 308 Winchester hunting ammo engineered around the Swift Scirocco II projectile — a polymer-tipped, boat-tail design with a pure copper jacket chemically bonded to the lead core. That bond eliminates jacket-core separation on heavy bone or quartering shots, and the secant ogive nose profile pushes the ballistic coefficient to 0.47, flattening trajectory beyond 300 yards. The result: predictable energy transfer, over 75% weight retention across impact velocities, and the accuracy you expect from match-grade brass.
Built for the Box
Remington builds this load in new-production brass cases with non-corrosive Boxer primers, making spent hulls ideal for handloading. The 165-grain weight splits the difference between lighter varmint bullets and heavy barrier rounds — you gain flat flight without sacrificing sectional density (0.248) or energy on impact. At the muzzle, you’re launching 2670 foot-pounds; downrange, the polymer tip initiates expansion while the bonded jacket holds together through hide, muscle, and bone. Velocities stay supersonic well past ethical hunting ranges, and the boat-tail base sheds drag for consistent wind performance.

This load joins the Remington 308 Ammo lineup as a purpose-built hunting option — pair it with any 308 Winchester bolt gun or semi-auto with a 1:10″ or faster twist. The polymer tip seats consistently for reliable feeding, and the bonded jacket design holds up under high rotational stress.
