Winchester WSC3220U unprimed brass cases deliver the precision foundation serious handloaders demand for their 32-20 Winchester cartridges. These factory-fresh cases provide consistent wall thickness and proper headspace dimensions for reliable performance in lever-action rifles and single-action revolvers.
What Makes This Different
Winchester manufactures these cases using their proprietary brass alloy that maintains optimal hardness throughout multiple reloading cycles. The uniform case wall thickness varies less than 0.002 inches, significantly tighter than many competitors' tolerances. Each case undergoes dimensional inspection to ensure proper chamber fit in both rifle and revolver applications.
Key Features
- Factory-fresh unprimed brass ready for custom load development
- Consistent 0.408-inch rim diameter for reliable extraction
- Uniform wall thickness within 0.002-inch tolerance
- Compatible with both rifle and revolver 32-20 Winchester chambers
- Annealed case mouths prevent splitting during bullet seating
- Boxer primer pockets sized for standard large rifle primers
- 50-count packaging reduces per-case cost for volume reloaders
These cases perform consistently across temperature ranges from -20°F to 120°F without dimensional changes that affect accuracy. Competitive shooters appreciate the uniform internal capacity that produces consistent velocities shot-to-shot. The brass composition allows 8-12 reloading cycles with proper case preparation, making them cost-effective for high-volume shooting disciplines.
