8 x 75 S Load Data

The 8 x 75 S cartridge is a notable member of the robust family of rimless centerfire rifle cartridges that emerged from Germany in the early 20th century. Developed around 1912, the 8x75 S was introduced as a sporting round meant to bridge the gap between older black powder cartridges and the newer, higher performance smokeless powder designs of the era. The “S” in its designation stands for "Spitzgeschoss," indicating it utilizes a .323-inch (8.2mm) diameter bullet. Designed in response to a trend toward increased power and flatter trajectories, the 8x75 S was largely crafted for use in rifles originally chambered for the 8x57 IS. During the inter-war period, numerous rifles—especially Mauser actions—were converted or produced in 8x75 S, given its enhanced case capacity and velocity potential compared to its predecessors. Its German roots and evolving regulatory environment around rifle calibers solidified its use primarily among European hunters and shooting enthusiasts, and it retains a dedicated following among collectors and reloaders today.

In terms of application, the 8x75 S was conceived primarily for sporting use, particularly favoring European game hunting. Thanks to its improved ballistic performance and versatility, the cartridge was embraced for a wide array of hunting scenarios, making it popular in both driven hunts for wild boar and longer-range shooting at deer or chamois. Its case design allows for higher pressure and increased powder charge, providing a significant step up in muzzle energy and flat-shooting capability over the standard 8x57 IS. Many sporterized military rifles and custom builds continue to use 8x75 S, reinforcing its reputation as a dependable and effective medium-bore option for hunters and shooting sports enthusiasts.

When it comes to target species, the 8x75 S excels as a medium-bore cartridge suitable for most European big game. It has proven especially effective against wild boar, red deer, roe deer, and chamois, where flat shooting and reliable terminal ballistics are valued for both open terrain and wooded forests. Thanks to its energetic performance, it can tackle even larger European game under suitable conditions and within ethical hunting distances. The balance between manageable recoil and strong stopping power ensures its continued popularity for those seeking a versatile cartridge capable of handling the continent’s principal game animals. Its adaptability further extends its application to African plains game in some instances, where shooters seek a European classic with proven effectiveness.

For ammunition reloaders, the 8x75 S offers considerable flexibility. Typical bullet weights for the 8x75 S range from 180 to 220 grains, with most loads favoring the heavier end for deep penetration and reliable expansion—ideal attributes for big-game hunting. The correct bore diameter is .323 inch, matching the “S-bore” designation, and this must be respected for safety and accuracy. The cartridge’s capacity allows reloaders to experiment with a variety of modern powders, optimizing for velocity and precision, while the longer case length compared to 8x57 IS demands careful attention to overall cartridge length and bullet seating depth. Brass can be formed from several parent cases, further enhancing its appeal to handloaders eager to keep this classic cartridge in the field. Consistently, the 8x75 S remains a favored choice among aficionados of European rifles, blending heritage, reliable performance, and reloading flexibility into a cartridge that stands the test of time.
