The Starline Brass 458 SOCOM unprimed cases deliver precision-manufactured brass components for serious handloaders working with this powerful cartridge. These cases provide the foundation for consistent ammunition performance in 458 SOCOM chambered firearms.
What Makes This Different
Starline Brass produces cases using premium brass alloy with precise dimensional tolerances that exceed industry standards. Each case undergoes multi-stage quality control testing to ensure uniform wall thickness and proper headspace dimensions. The manufacturing process creates cases with consistent internal capacity, resulting in more predictable powder charges and velocity consistency compared to mixed headstamp brass.
Key Features
- Premium brass construction with uniform wall thickness for consistent performance
- Precise headspace dimensions manufactured to SAAMI specifications
- Large rifle primer pocket sized for standard primers
- Unprimed cases ready for custom load development
- 50-count packaging for convenient quantity purchasing
- Compatible with all 458 SOCOM chambered firearms
- Reloadable multiple times with proper sizing and maintenance
These cases handle the substantial pressures generated by 458 SOCOM loads while maintaining structural integrity through multiple reload cycles. The brass composition provides optimal expansion and contraction characteristics during firing and resizing operations. Handloaders report consistent neck tension and reliable extraction when properly sized, making these cases suitable for both subsonic and supersonic load development.
