The .375 Remington Ultra Magnum, also known as the .375 RUM is a .375 rifle cartridge introduced by Remington Arms in 2000. The cartridge is intended for large and dangerous game.
It is a beltless, rebated rim cartridge created by necking up the .300 Remington Ultra Magnum case to .375 caliber with no other changes. Factory loadings are less powerful than handloads for the cartridge. Remington factory loads produce 2,760 ft/s (840 m/s)http://remington.com/products/ammunition/centerfire/premier-a-frame/premier-a-frame.aspx PREMIER A-FRAME Remington Remington Arms Company, LLC 870 Remington Drive P.O.

General information
The intended use of this cartridge includes hunting large, thick-skinned game. It is powerful enough to kill any land animal and, with its high velocity, can do so at fairly long ranges. Such performance comes at the price of a heavy recoil: in a sporting-weight rifle of ~8 lb (3.6 kg), this cartridge can produce a fierce 80 ft·lbf (108 J) of recoil (approximately 3.5 times that of a .30-06.)
There is a wide selection of .375 in (9.53 mm) bullets available that are suited to the high velocities of the .375 RUM, and boat tail bullets help to further extend the useful range.March 2025
