What is .14-222 cartridge?

Sorry, as an AI language model, I don't have access to external data or browse the web. However, I can tell you that the cartridge designations in the format ".XX-YYY" usually refer to the caliber (XX) and the powder charge (YYY) of the ammunition. Without any context, it is impossible to determine which particular firearm or application the .14-222 cartridge is intended for.
