Winchester Copper Impact 300 WSM 150gr Lead-Free Ammo 20rd Box

The Winchester Copper Impact 300 WSM ammunition delivers maximum terminal performance with its advanced lead-free copper construction. This 150-grain cartridge features Winchester's Copper Extreme Point technology, engineered for rapid expansion and deep penetration across diverse hunting conditions.

What Makes This Different

The Copper Extreme Point bullet design incorporates a large diameter polymer tip that drives expansion at both high and low velocities. Unlike traditional lead-core bullets, the solid copper construction maintains 95-99% weight retention while creating devastating wound channels. The lead-free formula meets all hunting regulations in California and other areas with non-toxic ammunition requirements.
