c. 8mm Mauser Information 
by A. R. Campbell () 
Names 
8mm Mauser cartridges use .323 inch (7.92mm) diameter bullets. US-made commercial ammo in this 
caliber will usually be labelled either "8mm Mauser" or "8x57". Foreign-produced ammo and military 
ammo in this caliber is called by several other names depending on the manufacturer and/or country of 
origin. The most common names are:

7.92x57mm 
German military

7.92x57JS 
German military, European hunting ammo

7.90x57 
Portugal, Spain, Middle East, South America

8x57JS 
European hunting/sporting ammo

8mm Mauser 
Common commercial designation

8x57mm Mauser 
Common commercial designation

There is also 8x57J, which is a low pressure loading with slightly smaller bullet diameter that will work 
fine in 8x57JS rifles, but the accuracy isn't that great because the slightly smaller bullet doesn't fully 
engage the rifling in the JS diameter barrels.
There is also 8x57R (or 8x57JR, or 8x57JSR), which is a *rimmed* cartridge for use in German single-
shots and drillings. These should *not* be used in rifles designed for rimless cases (like the Mausers).
