History
Introduced by Winchester for the Model 65 rifle in 1938. Based on the .25-20 WCF case necked to .22. Offered noticeably better performance than .22 Hornet but was orphaned when Remington's 1950 .222 Remington made it redundant. Still chambered occasionally in single-shots and lever actions.
