  • The .338 Blaser Mag is a rifle cartridge developed by the German firearms manufacturer Blaser in 2008. It was designed as a high-powered cartridge for long-range hunting and shooting.

    The cartridge is based on the .416 Rigby 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 2.8 inches.

    The .338 Blaser Mag is capable of firing bullets weighing between 200 and 300 grains at muzzle velocities ranging from 2,900 to 3,200 feet per second. It is a highly accurate cartridge that is favored by long-range hunters and shooters who need to take shots at extended ranges.

    The cartridge has a flat trajectory and delivers a high amount of energy to the target, making it suitable for hunting large game animals, such as elk, moose, and brown bear. It is also used for long-range target shooting and has been used to set records in long-range shooting competitions.
