.358 Norma Magnum
Rifle cartridge / From Wikipedia, the free encyclopedia
The .358 Norma Magnum is a rifle cartridge introduced in 1959 by Norma. The cartridge is closely related to the .308 Norma Magnum and both cartridges share the same case head dimensions as the .300 H&H Magnum, but have far less body taper, resulting in the same internal capacity in a shorter case.[1] The cartridge case is the longest that will comfortably fit in a standard Mauser action, or any rifle action designed to chamber the .30-06. The .358 NM was the first .35 caliber cartridge commercially developed and sold to the American market since the decline of the .35 Newton in the late 1920s.
