Load data for caliber ".358 Norma Mag."
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.

The Commission internationale permanente pour l'épreuve des armes à feu portatives ("Permanent International Commission for the Proof of Small Arms" – commonly abbreviated as C.I.P.) is an international organisation which sets standards for safety testing of firearms. (The word portatives ("portable") in the name refers to the fact the C.I.P. tests small arms almost exclusively; it is ordinarily omitted from the English translation of the name.) As of 2015, its members are the national governments of 14 countries, of which 11 are European Union member states. The C.I.P. safeguards that all firearms and ammunition sold to civilian purchasers in member states are safe for the users.
To achieve this, all such firearms are first proof tested at C.I.P. accredited Proof Houses. The same applies for cartridges; at regular intervals, cartridges are tested against the C.I.P. pressure specifications at the ammunition manufacturing plants and at C.I.P. accredited Proof Houses.
