About 8 x 68 S

The 8 x 68 S cartridge was developed in Germany by the renowned ammunition manufacturer RWS in 1939, designed to offer a significant performance boost to European hunters and shooters without requiring a magnum-length action. Its development was driven by a need for a long-range cartridge with superior ballistics that could handle the rigors of big game hunting. The 8 x 68 S quickly established itself as a favorite among European hunters due to its impressive power and versatility.

This cartridge features a bullet diameter of 8.2 mm and a case length of 68 mm, which is notably longer than most standard cartridges. The case is rimless and features a slight bottleneck design, contributing to efficient powder burning and consistent chambering. Reloaders will appreciate the spacious case capacity this cartridge offers, enabling a wide array of powder selections and load customization. The maximum average pressure for the 8 x 68 S is set around 4,200 bar, allowing it to push bullets at high velocities.

Ballistically, the 8 x 68 S excels in delivering high energy and flat trajectories, making it suitable for long-range applications. Typical bullet weights for this caliber range from 160 to 200 grains, with velocities in the vicinity of 3,000 feet per second for a 180-grain bullet. This energy and velocity ensure dependable performance on large game such as deer, boar, and even elk, particularly useful in open terrains where longer shots are common.

For the reloader, the 8 x 68 S provides ample opportunities to explore various projectile and powder combinations, optimizing performance according to specific hunting or sporting needs. The capability to tailor loads results in a versatile setup, accommodating personal preferences regarding recoil, accuracy, and terminal performance. This adaptability not only adds value for hunters but also appeals to competitive shooters looking for a high-power option suitable for large game and long-distance targeting scenarios.
