The Hornady .450 Marlin Unprimed Rifle Cartridge Cases offer an exceptionally uniform and premium structural foundation for precision handloaders developing custom, heavy-hitting ammunition for modern lever-action and single-shot rifles. Manufactured in small, specialized lots under rigid quality control standards, this high-grade rifle brass ensures excellent case-to-case consistency in internal powder capacity, weight, and wall thickness. Every case features precision-measured tight wall concentricity to minimize bullet runout and guarantee an ideal chamber fit, facilitating a clean, identical projectile release upon ignition. To withstand the demanding, high-pressure thresholds required by this hard-hitting caliber, Hornady subjects this component brass to rigorous factory pressure calibration testing to promote completely uniform case expansion during firing. Packaged as a loose component box of 50 unprimed brass cases, this American-made product features a standard Large Rifle primer pocket profile to give big-game hunters total command over their ignition properties.
