Winchester WSC220SU Unprimed 220 Swift Brass Cases - 100 Count

Winchester WSC220SU Unprimed Cases deliver premium brass construction for 220 Swift reloaders demanding consistent performance and extended case life. These factory-fresh cases provide the foundation for precision handloads that maximize the 220 Swift's exceptional velocity potential. Each case undergoes Winchester's quality control process to ensure uniform wall thickness and proper dimensions.

What Makes This Different

Winchester brass cases feature drawn construction from high-quality brass alloy that maintains structural integrity through multiple reloading cycles. The uniform case wall thickness promotes consistent powder burn and bullet seating depth compared to mixed headstamp brass. Factory annealing optimizes case neck tension while maintaining body strength for reliable extraction and feeding.

Key Features

• Premium brass construction rated for 8-12 reloading cycles with proper care
• Factory-fresh unprimed cases ready for custom load development
• Consistent case capacity within ±0.5 grains for uniform velocities
• Proper headspace dimensions ensure reliable chambering in 220 Swift rifles
• Annealed case necks provide optimal bullet grip and release
• 100-count packaging reduces per-case cost for volume reloaders
• Compatible with standard large rifle primers and 220 Swift load data

These cases excel in precision rifle applications where consistency drives accuracy. The 220 Swift cartridge's high-velocity characteristics demand quality brass that withstands chamber pressures exceeding 50,000 PSI. Winchester's manufacturing process produces cases with minimal weight variation, contributing to velocity spreads under 20 fps in properly developed loads. Varmint hunters and competitive shooters benefit from the repeatable performance these cases enable.
