Starline 50 Beowulf Unprimed Brass Cases - 50 Count Bag

The Starline 50 Beowulf unprimed brass cases deliver the foundation for precision handloading in this powerful AR-15 platform cartridge. These cases provide consistent wall thickness and proper headspace dimensions essential for safe, accurate ammunition development in the .50 Beowulf caliber.

What Makes This Different

Starline produces these cases using virgin brass with controlled grain structure, ensuring uniform case capacity and consistent powder charges shot after shot. The manufacturing process creates harder brass than many competitors, extending case life through multiple reloading cycles. Each case undergoes dimensional inspection to maintain the tight tolerances required for reliable feeding and extraction in semi-automatic platforms.

Key Features

• Virgin brass construction with controlled grain structure for consistent performance
• Proper headspace dimensions ensure reliable chambering and extraction
• Uniform wall thickness maintains consistent internal capacity
• Annealed case mouths accept bullets without splitting or deformation
• Flash hole deburred and sized for consistent primer ignition
• Compatible with standard large rifle primers
• 50 cases per bag for efficient bulk loading sessions

These cases handle the substantial pressures generated by .50 Beowulf loads, from subsonic 300-grain projectiles to full-power 400-grain hunting rounds. The brass composition maintains structural integrity through repeated firing and resizing cycles. Hunters appreciate the reliable expansion characteristics when loaded with appropriate powders for large game applications, while tactical shooters benefit from the consistent velocities achieved through uniform case preparation.

Technical Specs

Starline's reputation for dimensional consistency makes these cases the preferred choice for serious handloaders developing precision .50 Beowulf ammunition. The controlled manufacturing process eliminates the variables that plague mixed headstamp brass, allowing load development to focus on powder charges and bullet selection rather than compensating for case variations.
