The Federal Power-Shok .300 Win Mag 180-grain Speer Hot-Cor Jacketed Soft Point (JSP) Brass 20-round box is a high-performance centerfire rifle cartridge engineered specifically for medium-to-large big game hunting where deep penetration, structural integrity, and controlled expansion are required. A common friction point with high-velocity magnum cartridges is jacket-core separation upon striking dense muscle or heavy shoulder bone, which drastically reduces retained weight and limits penetration depth. Federal resolves this high-velocity terminal challenge by loading Speer's Hot-Cor bullet, where molten lead is poured directly into the jacket during manufacturing to form a mechanical bond that resists fragmentation upon impact.
The technical advantage focuses on core-jacket cohesion combined with predictable long-range external ballistics. Launching its heavy 180-grain Speer Hot-Cor JSP bullet at a stout muzzle velocity of 2,960 FPS (generating a massive 3,498 ft-lbs of muzzle energy), this traditional big game load flattens downrange trajectories across open terrain. Mechanically, the exposed lead soft point initiates immediate, uniform mushrooming, while the Hot-Cor mechanical bond holds the core and jacket together under intense impact stress. Featuring a 0.439 G1 ballistic coefficient, the projectile retains downrange speed and directional stability to carve wide, deep wound channels through heavy vitals.
Slinging its 180-grain Speer Hot-Cor bullet at 2,960 FPS, this specialized .300 Winchester Magnum cartridge is optimized for flawless mechanical operation across modern bolt-action rifles and long-action hunting platforms. Assembled in premium, heavy-walled reloadable virgin brass cases fitted with clean-burning propellants and non-corrosive Boxer primers, it maintains consistent chamber pressure curves and reliable ignition in extreme hunting temperatures. The precision-drawn brass cases ensure reliable chamber sealing, smooth feeding, and effortless casing extraction when executing critical follow-up shots on North American big game.
