What is .375 rum?

The .375 Rum is a high-powered rifle cartridge developed by Remington Arms in 2000. It is based on a shortened and necked-down version of the .404 Jeffery case, with a bullet diameter of .375 inches. The cartridge is designed for long-range hunting, with a high velocity and flat trajectory. The .375 Rum can shoot bullets weighing between 235 and 300 grains, and has a muzzle velocity of up to 3,250 feet per second. It is considered one of the most powerful non-magnum cartridges available, and is ideal for hunting big game, such as elk, moose, and brown bear.
