When did the WCF 30 Cal become 30 30?

Answer 1

The 30 WCF was introduced with the model 94 in 1894 and hit resistance in the market place because customers were used to purchasing rifle ammunition with two numbers. The first number was the caliber and the second number was the grains of black powder loaded in the cartridge. Since the 30 WCF was a smokeless powder round, Winchester saw no reason to use a black powder designation on the name until the market place rejected it. It was quickly renamed .30-30 (the actual components being used were unchanged, of course) and the rifle and ammunition became very successful. This occurred around 1895 or 1896.
