What is 338 rcm?

.338 Ruger Compact Magnum (.338 RCM)

The .338 Ruger Compact Magnum, often abbreviated as .338 RCM, is a short, magnum rifle cartridge designed for hunting medium to large game. It was a joint development by Ruger and Hornady, introduced in 2006, with the goal of providing near .338 Winchester Magnum performance in a shorter action rifle.

• Design Goals: The primary goal was to achieve .338 Winchester Magnum performance in a more compact and lighter rifle platform. This was accomplished by using a shorter, fatter cartridge case. This allowed for use in standard or short-action rifles, making them easier to carry and maneuver in dense hunting environments.

• Performance: The .338 RCM delivers excellent ballistics for its size. It typically pushes a 225-grain bullet at around 2,800 feet per second. This provides a flat trajectory and significant energy on target, making it suitable for game such as elk, moose, bear, and similar large animals at reasonable hunting distances.

• Cartridge Dimensions: Its case is shorter than the .338 Winchester Magnum, which is what enables it to fit into shorter actions. This also means it has a smaller powder capacity.

• Advantages:

  • Compactness: Shorter action rifles are generally lighter and easier to handle.
  • Recoil: While still producing significant recoil, it is generally perceived as less than the .338 Winchester Magnum in comparable rifles due to the slightly lower velocity.

• Disadvantages:

  • Availability: Ammunition and rifles chambered in .338 RCM can be less common and thus possibly more expensive compared to more popular cartridges like the .30-06 Springfield or .300 Winchester Magnum, especially in certain regions.
  • Performance vs. .338 Win Mag: While designed to mimic .338 Winchester Magnum performance, the .338 RCM typically falls slightly short, particularly with heavier bullet weights, due to reduced powder capacity.

• Typical Uses: Primarily intended for hunting medium to large game at moderate to long ranges. It's a good choice for hunters who value portability and maneuverability in their rifles. Important subjects:
