.300 Remington Ultra Mag (RUM) 200 Grain Hornady ELD-X- The .300 Remington Ultra Magnum is one of the largest commercially available .30 caliber magnums currently being produced. It is a beltless, rebated rim cartridge, capable of handling all large North American game, as well as long-range shooting. Among commercially produced .30-caliber rifle chamberings, the .300 Remington Ultra Magnum is second only to the .30-378 Weatherby Magnum in cartridge-case capacity.
The .300 Remington Ultra Magnum is a member of the Remington Ultra Magnum cartridge family based on the .404 Jeffery via the Canadian Magnum cartridges. As these cartridges feature wider bodies than the belted magnums based on the .375 H&H case, these cartridges have greater case capacities than their corresponding full length belted Magnum cartridges such as the 7 mm Shooting Times Westerner, the .300 Weatherby Magnum, .340 Weatherby Magnum and the .375 Ackley Improved. The .300 RUM is an excellent long range cartridge with the ability to deliver a useful level of energy downrange especially with the power level III ammunition. Due to its high velocity it exhibits less bullet drop than most other .30 caliber (7.62 mm) cartridges.
Compared to other production .30 caliber (7.62 mm) cartridges, only the .30-378 Weatherby Magnum surpasses the .300 Remington Ultra Magnum.

The Heat Shield tip of the Hornady ELD-X bullet defies the effects of aerodynamic heating and retains its shape to provide a perfect meplat (tip) that is always the same shape. A streamlined secant ogive with optimum boattail design, plus the highly concentric AMP bullet jackets, combined with the patent pending Heat Shield tip creates a supremely accurate, high BC match bullet. ELD-Match bullet BCs are measured with Doppler radar and corrected to standard atmospheric conditions. With high velocity, 0-400 yard impact, the bullet continually expands throughout its penetration path. The thick shank of the jacket and high Interlock ring keep the core and jacket together providing 50-60% weight retention. Upon low velocity, 400+ yard impacts, the Heat Shield tip drives backward into the bullet to initiate expansion. Exhibiting conventional expansion with a large mushroom and 85-90% retained weight the bullet provides deep penetration and large wound cavities.
