When Normaintroduced the .358 Magnum in 1959, it was the first commercially loaded .35 caliber magnum made available to American hunters since the .35 Newton had bit the dust in the late 1920's. The .358 Norma Magnum is an extremely powerful cartridge with ballistics quite close to that of the famed .375 H&H; Magnum. Had Winchester not introduced its .338 Magnumin 1958, the .358 Norma might now be one of our more popular cartridges. Although the .358 Norma Magnum is a bit much for hunting deer size game, the 200 grain Hornadyand Remingtonspire points, and the 225 grain bullets available from Noslerand Sierraare good choices for this purpose. For all around use on moose and elk, the Speerand Hornady250 grain bullets are better medicine. As a brown bear cartridge, the big .358 is probably seen at its best when loaded with the Nosler225 grain Partition, the Speer250 grain African Grand Slam, or the BarnesX-Bullet in its heaviest weight. H4350 is an excellent .358 Magnum powder, as are H414, Reloader-19, W-760, and IMR-4350.
