Performance

Remington ammunition for the .300 RUM is available in three Power Levels. Power Level I duplicates the .30-06 Springfield, Power Level II that of the .300 Winchester and Power Level III is the full power load. Remington offers the full power (Power Level III) .300 Remington Ultra Magnum ammunition in 150 gr (9.7 g) at 3,450 ft/s (1,050 m/s), the 180 gr (12 g) at 3,250 ft/s (990 m/s) and the 200 gr (13 g) at 3,032 ft/s (924 m/s). These are among the highest velocities attained by a .30 caliber production rifle cartridge

The .300 RUM is an excellent long range cartridge with the ability to deliver a useful level of energy downrange especially with the power level III ammunition.. Due to its high velocity it exhibits less bullet drop than most other .30 caliber (7.62 mm) cartridges.

SAAMI recommends that the barrel have a 6 groove contour with a twist rate of one revolution in 10 in (250 mm). The barrel is to have a groove width of .115 in (2.9 mm). Bore is given as .300 in (7.6 mm) and a groove is .308 in (7.8 mm). Maximum case overflow capacity is 122.5 gr. of water (7.30 cm3). SAAMI recommended Maximum Average Pressure is set at 65,000 psi (4,500 bar).

Remingtons ultra magnum cases were made wider than the .404 Jeffery case by .006 in (0.15 mm). The brass was made thicker so as to withstand the higher pressure of the new cartridge as the Jeffery cartridge had a maximum average pressure rating of 3,650 bar (52,900 psi)
