The .358 Norma Magnum gained popularity in the United States after the Swedish ammunition manufacturer Norma Precision introduced this high-powered .35-caliber hunting cartridge in 1959. Highly regarded among Big Game Hunters and Handloaders, the .358 Norma Magnum is known for delivering magnum-level performance with 200 and  250-grain bullets, offering muzzle energy and downrange stopping power comparable to the legendary .375 H&H Magnum. This cartridge is a favorite for custom rifle builds, precision reloading, and long-range hunting of moose, elk, bear, and African plains game, thanks to its flat trajectory, excellent sectional density, and deep-penetrating bullet performance when using premium reloading components such as brass cases, large rifle magnum primers, and slow-burning powders like H4831 or IMR 4350.
