Mnhunter, your Winchester Model 1894 was made in 1897.
The .30 WCF and .30-30 Win. are the same cartridge. IIRC, the .30 WCF caliber designation was used with the 1894 Model. When the Model 94 was introduced the caliber designation changed to .30-30 Win. but they are the same cartridge. Hope this helps!
