The .375 Remington Ultra Magnum (RUM) is a high-power rifle cartridge designed by Remington Arms. Introduced in 2000, it is part of Remington's Ultra Magnum series, known for its high velocity and significant energy. The .375 RUM is based on the .404 Jeffery case but modified to achieve higher performance.
Specifications:
- Bullet diameter: .375 inches (9.5 mm)
- Case length: 2.850 inches (72.4 mm)
- Overall length: 3.600 inches (91.4 mm)
The .375 RUM is capable of firing bullets weighing between 200 and 350 grains at muzzle velocities exceeding 2,500 feet per second (fps), making it suitable for hunting large and dangerous game, such as African big game (elephants, Cape buffalo) and large North American game (bears, moose). Its high velocity and energy provide excellent penetration and stopping power.
Given its power, the .375 RUM also generates significant recoil, which may be challenging for some shooters to manage. It's primarily used by experienced hunters who need a cartridge capable of taking down large and potentially dangerous animals at various distances. This cartridge is less commonly used for target shooting due to the recoil and cost of ammunition.
