The Hornady Outfitter 338 Win Mag 225gr CX Polymer Tip Lead-Free ammunition is built for hunters who won't compromise on performance or environmental responsibility. Loaded with Hornady's monolithic copper alloy GMX bullet, this is centerfire rifle ammunition designed to handle demanding backcountry and remote hunting conditions without sacrificing reliability or stopping power. The 338 Winchester Magnum chambering delivers the velocity and energy needed for larger game, while the lead-free construction makes it legal in California and other regions with ammunition restrictions.
What sets Outfitter ammo apart is the engineering behind corrosion resistance. Nickel-plated cases protect against moisture and rust—critical when you're hunting in rain, snow, or high-humidity terrain where conventional brass degrades fast. The sealed primer and case mouth create a watertight barrier, so your rounds stay dry and functional even in wet rucksack conditions or extended field trips. That's the difference between ammo you can trust and ammo that sits in your pack wondering if it'll fire when it matters.
The GMX bullet itself is a monolithic design that cuts no corners. Uniform, controlled expansion paired with deep penetration and over 95% weight retention means energy transfer is predictable—you get reliable performance on target without bullet fragmentation or dramatic energy loss. For hunters pursuing larger game in the 338 Win Mag range, that consistency translates to ethical, effective kills. This is ammunition built for the hunter who respects the hunt and the animal, not the shooter chasing hype.
Twenty rounds per box keeps you supplied for a serious hunt or range session without excessive bulk. Load up with confidence.
