The 4.5mm mkr cartridge was developed by Interdynamics AB, a Swedish company, in the 1980s. It was essentially a .22 WMR necked down to a 4.5mm bullet, designed to be used in the Interdynamics MKR rifle.
Due to concerns about stopping power and problems with using rimfire ammunition the MKR project was abandoned at the prototype stage and thus the 4.5mm mkr never saw service or any kind of widespread use.
