The PPU 8x57mm JS Mauser feeds bolt-action milsurp rifles chambered for the .323-inch bore diameter standard adopted by Imperial Germany in 1905. This load pushes a 198-grain full metal jacket to 2425 feet per second from a 24-inch barrel, producing 2585 foot-pounds of muzzle energy and a flat enough trajectory for 200-yard zeroes on iron-sighted K98k, Yugo M48, and Turkish Mauser platforms. Each round uses PPU‘s boxer-primed brass case — reloadable, non-corrosive, and manufactured to SAAMI maximum average pressure of 51,114 psi. The full metal jacket profile delivers consistent feeding through military-spec two-column magazines and penetrates steel targets without fragmentation, making it the utility choice for high-volume training on rifles whose actions were designed a century ago.
Built for the Box
PPU sources brass from its own mill in Užice, Serbia, drawing the case walls in multiple stages before annealing and trimming to 2.240 inches. The 198-grain bullet uses a gilding-metal jacket over a lead core, swaged to .323-inch diameter and a G1 ballistic coefficient of 0.559. That BC holds velocity better than lighter spitzers past 300 yards, though this load’s primary mission is sub-200-yard plinking and function drills. Boxer primers seat flush, and PPU’s quality-control protocol rejects cases with primer-pocket dimensional variance beyond 0.002 inches — a tolerance that matters when you’re cycling 80-year-old extractors.

This ammunition ships as a DOT-regulated hazardous material — review our 8mm Mauser ammo shipping restrictions before ordering. The 1.28-pound box weight reflects PPU’s use of corrugated cardboard rather than plastic trays, reducing dimensional variance during bulk pallet storage.
Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Observe the four fundamental rules of firearm safety at all times — treat every firearm as if it is loaded, never point the muzzle at anything you are not willing to destroy, keep your finger off the trigger until your sights are on target and you have made the decision to fire, and be certain of your target and what lies beyond it.
- Verify that your rifle is chambered for 8x57mm JS Mauser (.323-inch bore) and not the earlier 8x57mm J (.318-inch bore) — firing this ammunition in a J-marked rifle can result in excessive pressure and barrel damage.
- This product contains lead, a chemical known to the State of California to cause cancer and birth defects or other reproductive harm — wash hands thoroughly after handling and avoid inhalation of firing residue in poorly ventilated indoor ranges.
