Hornady Unprimed Rifle Cases .308 Winchester (MPN: 8661 / 8661BAG)
Match-grade handloaders, long-range competitors, and big-game hunters know that building ultra-consistent ammunition requires foundational brass engineered to exact dimensional standards. Hornady designed their .308 Winchester unprimed component cases specifically to solve the headaches of case-to-case internal capacity variance, uneven neck wall thickness, and sloppy primer pocket seating. Manufactured to tight tolerances, these premium unprimed cases give precision reloaders the structural uniformity needed to achieve single-digit standard deviations in muzzle velocity.
Produced in Grand Island, Nebraska, Hornady utilizes strict drawing and quality-control protocols to ensure superior case wall concentricity and grain structure. Each case is engineered with uniform wall thickness along the body, shoulder, and neck to allow smooth bullet seating and consistent neck tension pass after pass. Featuring precisely drilled flash holes and standard Large Rifle primer pockets, Hornady subjects these cases to target-line inspection standards, balancing durability at the case head with optimal flexibility at the shoulder for long reloading lifecycles.
At the loading press and downrange, expect seamless chambering and positive extraction across precision bolt-action rifles and gas-operated AR-10 platforms. These virgin component cases are factory-cleaned, deburred, and packaged ready for sizing, charging, and seating. Whether handloading heavy match projectiles for 1,000-yard target scoring or dialing in custom hunting loads for big game, this 50-count bag delivers American-made precision to your reloading bench.
Armorer Bench Notes & Technical Maintenance Guidance
Shipping Restrictions: Unprimed brass component cases are non-hazardous, non-regulated items and can ship via standard ground services. Always verify state and local laws prior to placing component orders.
Armorer Tip: Even though virgin Hornady brass is held to tight manufacturing tolerances, always run new cases through a full-length sizing or neck-sizing die prior to loading to correct any minor mouth out-of-roundness caused during transit. Chamfer and deburr the case mouths lightly to prevent jacket shaving during bullet seating. When reloading for semi-automatic platforms like the AR-10 or M1A, inspect headspace with a drop gauge to ensure reliable bolt battery lockup.
