The Federal Power-Shok 308 Winchester lead-free ammo uses a 150-grain solid copper hollow point designed for deer, hog, and medium game hunters operating under lead-free mandates. At 2820 fps muzzle velocity and 2648 ft-lbs of energy, this round pairs monolithic copper construction with Federal’s hunting-grade quality control. The deep hollow point cavity drives consistent expansion without fragmenting, creating wound channels wide enough to drop game quickly while staying California-compliant and suitable for lead-restricted hunting zones nationwide.
Built for the Box
Federal machines each 150-grain projectile from a single piece of copper alloy, eliminating lead entirely while maintaining weight retention through the expansion phase. The hollow point geometry opens predictably at impact velocities between 1800 and 2820 fps, shedding energy into tissue rather than over-penetrating. Boxer primers seat in reloadable brass cases, and the non-corrosive powder charge meters consistently across temperature swings. Federal rates this load supersonic with a G1 ballistic coefficient of 0.278, suitable for shots inside 300 yards where most hunters take whitetail and feral hogs.
