The .300 Ultra Magnum, also known as the .300 Remington Ultra Magnum or .300 RUM, is a powerful rifle cartridge designed for long-range hunting and shooting. It was developed by Remington Arms Company in 1999 and is based on a necked-down .404 Jeffery case.

The .300 Ultra Magnum is known for its high velocity and flat trajectory, making it an excellent choice for long-range shooting and hunting large game such as elk, moose, and bear. It has a reputation for delivering excellent accuracy and performance at extended ranges.

The cartridge has a maximum overall length of 3.60 inches and uses a large rifle magnum primer. It typically fires a 180 to 220 grain bullet at velocities exceeding 3,000 feet per second, making it an extremely powerful and capable round for long-distance shooting.

Overall, the .300 Ultra Magnum is a popular choice among long-range shooters and hunters who require a high-powered cartridge with excellent performance at extended ranges. However, it does produce significant recoil and muzzle blast, so it may not be the best choice for novice shooters or those sensitive to recoil.
