Who This Is For
This ammunition is built for serious big-game hunters pursuing elk, moose, bear, or other large and dangerous species at extended ranges. If you're heading into backcountry where weather is unpredictable and a second shot isn't guaranteed, the Hornady Outfitter 300 RUM 180 GR CX gives you the confidence to take the shot when it counts. It's equally at home on guided hunts in wet coastal rainforests or high-altitude alpine settings where reliability and terminal performance are non-negotiable.

Frequently Asked Questions
What makes the CX bullet better than a traditional lead-core bullet for hunting?
The CX (Copper Alloy eXpanding) bullet is a monolithic design, meaning it has no separate lead core that can separate from the jacket on impact. Instead, it expands uniformly through a polymer tip and precisely engineered grooves, achieving over 95% weight retention. This results in deeper, straighter wound channels and more reliable terminal performance on large or heavily boned game — especially at the high velocities generated by the 300 RUM.
Is this ammunition suitable for long-range shots on elk or moose?
Yes. The 300 RUM is one of the most powerful commercially available rifle cartridges, and paired with Hornady's 180-grain CX bullet, it retains exceptional velocity and energy well past 400 yards. The high ballistic coefficient helps resist wind drift, making it an excellent choice for hunters who may face long cross-canyon or open-meadow shots on large North American big game.
Why does Outfitter ammunition use a sealed primer and case mouth?
The sealed primer and case mouth are designed to prevent moisture intrusion during field use — whether you're fording streams, hunting in heavy rain, or carrying rounds loose in a wet jacket pocket. This weatherproofing ensures reliable ignition even when cartridges have been exposed to wet conditions, giving you one less variable to worry about in critical moments afield.
