These unprimed cases undergo Nosler's proprietary manufacturing process to achieve uniform wall thickness and precise dimensions. Quality brass forms the foundation of accurate ammunition, and these cases provide the reliability competitive shooters and hunters demand.

What Makes This Different

Nosler Premium Brass cases feature weight-sorted construction with consistent case capacity variations under 0.5 grains. The brass receives proper annealing to optimize neck tension and case life. Unlike standard commercial brass, these cases maintain dimensional stability through multiple reloading cycles while delivering single-digit extreme spread velocity consistency.

Key Features

• Weight-sorted brass cases with uniform capacity for consistent velocities
• Proper annealing process optimizes neck tension and extends case life
• Precise headspace dimensions ensure reliable chambering in all rifles
• Unprimed cases ready for custom load development

These cases excel in precision rifle applications where ammunition consistency directly impacts accuracy. Long-range hunters benefit from the uniform ballistic performance, while competitive shooters rely on the consistent velocities for predictable bullet flight. The brass withstands magnum pressures without premature case head separation or neck splits that plague inferior brass.
