About 338 Rem Ultra Mag
The .338 Remington Ultra Magnum (RUM) is a high-powered, long-range rifle cartridge introduced by Remington in 2002.
It was developed by necking up the .300 Remington Ultra Magnum case to .338 caliber, offering a hard-hitting round designed to compete with other large-caliber, high-velocity cartridges like the .338 Lapua Magnum.
Known for its flat trajectory and exceptional energy retention, the .338 RUM is widely used for big game hunting, making it an excellent choice for hunters pursuing elk, moose, and other large North American game at extended distances.
Additionally, its ballistic performance makes it a capable option for long-range precision shooting, though it is less common in military and tactical applications compared to the .338 Lapua.
