Starline Brass 450 Bushmaster Unprimed Cases - 50 Count Bag

The Starline Brass 450 Bushmaster unprimed cases deliver the precision and consistency demanded by serious reloaders working with this powerful straight-wall cartridge. These brass cases provide the foundation for developing accurate hunting loads and match-grade ammunition for the 450 Bushmaster platform.

What Makes This Different

Starline manufactures these cases using proprietary brass alloy formulations that resist case head separation and maintain dimensional stability through multiple reloading cycles. The brass undergoes controlled annealing processes that optimize neck tension and case life compared to converted military surplus brass. Each case features uniform wall thickness and precise flash hole diameter for consistent ignition characteristics.

Key Features

• Premium brass construction with controlled grain structure for extended case life
• Precise headspace dimensions ensure proper chambering in all 450 Bushmaster rifles
• Uniform flash hole diameter of .080 inches for consistent primer ignition
• Annealed case necks provide optimal bullet seating tension
• Large rifle primer pocket sized to .210 inches diameter
• 50 cases per bag for convenient reloading batch sizes
• Compatible with standard reloading dies and equipment

These cases excel in hunting applications where the 450 Bushmaster's straight-wall design meets state hunting regulations while delivering substantial knockdown power on medium to large game. The consistent brass composition supports accurate load development for both subsonic and standard velocity applications. Reloaders report achieving sub-MOA accuracy with properly developed loads using these cases.
