Premium unprimed .357 Magnum brass cases with uniform wall thickness, weight, and internal capacity. Pressure-tested for consistent case expansion and reliable reloading performance.
Hornady unprimed .357 Magnum brass cases provide the foundation for accurate, consistent handloads. Whether you're a benchrest competitor or a dedicated reloader, these cases deliver the uniformity and quality that separates good ammunition from great ammunition.
Tight Wall Concentricity Proper concentricity ensures your bullets seat correctly in both the case and your firearm's chamber. This precision alignment promotes uniform bullet release during firing, resulting in optimal velocity and accuracy.
Uniform Case Wall Thickness Accuracy begins with consistency. Hornady manufactures to extremely tight tolerances, ensuring wall thickness remains virtually identical across every case. This consistency is essential for predictable pressure curves and velocity.
Consistent Weight and Internal Capacity Every case in this 200-pack is virtually identical to the next, regardless of production lot. This means your reloads will exhibit consistent pressures, velocities, and accuracy—every single time you fire.
Extended Case Life Hornady treats their brass as the foundation of an accurate cartridge, not a commodity. You'll get significantly more reloads per case than inferior alternatives.
Pressure-Tested Quality Each case is run through pressure calibration testing to ensure uniform case expansion during firing, giving you confidence in every reload.
