.300 Remington Ultra Mag (RUM) 190 Grain Lead Free Barnes LRX- 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 Long-Range X Bullet (LRX) line is designed after the best-selling Tipped Triple-Shock X Bullet, the LRX bullet design increases Ballistic Coefficient values by increasing ogive and boat tail lengths to improve the bullets’ long-range ballistic performance. For the hunter who is confident in long-range hunting, the LRX will fill the niche of this new hunting craze. LRX bullets will continue to be manufactured with the proven 100-percent copper, lead-free bodies. The bullet’s polymer tip initiates expansion, causing the nose cavity to open instantly on contact doubling the bullet’s original diameter while creating four cutting petals that wreak extensive internal damage. Exceptional performance means clean, quick kill.
