Winchester Copper Impact 300 Winchester Magnum Lead Free 180 Grain 20 Rounds

The Winchester Copper Impact series 300 Win. Mag. 180 gr Copper Impact LF delivers big-game stopping power with a conversation-friendly run-through of why hunters choose this load: a solid copper expanding projectile and Copper Extreme Point lead-free design combine with an accelerated-expansion polymer tip to produce rapid impact trauma and larger wound cavities for faster knockdown on deer, elk and heavier game, while the high ballistic coefficient and engineered boattail give a flat trajectory and stable long-range flight, making follow-up shots more reliable at extended yards. With a muzzle velocity around 2950 fps and muzzle energy near 3478 ft—lbs this load carries the energy to reach vitals and transfer it effectively through solid copper construction that maximizes retained weight. If you're dialing in a magnum rifle for mountain elk or plains whitetails, the brass-cased, US-origin Copper Impact line offers consistent chambering and ignition behavior that pairs well with precision optics and range-tested loads; the lead-free projectile also meets land-management and hunting area restrictions while delivering devastating terminal performance on big game.
