    Hey D_Max! I have two German guns that use this round, what would you ask to ship them to NC? Thanks! Kevin.

    Guess I've just never seen the JR designation before.

    To be fair there are 2 projectile types for the 8mm round. The old version and the new version.

    Aren't the projectile diameters different for JR and JS? I could be wrong but its something to possibly be aware of

    Yes, the original 7.92x57 (8mm Mauser) was designated J or JR, and is .318 . It was originally a round nose bullet. The "modernized" cartridge used a spitzer bullet, is designated JS, and is .323 .
    I would not want to shoot the larger .323 in a smaller .318 bore. And shooting a .318 bullet in a .323 bore would be ok, but likely inaccurate.

    Interesting historical factoid.

    For years the round was called the 8 X 57 "J"S - actually still is. So what does the "J" stand for? All sorts of theories.

    Relatively recent research indicates that the German designation was the 8 X 57 "I" S - but when the name was converted to English, it became "J" because the German capital "I" looks like an English "J" - and at the time, due to the "Great War" no one really cared about the details. (This info is in Wikipedia, but I already knew it, so no cribbing Wiki).

    The "I" "S" is "infantry" "Spitzer", "spitzer" is a shortened form of the German word for "pointed." Even though incorrect, the "J" usage has carried on for over 100 years.

    Isn't the JR also a rimed cartridge?
