• Source: .338 Ruger Compact Magnum

The .338 Ruger Compact Magnum or .338 RCM is a rimless, short-length rifle cartridge based on the .375 Ruger case. Sturm Ruger and Hornady jointly developed the round, which was released in 2008 and chambered in various Ruger rifles. The goal of the project was to produce a .338 caliber cartridge with magnum level performance that would fit in a compact, short action rifle. The .338 RCM is conceptually similar to the WSM cartridge family, but is somewhat smaller dimensionally. This often allows for a higher magazine capacity than the WSM equivalent. Like the .338 caliber cartridges which predated it, the round is designed for hunting medium to large sized North American game.




Design & Specifications


The .338 Ruger Compact Magnum is based on the .375 Ruger cartridge, which originated through the cooperation of Hornady and Ruger. The case is of rimless design, having a base and rim diameter of .532 in (13.5 mm), the same diameter as the belt on the .300 H&H Magnum, the .375 H&H Magnum, and their derivatives. This design offers greater case capacity than a belted magnum case of comparable length, such as the 350 Remington Magnum. As Ruger intended the cartridge to be chambered in short bolt-action rifles, they trimmed the .375 Ruger parent case to 2.015 in (51.2 mm) to ensure a comparable cartridge overall length to the .308 Winchester. Unlike the rebated Winchester Short Magnum cartridges, the Ruger Compact Magnums share the same diameter from case head to body. This allowed Ruger to chamber the cartridge without extensively redesigning their M77 rifle.
