The .30-378 ammo Weatherby Magnum is a .30 caliber, belted bottle-necked rifle cartridge. The cartridge was developed in response to a US Army military contract in 1959.

The .30-378 was originally designed by Roy Weatherby as an anti-personnel / anti-materiel military cartridge for a government contract. The .30-378 Weatherby Magnum is one of the most accurate rifle cartridges.

The .30-378 Weatherby Magnum utilizes the .378 Weatherby Magnum as a parent cartridge. The .378 Weatherby case was necked down to accept a .30 caliber (7.62 mm) bullet while preserving the double radii shoulder of the parent case.
