Starline 500 S&W Magnum Unprimed Brass Cases - 50 Count Bag

The Starline Brass 500SWEUP50 delivers premium-grade unprimed cases engineered specifically for the powerful 500 Smith & Wesson Magnum cartridge. These cases provide handloaders with the foundation needed to build consistent, reliable ammunition for hunting, target shooting, and long-range applications. Starline's manufacturing process ensures uniform case dimensions and reliable primer pocket consistency across each 50-case bag.

What Makes This Different

Starline brass cases feature thicker case walls and reinforced web construction compared to standard handgun brass, essential for containing the extreme pressures generated by 500 S&W Magnum loads. The company's proprietary annealing process creates optimal case mouth tension while maintaining structural integrity throughout multiple reloading cycles. Quality control standards include dimensional inspection and hardness testing on every production lot.

Key Features

• Premium brass alloy construction rated for multiple reloading cycles
• Reinforced case head design handles maximum SAAMI pressure specifications
• Uniform case wall thickness ensures consistent bullet seating depth
• Flash hole diameter held to ±0.001" tolerance for ignition consistency
• Proper annealing prevents case mouth splitting during bullet seating
• Compatible with all standard large rifle primers
• Factory-fresh cases require no preparation before first loading

These cases perform reliably across temperature extremes and pressure variations typical of 500 S&W Magnum applications. Hunters appreciate the consistent case capacity that translates to predictable velocity and trajectory performance with heavy bullets. Competition shooters benefit from the uniform dimensions that contribute to shot-to-shot consistency at extended ranges. The robust construction withstands the substantial recoil forces generated by full-power loads without case head separation or primer pocket loosening.
