Norma Magnum

The .30-338 is a wildcat cartridge formed by necking the parent .338 Winchester Magnum case down to .30 caliber. The fondness of U.S. shooters for cartridges that will function in the various rifles normally used in high-power competition prompted the development of this cartridge.

The somewhat shorter case of the .30-338 wildcat permits seating bullets further out than the .300 Winchester Magnum, its closest competitor in long-range competition. The velocities obtained with these two cartridges are nearly identical.

The .30-338 is almost an identical twin to the .308 Norma Magnum and this loading data is considered suitable for that cartridge.

There is no SAAMI pressure limit for the .30-338 cartridge. 65,000 P.S.I. was accepted as the pressure limit for the cartridge based on its cartridge case and the pressure limits of other cartridges in its class. This is a wildcat cartridge with potentially a great deal of variation in the various rifles chambered for it. Care should be exercised in approaching the maximum loads listed here.
