KARABINER 98 KURTZ : 8MM! Yeah but, these rifles use "JS" or "JRS" ??

Discussion in 'General Firearms Forum' started by tucojuanramirez, Jul 13, 2012.

  1. good morning.
    I've been to some forums about mauser k98k.
    But I've no answers about this question.
    I'm going to buy a k98k and I've found in internet that some business listings say that the rifle use the 7.92x57 "JS" and some others the 7.92x57 "JRS".
    I've read the differences between these two kind of ammos...but...depends on what???

    thank you friends!

    7.92X57JS is also referred to as 8mm Mauser.

    The "JRS" I am not familiar with, but it could just be a typo.


    BTW....the K98K is probaly the best bolt action rifle ever produced!!!!

    Guns in military calibers are forbidden in much of Europe, Pacific Islands and Central/South America. Hence 8MM JS Mausers are often rechambered in 8MM JRS.

    Same reason why you have to buy a pistol in 9X21 in Italy instead of 9MM luger, and the 45 ACP Short instead of 45 ACP.

    HMM. I thought it was related to the change in bore diameter when they switched from the round nose to the spitzer bullet, but IIRC that was the "S" so the "R" for rimmed makes sense

    If you look at European ammo makers, they typically offer at least four variations of the 8MM mauser. The .318 J military cartridge & the .318 JR Rimmed sporting cartridge. The .323 JS military and the .323 JRS Rimmed sporting cartridge.

    About 10 years ago, a gaggle of the J, JS and JRS was imported into the USA from Sellier & Bellot and sold by J&G Sales (among others).

    Didn't the drillings and such guns use the rimmed rounds?

    can you please elaborate on the .45 short, a round Gaston copied and called the.45 GAP perhaps ?

    The .45 Short, I think the same as the .45 Jaeger, is a rule beater cartridge the same as .45 ACP except slightly shorter so that .45 ACP will not chamber in a barrel made for it. It is not the same as .45 GAP and predates it by a good many years.

    I was not aware that there was anything being done to convert 8x57 bolt actions to 8x57R. Little or nothing to do to the chamber but the bolt face and extractor would have to be widened and getting a Mauser magazine to handle rimmed cartridges can be a challenge.

    The small firearms industry in India devised the .315 Sporting Rifle for similar restrictions. It amounts to a .303 British necked up to 8mm and chambered in Lee Enfield type rifles. Strangely, you can also get a plain old American .30-06 too.

    The Germans, faced with the terms of the Versailles Treaty, went to an 8x60 chambering so they did not make more 8x57s than allowed for the small post WWI army.

    Alaska, again (for now)


    Yep, Drillings and Double rifles, often used Rimmed cartridges for better extraction.
     
  12. Even though it looks like 8x57 JS, it is 8x57 IS, the I standing for Infanterie.
