The 22 Hornet and 5.6x35 both come from the 22WCF.When the Hornet was commercialized,it had a velocity of 2400 fps with higher pressures than the 22WCF.To prevent being used in the black powder rifles, the rim was thickened so it wouldn't chamber.The 22WCF was also popular in Germany,under it's American name.When it was loaded with smokless powder and jacketed bullet, it was loaded to about 2000fps and called 5.6x35R Vierling.The rim was not thickened like the Hornet.The case length of the 5,6x35R Vierling is 35.50mm, while the Hornet is 35.64mm. The Germans usually call the Hornet "22 Hornet", but when called by it's metric designation, it's the 5.6x36R.
