Winchester Copper Impact 300 WSM ammunition features a solid copper expanding bullet with polymer tip for rapid expansion and maximum energy transfer on big game.
Winchester's Copper Impact ammunition represents a modern approach to big game hunting, built around a solid copper expanding projectile that delivers consistent, devastating performance in the field.
The Copper Extreme Point bullet features a large-diameter polymer tip that initiates rapid expansion upon impact. Unlike traditional jacketed lead-core bullets, the solid copper construction provides superior weight retention through the target, maximizing energy transfer and creating larger wound cavities for faster knockdown.
Copper Impact ammunition is engineered specifically for hunters pursuing big game. The accelerated expansion and superior energy transfer make it equally effective on deer, elk, and everything in between. The solid copper design ensures consistent performance across a wide range of impact velocities and angles.
