Winchester Copper Impact Ammunition 300 Winchester Short Magnum (WSM) 180 Grain Copper Extreme Point Polymer Tip Lead Free 20RD

Winchester Copper Impact ammunition in 300 WSM delivers a purpose-built round for hunters who demand terminal performance and reliability. The 180-grain Extreme Point bullet is a solid-copper design engineered to transfer energy efficiently and create lethal wound cavities. This lead-free cartridge pairs modern ballistics with the knock-down power serious hunters expect from a magnum round, making it a solid choice for medium to large game at extended range.

The Extreme Point bullet design centers on an oversized impact diameter that maximizes energy transfer on contact. Solid-copper construction means superior weight retention through the target—deeper penetration translates to more reliable performance in real-world hunting conditions. The reinforced polymer tip in red is engineered for consistent expansion and predictable terminal ballistics, while the hollow nose cavity is designed for lethal performance at typical hunting distances.

Winchester built this load with a streamlined ballistic profile and boattail to flatten trajectory, so your 300 WSM shoots flatter and drifts less in wind. Each box contains 20 rounds—enough for practice, load development, and a solid season in the field. If you're running a 300 WSM and want ammunition that's built for hunting rather than generic shooting, Copper Impact ammunition delivers the terminal design and consistency Winchester shooters trust.
