Product Description Winchester Copper Impact is built for big-game hunting with a Copper Extreme Point projectile designed to expand rapidly on impact for fast, effective energy transfer. The solid copper construction delivers improved weight retention compared to traditional jacketed lead-core bullets, while the large impact diameter helps create greater trauma and larger wound cavities for quicker knockdown. This .243 Winchester load features a lead-free bullet and comes packaged 20 rounds per box (10 boxes per case).
