The .300 Remington Ultra Magnum was built for distance, and this Hornady load delivers the precision to match that capability. The 220-grain ELD-X bullet cuts through the wind at 2910 fps with 4136 ft-lbs of muzzle energy, offering the flat trajectory and energy retention that makes this cartridge popular for elk and larger game at extreme ranges.
Most polymer-tipped bullets deform under the aerodynamic heat generated during high-speed flight, particularly beyond 400 yards. Hornady's engineers solved this with the Heat Shield tip, a heat-resistant polymer compound that maintains its shape throughout the entire trajectory. The consistent tip geometry translates directly to better in-flight stability and retained ballistic coefficient at distance where it matters most. Combined with the advanced manufacturing process (AMP) jacket and boattail design, the result is a bullet that stays true from the muzzle all the way downrange.
The ELD-X is engineered to expand reliably whether you're shooting a 100-yard shot at close quarters or stretching it to 600 yards or beyond. At conventional ranges up to 400 yards, the thin nose section peels back progressively while the InterLock ring holds the core and jacket together, delivering 50 to 60 percent weight retention. On longer-range shots where velocity drops, the Heat Shield tip drives backward into the bullet to initiate expansion, providing 85 to 90 percent weight retention and deeper penetration. This dual-performance design means you're not compromising terminal ballistics regardless of distance.
These rounds are loaded to uniform capacity with clean-burning powders and matched primers, the kind of attention to detail you'd expect from match ammunition but rarely find in factory hunting loads. That consistency translates to shot-to-shot velocity uniformity across temperature extremes, building the accuracy confidence you need when hunting becomes real.
Standard polymer tips melt and deform in flight at high velocities, especially beyond 400 yards, which reduces ballistic coefficient and accuracy. The Heat Shield tip is made from a heat-resistant polymer with a much higher melting point that maintains its shape throughout the entire trajectory. This keeps the bullet's ballistic coefficient consistent and accuracy sharp from close range to extended distances.
Yes. The 220-grain bullet weight paired with the .300 RUM's velocity makes this an excellent choice for elk, moose, and similar large game at long range. The ELD-X design provides consistent expansion across all practical hunting distances, delivering the terminal performance necessary for ethical kills. This load is considered one of the best all-around options for .300 RUM hunting.
The .300 RUM is effective well beyond 1000 yards from a ballistics standpoint, but ethical hunting typically stays within 600 yards depending on your rifle, optics, and shot placement. The ELD-X bullet maintains enough velocity and energy at these ranges to deliver reliable expansion and terminal performance on large game.
Yes. These rounds come loaded in factory-new brass cases with standard large rifle magnum primers, making them fully reloadable. Save your brass for reloading since the .300 RUM is a larger magnum case where component costs add up.
