.308 Norma Magnum

The .308 Norma Magnum cartridge was created by Norma of Sweden. It is a .338 Winchester Magnum case necked down to .308. While it appeared to have a bright future initially, it was soon superseded in popularity by the .300 Winchester Magnum.

Cases for the cartridge can be purchased from Norma or made in three ways: Necking up a 7 mm Remington Magnum case, necking down a .338 Winchester Magnum case, or running .300 Winchester Magnum cases through a full-length sizing die. Since the first two options leave the brass a bit short, the third is generally considered to be the best option. Ammunition for this caliber is not cheap (typically US$50–60 for 20 cartridges) and as such it is mainly of interest only to handloaders who own a rifle chambered in this caliber. The cartridge makes use of a belted case for strength.
