The term "18r" typically refers to a specific type of rifle cartridge, specifically the .18 Remington, which is a centerfire cartridge designed for small to medium game hunting. It is known for its flat trajectory and relatively low recoil, making it suitable for varmint hunting. The "r" in "18r" usually stands for "Remington," indicating the manufacturer associated with the cartridge.
Missouri Game Regualtions appear only to require that it be a centerfire cartridge. However, I would encourage you NOT to try this- the 9mm simply does not have enough power for a clean kill.
