Berger 4PH6009C 243 Winchester Unprimed Rifle Brass Cases 100/Box

The Berger 4PH6009C unprimed brass cases deliver consistent performance for 243 Winchester handloaders seeking match-grade accuracy. These precision-manufactured cases provide the foundation for developing custom loads that outperform factory ammunition in both hunting and competitive shooting applications.

What Makes This Different

Berger brass cases undergo rigorous quality control processes that ensure uniform wall thickness and case capacity within 0.5 grains. Each case features carefully controlled neck tension and flash hole consistency that surpasses typical commercial brass. The brass alloy composition balances durability with workability, allowing for multiple reloading cycles while maintaining dimensional stability.

Key Features

• Uniform case capacity within 0.5 grains for consistent powder charges
• Precision flash holes drilled to exact specifications for reliable ignition
• Controlled neck tension reduces bullet runout and improves accuracy
• High-quality brass alloy supports 8-10 reloading cycles with proper care
• Consistent case length eliminates trimming on first use
• Smooth case walls reduce extraction effort and chamber wear
• Match-grade tolerances support sub-MOA accuracy potential

These cases excel in precision rifle applications where consistency matters most. Competition shooters rely on the uniform performance for long-range matches, while hunters appreciate the accuracy improvements for ethical shot placement. The brass maintains structural integrity across temperature extremes and performs reliably in both bolt-action and semi-automatic platforms chambered in 243 Winchester.
