- The .300 RCM (Remington Compact Magnum) is an incredibly powerful shell, developed in 2007 for use in short-action rifles. This round combines the velocity and energy of a magnum rifle cartridge with increased accuracy potential - making it perfect for both hunting dangerous game animals out to extreme distances as well as serious target shooting competitions.Offering superior accuracy potential from quality rifles equipped with optics, this rifle round is capable of taking down even the largest game animals out to ranges beyond what most other magnums are capable of delivering - while retaining sufficient power to penetrate through thick hides and bone. Its unflagging performance across temperatures and atmospheric conditions makes it ideal for shooters looking for consistent precision at extended distances.
