The .375 Remington Ultra Magnum, also known as the .375 RUM is a .375 rifle cartridge introduced by Remington Arms in 2002. It is a beltless, rebated rim cartridge created by necking up the .300 Remington Ultra Magnum case to .375 caliber with no other changes. The .375 Remington Ultra Magnum is second only to the .378 Weatherby Magnum in cartridge-case capacity. Factory loadings are strong, but relatively sedate when one considers the true potential of the cartridge. Remington factory loads push a 300 grain (19 g) bullet at 2760 ft/s (840 m/s), producing 5070 ft·lbf (6.88 kJ) of energy. A handloader can increase the muzzle velocity of this bullet to a maximum of 2950 ft/s (900 m/s,) developing 5800 ft·lbf (7.9 kJ).
