  • The .338 Remington Ultra Magnum (RUM) is a rifle cartridge developed by Remington Arms in 2000. It was designed as a high-velocity, long-range cartridge that would offer the power and accuracy needed for hunting and long-range shooting.

    The cartridge is based on a modified .404 Jeffery case, which was necked down to accept .338 caliber bullets. The resulting cartridge has a bullet diameter of .338 inches and a case length of 2.825 inches.

    The .338 RUM is capable of firing bullets weighing between 180 and 300 grains at muzzle velocities ranging from 2,900 to 3,200 feet per second. It is a powerful cartridge that is suitable for hunting a wide range of game animals, including elk, moose, and brown bear, at long ranges.

    One of the main advantages of the .338 RUM is its long-range accuracy, which makes it popular among long-range shooters and hunters. It is also known for its flat trajectory, which makes it easier to shoot accurately over long distances.
