The .33 Winchester Center Fire (colloquially .33 WCF^[1] or .33 Win) is an American centerfire rifle cartridge.

History[]

Introduced by Winchester for the Model 1886 lever rifle in 1902, it survived until the Model 86 was dropped in 1936.^[2] It was also offered in the Marlin Model 1895 and Winchester's own single-shot Model 1885.^[2]

The .33 WCF cartridge.

Use[]

A good round for deer, elk, or black bear in wooded terrain at medium range, it out performs the ballistically similar .35 Remington and can be improved with modern powders.^[2] The .33 WCF was replaced by the more powerful .348 Winchester and stopped being commercially offered in 1940.^[2]
