The Winchester Copper Impact Rifle Ammo 270 WSM 130 gr delivers a hunting-grade solution in the Copper Impact series for serious deer and elk hunters who demand fast knockdown and reliable long-range performance. With a 130 grain Copper Extreme Point lead-free projectile launching at approximately 3215 fps and producing about 2983 ftlbs of muzzle energy, this load gives you rapid expansion on impact thanks to its large-diameter polymer tip while maintaining a high ballistic coefficient and boattail profile for a flat, accurate trajectory at extended ranges. Because the solid copper construction retains weight and transfers energy efficiently, you get larger wound cavities and more dependable terminal performance across big game species, and the brass casing and American origin provide consistent chambering and extraction. Use it for mountain hunts where precision and retained energy matter or for plains and timber work where quick, humane stops are critical; the Copper Impact series balances controlled expansion with penetration for mid- to long-range shots. If you want lead-free, high-velocity 270 WSM ammunition that reads well on ballistics charts and performs in the field on deer, elk and similar game, this Winchester offering is engineered for those results.
