The Hornady Outfitter 300 Remington Ultra Magnum 180gr CX lead-free rifle ammunition brings field-proven reliability to hunters and long-range shooters who demand performance in unforgiving conditions. Built around Hornady's monolithic copper alloy GMX bullet, this load delivers the controlled expansion and deep penetration you need for clean, ethical kills on medium to large game while meeting lead-free ammunition requirements in California and other restricted regions. Each 20-round box is engineered to protect your investment and your hunt, with nickel-plated cases and sealed primers that keep moisture and corrosion out when you're glassing ridges, crossing water crossings, or waiting out weather in the field.

The 180-grain weight in the 300 RUM gives you velocity, energy, and bullet mass for shots at distance—ideal for open-country hunting where long-range precision matters. The GMX bullet's monolithic construction means no jacket-core separation under impact; Hornady documents over 95% weight retention, which translates to deeper, more consistent penetration than traditional lead-core designs. That's not marketing language; it's material science that matters when your tag is on the line.

Whether you're a hand-loader who values case quality or a hunter who loads factory ammunition and expects it to work the first time and every time, the Outfitter line respects the reality of backcountry hunting: gear gets wet, temperatures swing, and ammunition sits in packs for months. The watertight case mouth and sealed primer are small details that prevent the kind of failures that cost you an opportunity. California hunters and those in other regions with strict non-traditional ammunition mandates will appreciate that this load is built from the ground up to comply while sacrificing nothing in field performance.
