The foregoing information is correct. It is also often called the .43 Mauser, as used in the M71 and M71/84 Mauser bolt action rifles. Some of those rifles remained in limited military service as late as during WWI.
I have owned several of them, but it was long ago. Back then it was fairly easy to find Canadian C-I-L loaded ammunition and brass to reload. They may have been the last good source of supply. I still have a Portuguese Kropatschek rifle which is essentially a M71/84 rifle but chambered in 8mm caliber.
