The Winchester Copper Impact Rifle Ammo in 243 Win with an 85 gr Copper Impact LF bullet from the Copper Impact series brings big-game stopping power to hunters who demand rapid expansion and reliable long-range performance, with the Copper Extreme Point lead-free projectile producing accelerated expansion through a large-diameter polymer tip for immediate trauma and supreme energy transfer for fast knockdown on deer, elk and similar game. With a high ballistic coefficient and engineered boattail the bullet holds a flat trajectory out to long ranges, delivering 3260 fps muzzle velocity and about 2005 ft-lbs of energy for effective terminal performance, while brass casings and a United States origin provide consistent feeding and compatibility with standard bolt and semi-auto rifles chambered in 243 Winchester. If youre glassing a ridge or running a stalking hunt, the Copper Impact line gives predictable expansion, retained weight for deep penetration, and reduced lead concerns thanks to its lead-free construction, making it an excellent choice for hunters focused on humane exits and reliable downrange accuracy. The cartridge is ORM-D classified for handling and integrates well with hunting optics and modern cartridge selection for centerfire rifle shooters.
