Winchester Copper Impact ammunition in 300 Winchester Magnum is built for hunters who demand ethical, effective performance on medium to large game. This 180-grain load pairs a solid-copper Extreme Point bullet with a reinforced polymer tip, delivering the stopping power and deep penetration serious long-range hunters expect from a magnum cartridge. Winchester engineered these rounds from the ground up for terminal performance—not as an afterthought—making them a genuinely different choice from typical off-the-shelf magnum ammo.
The solid-copper bullet construction is the foundation of what makes this ammunition stand out. By eliminating the lead core entirely, Winchester achieves superior weight retention through the target, meaning less energy loss and deeper, more reliable penetration on hard-bodied game. The Extreme Point design features an oversized impact diameter that creates a wider trauma channel and faster energy transfer on impact. That translates to faster knockdown and more decisive terminal ballistics in the field—the difference between a clean, ethical harvest and a wounded animal.
Ballistically, the boattail design and streamlined profile keep the 180-grain bullet flying flat downrange, critical for the extended ranges where a .300 Win Mag truly shines. The hollow nose cavity works in concert with the copper construction to ensure lethal expansion while the solid build prevents the fragmentation that can waste energy and reduce penetration. Each box contains 20 rounds, plenty for zeroing, practice, and a season's worth of hunting.
If you're running a .300 Winchester Magnum for elk, moose, or long-range hunting and want ammunition that's engineered specifically for terminal performance—not just loaded to SAAMI specs—Copper Impact deserves a hard look.
| Caliber | 300 Winchester Magnum |
| Bullet Weight | 180 Grains |
| Bullet Type | Copper Extreme Point, Polymer Tip |
| Bullet Construction | Solid Copper, Lead-Free |
| Rounds Per Box | 20 |
Yes. The Extreme Point bullet is constructed from solid copper with no lead core, making it compliant with lead-free ammunition mandates in California, certain National Wildlife Refuges, and other regulated areas.
The 180-grain Copper Impact is designed for medium to large game hunting. The solid-copper construction and Extreme Point design deliver the penetration and energy transfer needed for elk, moose, and similar-sized animals, particularly at extended ranges where the .300 Win Mag excels.
Each box contains 20 rounds.
Solid-copper bullets retain more weight through the animal than traditional lead-core designs, meaning deeper penetration and more consistent energy transfer. Combined with the Extreme Point's oversized impact diameter and hollow nose cavity, this design maximizes terminal performance and reduces the chance of incomplete, unethical kills.
