The .300 Remington Short Action Ultra Magnum (.300 Rem SAUM) is a high-performance, short-action rifle cartridge introduced by Remington Arms in 2002. It was designed as a compact alternative to the full-length magnum cartridges, offering impressive ballistics and performance in a shorter, more efficient package. The .300 Rem SAUM is well-suited for hunting a wide range of game, from medium-sized animals like deer and antelope to larger species such as elk and moose, at various distances.
The .300 Rem SAUM features a rebated rim bottleneck case with a large powder capacity, enabling it to drive .30 caliber (7.62mm) bullets at high velocities while maintaining a relatively short overall length. The cartridge typically accommodates bullet weights ranging from 150 to 200 grains, with muzzle velocities between 2,900 and 3,200 feet per second, depending on the bullet weight and powder charge.
One of the main advantages of the .300 Rem SAUM is its ability to provide near magnum-level performance in a compact, short-action rifle platform, allowing for faster cycling and potentially lighter rifle weight. The cartridge delivers a flat trajectory, good accuracy, and excellent energy retention, making it suitable for hunting applications across a wide range of distances.
The .300 Remington Short Action Ultra Magnum is an excellent choice for hunters and shooters who want a powerful, versatile cartridge that can be used in a short-action rifle without sacrificing performance. Though it may not be as popular as some of the other .30 caliber options, the .300 Rem SAUM remains a capable and effective choice for those seeking a compact, high-performance hunting cartridge.
