Is a 308 Winchester different from a 308 Weatherby?

Answer 1

There is no such cartridge as a ".308" weatherby, only a .308 Winchester, interchangable with the 7.62 Nato. Once upon a time, Weatherby only made rifles in unique weatherby cartridge calibers, eg. .300 weatherby, .378 weatherby, .460 weatherby, etc. Now weatherby makes rifles in many non-weatherby cartridge calibers, including the .308 Winchester. Do not confuse a rifle manufacturer with the company name that may have introduced the cartridge in which the rifle may be chambered. To further get your head spinning, many cartridge companies make cartridges (all equivalent) in the .308 Winchester caliber including Winchester, Remington, federal, norma, and multiple European companies.

The short answer is yes they are the same. If you see a weatherby rifle chambered in .308, (and not .308 Norma Magnum), it is a .308 Winchester caliber (Winchester rifles exist in .308 Winchester caliber).

The weatherby rifle is most likely a weatherby 'Vangard' model (a cheaper line of rifles manufactured by weatherby). Top of the line weatherby model rifles are noted for their high prices, ornate stocks and high power weatherby calibers (the .460 weatherby magnum is the most powerful factory cartridge in the world, about 80% more muzzle energy than the .458 Winchester magnum, first sold in Winchester's African model 70 rifle).
