Peterson Cartridge 9.5X77Mm Brass 50/Box

Peterson Cartridge 9.5x77mm brass is purpose-built for reloaders pursuing extreme long-range precision. This 50-round box of once-fired brass gives you the foundation for handloads capable of consistent performance beyond 2,200 yards. Derived from a necked-down 10.36x77mm design, the 9.5x77mm delivers the ballistic advantage serious ELR competitors demand—lower recoil impulse and faster target acquisition without sacrificing downrange capability. Whether you're developing match rounds for competition or pushing the envelope on your own, Peterson's annealed and cleaned brass ensures uniform case preparation and reliable chambering.

Peterson Cartridge has earned respect among precision reloaders for consistent quality control. Each case arrives fully annealed—the stress-relief process that keeps brass workable through multiple reloading cycles—and cleaned to remove manufacturing residue. That attention matters when you're chasing sub-minute-of-angle groups at distance. The 9.5x77mm has gained traction in the ELR community precisely because it offers shooters a flatter trajectory and gentler recoil curve than larger magnum rounds, letting you dial in your fundamentals and trust your brass to hold tolerances.

Your 50 pieces ship in a heavy-duty plastic ammo box, designed for long-term storage and safe transport to the range or reloading bench. For reloaders building a supply of premium brass, Peterson's consistent dimensions and quality annealing mean less sorting and prep work—more time developing loads and testing performance.
