Winchester Unprimed Brass Rifle Cartridge Cases in .220 Swift caliber deliver precision reloading components trusted by competitive shooters and precision rifle enthusiasts. This 100-count box provides high-quality unprimed brass cases engineered to exacting manufacturing tolerances, offering reloaders a reliable foundation for custom ammunition development. The .220 Swift cartridge—known for its exceptional velocity and flat trajectory—demands brass that maintains dimensional consistency through multiple reload cycles, and Winchester's annealing process ensures each case achieves the correct hardness balance.
During the manufacturing and annealing process, cases receive controlled heat treatment to produce the precise hardness needed to securely hold bullets while maintaining flexibility during firing. This thermal processing may result in light staining near the case neck—a normal byproduct that does not affect reloading performance. Cases may occasionally arrive with imperfect mouths due to the rigors of manufacturing or shipping; reloaders should plan to resize case mouths during their standard preparation sequence. Each unprimed case weighs approximately 2.4 lbs per 100-count box, providing substantial volume for long-range shooting programs or high-round-count practice sessions.
The .220 Swift remains a popular choice for varmint hunting, precision benchrest competition, and long-range target work where velocity and minimal bullet drop matter. Handloaders working with this caliber benefit from Winchester brass that maintains neck tension and headspace dimensions across multiple firings, reducing variability in ballistic performance. TacticalSurplusUSA supplies authentic Winchester component brass for reloaders committed to quality ammunition assembly and consistent downrange results.
These unprimed cases are sold as component brass only—no primers, powder, or bullets included. Reloaders should inspect each case and apply standard preparation techniques (cleaning, sizing, primer pocket uniforming) before use in their reloading press.
