The Hornady Outfitter 300 Weatherby Magnum 180gr lead-free rifle ammunition is built for hunters and long-range shooters who won't compromise on performance in harsh conditions. Loaded with Hornady's monolithic copper alloy GMX bullet in a 180-grain configuration, this round combines the flat trajectory and power of the venerable 300 Weatherby Magnum with modern lead-free construction—ideal for Western hunts, backcountry trips, and states with ammunition regulations. Each 20-round box ships in nickel-plated, sealed cases designed to shed moisture and corrosion, so your ammo stays reliable whether you're glassing alpine basins or hunting wet coastal terrain.
The GMX bullet at the heart of Outfitter ammunition is engineered for controlled, deep penetration and exceptional weight retention—critical when pursuing game at distance or through heavy cover. Because it's a monolithic design (no lead core), it delivers consistent ballistics and energy transfer while meeting California and other non-traditional-bullet jurisdictions. The polymer tip aids aerodynamics and helps initiate reliable expansion on impact, making this load suitable for medium to large game at typical hunting ranges.
Hornady's attention to sealing—both at the primer pocket and case mouth—keeps moisture out during storage and transport. Nickel plating on the brass adds another layer of corrosion resistance, so your ammunition functions flawlessly even after months in a pack or vehicle. Whether you're a handloader who respects factory quality, a Western hunter navigating lead-free zones, or simply someone who demands ammo that performs in the field, Outfitter ammunition is a no-excuses choice for the 300 Weatherby Magnum.
