Historical Summary

Germany’s 7.92×57mm Mauser cartridge (often called “7.9mm”) served as the core rifle and machine-gun round of the Wehrmacht during WWII. While early service loads used lighter bullets, the s.S. (schweres Spitzgeschoss, “heavy spitzer”) load became a preferred long-range ball pattern for machine-gun use and general service, pairing a streamlined boat-tail FMJ projectile with strong down-range performance.

This example is a complete, original 15-round box labeled “Patronen s.S.”, packed in 1939 under manufacturer code P635 (Hirtenberg, Lower Austria). The year “39” appears both on the box label (Lot notation “L. 39”) and on the case headstamp.

The box label is especially useful because it records component sourcing in one place: case lot, bullet lot, primer type (Zdh. 88), and powder designation with maker and lot information.

Collector Notes

For K98k and MG34/MG42 companion displays, intact German cartons with legible labels and matching headstamps are often more desirable than loose rounds.

Corrosive primers: The Zdh. 88 primer type is corrosive. If any round is ever fired, clean the firearm promptly using a water-based method to flush primer salts, followed by normal cleaning and oiling.
