The .378 Weatherby Magnum dates to 1953, when Roy Weatherby sought a significant power improvement over the .375 Holland & Holland and the .375 Weatherby. The basic H&H case was the fattest, longest case used for American rifle cartridges at the time, but Weatherby needed more.

The new cartridge was named the .378 Weatherby Magnum and was introduced to the public as a Weatherby proprietary cartridge in 1953. Up until the creation of the .375 CheyTac (post 2002), the .378 Weatherby was the world's most powerful .375 caliber cartridge. This cartridge was also used as Weatherby's base for the design of the .460 ...
The .338-378 Weatherby is currently the most powerful .338" factory cartridge. In a similar manner to the .338 Lapua, the .338-378 employs a full .579" diameter case rim rather than a standard magnum rim diameter of .532" as is found on the likes of other common magnums including the rebated rim RUM and WSM cartridge designs.

The .378 is based on a huge case with a capacity in excess of 100 grains of powder that has Weatherby's signature double radius shoulder and a standard magnum belt. Despite its unusual nomenclature, the .378 uses standard .375" bullets. The factory ballistics for the .378 Weatherby are impressive, to say the least.
Designed to replace the 375 Weatherby Magnum, deep penetration and bone smashing power are the calling cards of the 378. Its massive case holds so much powder that Federal designed its super-hot 215 primer to handle the load. Roy Weatherby's 378 delivers 34 percent more energy at the muzzle than the powerful 375 H&H Magnum.
The .30-378 can be loaded with light 130 to 150 grain bullets as is found in Weatherby factory ammunition (130 grain Barnes) but problems can occur. The twist rate of Weatherby rifles (and custom rifles) is 1:10, suitable for projectiles weighing 165 grains and heavier. In lower powered cartridges, 1:10 twist bores will adequately stabilize ...
