Weatherby Select Plus 6.5 Wthby RPM Unprimed Brass Cases 50ct

The Weatherby Select Plus 6.5 Wthby RPM unprimed brass cases deliver the precision foundation needed for premium handloading in this high-velocity magnum cartridge. These factory-fresh cases provide the consistent wall thickness and dimensional uniformity that serious reloaders demand for maximum accuracy potential.

What Makes This Different

Weatherby's Select Plus brass undergoes stringent quality control processes that exceed standard commercial brass specifications. Each case features uniform wall thickness within ±0.001" tolerance and consistent case capacity that eliminates the sorting typically required with mixed-lot brass. The premium brass alloy composition provides optimal hardness for multiple reloading cycles while maintaining dimensional stability under the high pressures generated by the 6.5 Wthby RPM cartridge.

Key Features

• Premium brass alloy construction optimized for multiple reloading cycles
• Uniform wall thickness within ±0.001" for consistent performance
• Factory-fresh unprimed cases ready for custom load development
• Consistent case capacity eliminates need for volume sorting
• Weatherby headstamp for authentic cartridge identification
• 50-count packaging for efficient load development batches
• Compatible with standard large rifle primers

The 6.5 Wthby RPM cartridge generates velocities exceeding 3,400 fps with 127-grain bullets, placing significant stress on brass cases during firing and extraction. These Select Plus cases handle the cartridge's operating pressures of 65,000 PSI while maintaining proper headspace dimensions through multiple firing cycles. Handloaders report consistent accuracy results when developing loads for long-range precision shooting and hunting applications where the cartridge's flat trajectory provides advantages beyond 400 yards.
