The Winchester Copper Impact .308 Winchester 150-grain Copper Extreme Point (CEP) Solid Copper Brass 20-round box is an advanced, lead-free centerfire rifle cartridge engineered specifically for medium and big game hunting in regulated zones and lead-restricted environments. A primary friction point when hunting with monolithic copper bullets is slow or inconsistent expansion at extended distances, which can lead to pencil-through pass-throughs without sufficient energy transfer. Winchester resolves this non-lead terminal challenge by topping a solid copper alloy bullet with an oversized polymer Extreme Point tip, ensuring rapid hydraulic upset upon impact while retaining nearly 100% of its initial weight for deep penetration.
The core technical advantage relies on the oversized polymer tip paired with the solid copper body construction. Upon target contact, the wide polymer tip acts as a wedge, driving deep into the hollow nose cavity to initiate immediate, wide-diameter expansion even at reduced downrange velocities. Because the projectile is manufactured as a monolithic copper unit rather than a lead core wrapped in a jacket, it eliminates jacket-core separation, driving through tough hide, dense muscle, and heavy bone structure while preserving mass and energy transfer into vital organ zones.
Launching its 150-grain projectile at 2,810 FPS and producing 2,629 ft-lbs of muzzle energy, this .308 Win load features a sleek boat-tail profile that reduces aerodynamic drag to maintain flat trajectories and downrange velocity. Assembled in precision-drawn, reloadable virgin brass cases fitted with non-corrosive Boxer primers and clean-burning propellants, it delivers smooth feeding and reliable extraction in bolt-action and semi-automatic hunting rifles. It is an exceptional, high-reliability choice for whitetail deer, mule deer, pronghorn, and wild boar.
