- The .358 Norma Magnum is a rifle cartridge that was developed by the Swedish company Norma in 1958. It is based on the .338 Norma Magnum cartridge and uses a necked-up case to accept .358-inch diameter bullets.
The .358 Norma Magnum cartridge is designed to provide high velocity and energy, making it suitable for hunting medium to large game at long ranges. It is capable of producing velocities of up to 3,000 feet per second and can deliver over 4,000 foot-pounds of energy at the muzzle.
Despite its excellent ballistics, the .358 Norma Magnum cartridge is not as widely used as some other magnum rifle cartridges such as the .300 Winchester Magnum or the .338 Lapua Magnum. It may be more difficult to find ammunition and firearms chambered for this cartridge, but it has a dedicated following among hunters and long-range shooters who appreciate its performance and accuracy.
