What is 338 rcm?

The .338 RCM (Ruger Compact Magnum) is a rifle cartridge developed by Sturm, Ruger & Co. in collaboration with Hornady. It was introduced in 2008 as a high-performance, short-action cartridge designed for big game hunting.

The .338 RCM is based on the .375 Ruger case necked down to .338 caliber. It offers significantly higher velocities and greater energy levels compared to other standard .338 cartridges, such as the .338 Winchester Magnum and .338 Lapua Magnum.

With a moderate recoil and flat trajectory, the .338 RCM is suitable for hunting medium to large game at long distances. It delivers excellent terminal ballistics and is effective for hunting animals like elk, moose, and bear.

Overall, the .338 RCM is a versatile cartridge that offers a good balance of power, accuracy, and manageable recoil for hunters looking for a high-performance round in a compact rifle platform.
