Cartridge History
The .500 Weatherby is a specialized custom or wildcat chambering associated with the Weatherby magnum case family. It should not be confused with Weatherby's standardized .460 Weatherby Magnum or treated as a current Weatherby factory cartridge without documentation from the rifle builder.
Rifles and Platforms
- Custom rifles specifically chambered and marked for .500 Weatherby
- Large magnum actions built around the individual reamer and die specification
Compatibility warning: Non-standardized custom or wildcat chamber; use the exact rifle builder's reamer, dies, and loading specifications Similar names, shared parent cases, or matching caliber alone do not establish interchangeability.
Did You Know?
Weatherby's current factory cartridge lineup centers on the standardized .460 Weatherby Magnum; a rifle marked .500 Weatherby requires its own chamber documentation.
