Winchester .357 Magnum Unprimed Brass Cases
Winchester unprimed brass cases are engineered to exacting tolerances, ensuring reliable feeding and positive chambering in your firearm. These cases are ideal for reloaders who demand quality components.
Manufacturing Excellence
During production, Winchester cases undergo annealing to achieve the correct hardness. This process creates brass that securely holds bullets while maintaining the flexibility needed for reliable firing. You may notice a light stain near the neck—this is a natural result of the annealing process and does not affect performance.
What to Expect
- Quantity: 100 unprimed cases per pack

Reloading Preparation
Before loading, you'll need to resize the case mouth and perform standard case preparation. An expander ball can be pushed through the neck in line with your sizing die if desired. This straightforward preparation ensures your brass performs consistently across multiple reloading cycles.
Trusted by hunters and competitive shooters, Winchester brass delivers the reliability you need for precision handloading.
