Nosler 10225 Premium Brass Cases 308 Winchester Unprimed 50/Box

The Nosler 10225 Premium Brass Cases deliver precision-manufactured brass components for 308 Winchester reloading applications. These unprimed cases provide the foundation for accurate, consistent handloads that exceed factory ammunition performance standards.

What Makes This Different

Nosler brass undergoes rigorous quality control processes that eliminate the dimensional variations common in standard cases. Each case receives precise neck turning and flash hole deburring operations. Wall thickness consistency stays within ±0.001 inches, compared to ±0.003 inches found in conventional brass. This manufacturing precision translates directly to improved accuracy and extended case life.

Key Features

• Premium brass construction with uniform wall thickness for consistent performance
• Precision flash holes deburred and sized to 0.080 inches for uniform ignition
• Annealed case necks provide proper tension and extended reloading life
• Weight-sorted within 1.5 grains for consistent internal capacity
• Chamfered case mouths ready for bullet seating without preparation
• Unprimed cases accept standard Large Rifle primers
• 50 cases per box with protective packaging to prevent damage

Range testing demonstrates these cases maintain primer pocket integrity through 8-10 reloading cycles with proper load data. The consistent internal volume produces velocity standard deviations under 15 fps with quality powder charges. Competition shooters report improved group sizes when switching from mixed headstamp brass to uniform Nosler cases. The brass accepts both match-grade and hunting bullet weights from 150 to 180 grains effectively.
