Description

The Winchester WSC30CU delivers consistent performance for handloaders seeking reliable 30 Carbine brass cases. These unprimed cases provide the foundation for precision ammunition development with Winchester's proven manufacturing standards.

What Makes This Different

Winchester brass cases undergo multi-stage quality control processes that ensure uniform wall thickness and proper headspace dimensions. The annealing process creates optimal neck tension for consistent bullet seating, while the flash hole deburring eliminates ignition inconsistencies common in budget alternatives. Each case meets SAAMI specifications for chamber pressure and dimensional tolerances.

Key Features

Unprimed 30 Carbine brass ready for custom load development
Uniform wall thickness within 0.001" tolerance for consistent performance
Properly annealed case necks prevent work hardening and splitting
Flash holes deburred and sized to 0.080" diameter for reliable ignition
SAAMI-spec headspace dimensions ensure proper chamber fit
100-count packaging provides sufficient quantity for load development
Reloadable multiple times with proper case preparation techniques

These cases perform consistently across various powder charges and bullet weights, from light 85-grain plinking loads to full-power 110-grain hunting ammunition. The brass composition maintains structural integrity through multiple firing cycles when properly sized and trimmed. Competition shooters and hunters alike benefit from the predictable pressure curves and velocity consistency that quality brass provides.
