.338 RCM

The .338 RCM (Ruger Compact Magnum) is a rifle cartridge developed by Sturm, Ruger & Co. in 2008. It was designed as a short-action cartridge that would offer the power of larger cartridges like the .338 Winchester Magnum in a shorter, lighter rifle.

The cartridge is based on the .375 Ruger case, which was necked down to accept .338 caliber bullets. The resulting cartridge has a bullet diameter of .338 inches and a case length of 2.015 inches.

The .338 RCM is capable of firing bullets weighing between 200 and 225 grains at muzzle velocities ranging from 2,800 to 2,900 feet per second. It is a powerful cartridge that is suitable for hunting a wide range of game animals, including elk, moose, and brown bear.

One of the main advantages of the .338 RCM is its compact size, which makes it ideal for use in lightweight, short-action rifles. It also has a relatively low recoil compared to larger cartridges like the .338 Winchester Magnum, which makes it more comfortable to shoot for some hunters and shooters.

The .338 RCM has gained a following among hunters and shooters who appreciate its combination of power, accuracy, and compact size. It is typically chambered in bolt-action rifles, and a number of firearms manufacturers produce rifles that are chambered for the .338 RCM cartridge.

While the .338 RCM is not as widely available as some of the more established cartridges on the market, it has a dedicated following and is available from a number of firearms manufacturers. It is also relatively affordable compared to some of the larger, more specialized cartridges.
