The Federal Power-Shok .243 Winchester 100-grain Jacketed Soft Point (JSP) Brass 20-round box is a proven centerfire rifle cartridge engineered specifically for harvesting whitetail deer, mule deer, pronghorn antelope, and feral hogs. A primary friction point when hunting with lighter .243 Winchester loadings is insufficient tissue penetration or erratic fragmentation on heavy shoulder bone and larger-bodied game. Federal addresses these terminal performance limitations by increasing sectional density with a heavy 100-grain lead-core projectile, delivering deep linear penetration, reliable weight retention, and wide vital-zone expansion with manageable felt recoil.
The primary technical advantage centers on the traditional copper-jacketed lead core featuring an exposed lead soft point paired with a 0.355 G1 ballistic coefficient. The exposed soft point initiates immediate, uniform mushrooming upon target contact across a broad range of impact velocities, while the heavy copper jacket regulates deformation to prevent bullet breakup. This structural balance ensures the projectile preserves mass to drive deep through hide, heavy muscle, and bone, creating broad, lethal wound channels.
Launching its 100-grain soft point bullet at 2,960 FPS and generating 1,945 ft-lbs of muzzle energy, this Power-Shok loading maintains a flat downrange trajectory while maximizing energy transfer at typical hunting distances. Assembled using premium reloadable Federal brass cases, non-corrosive Boxer primers, and clean-burning propellants, it guarantees consistent ignition, stable internal pressures, and smooth feeding across short-action bolt-action rifles and single-shot hunting firearms. It is an outstanding choice for deer season and farm pest management.
