Nosler 30 Nosler Premium Brass Cases Unprimed 25/Box 10221

The Nosler 10221 Premium Brass delivers exceptional consistency and durability for handloaders seeking maximum performance from their 30 Nosler cartridges. Manufactured to exacting tolerances, this unprimed brass provides the foundation for precision ammunition that matches factory loads in accuracy and reliability.

What Makes This Different

Nosler's proprietary brass manufacturing process creates cases with uniform wall thickness and optimal hardness throughout. Unlike standard brass that may vary in dimensions by several thousandths, Nosler Premium Brass maintains tolerances within 0.001 inches across critical measurements. The carefully controlled annealing process ensures consistent neck tension and extends case life beyond typical expectations.

Key Features

• Weight-sorted brass within 1.0 grain for consistent performance
• Uniform wall thickness eliminates runout and improves accuracy
• Proper hardness prevents case head separation during repeated loading
• Flash holes deburred and chamfered for consistent ignition
• Case mouths chamfered inside and outside for smooth bullet seating
• Premium cartridge brass alloy resists work hardening
• Headstamp clearly identifies caliber and manufacturer

This brass performs consistently across temperature extremes and maintains structural integrity through multiple loading cycles. Competition shooters report groups tightening by 15-20% compared to standard brass when combined with quality components. The uniform case capacity ensures predictable powder charges and velocities, critical for long-range precision work where small variations compound at distance.
