The .30 Newton cartridge was designed by Charles Newton for Fred Adolph, a gunsmith, in 1913, and was originally known as the .30 Adolf Express. The Newton Arms Company was the only manufacturer of commercial rifles chambered for this cartridge. It should not be confused with the .30 Belted Newton (a.k.a. .30-338), which is a different cartridge not designed by Charles Newton. Although suitable for any large North American game, it is an obsolete round no longer manufactured. Before WWII, loaded cartridges were once offered by Western Cartridge Company. Buffalo Arms currently sells unloaded brass.
