Berger 4PH7080C 300 WSM Unprimed Brass Cases - 100 Count Box

The Berger 4PH7080C unprimed brass cases deliver consistent case capacity and wall thickness for precision 300 WSM handloading. These cases feature uniform construction that eliminates the variables affecting accuracy in factory ammunition.

What Makes This Different

Berger brass cases undergo rigorous quality control testing to ensure consistent case weight within 1 grain across the entire lot. The manufacturing process maintains uniform wall thickness from base to mouth, eliminating the weight sorting step required with many other brass manufacturers. Each case receives multiple annealing cycles during production to achieve optimal hardness for reliable primer seating and consistent neck tension.

Key Features

• Consistent case capacity within 0.2 grains for uniform powder charges
• Uniform wall thickness eliminates runout and improves concentricity
• Optimized hardness for reliable primer seating and extraction
• Flash hole deburred and chamfered for consistent ignition
• Case mouths chamfered inside and outside for smooth bullet seating
• Weight-sorted to within 1 grain tolerance across the lot
• Compatible with standard 300 WSM chamber specifications

These cases perform consistently across multiple reloading cycles when properly maintained. The uniform construction reduces velocity standard deviation in precision rifle applications, while the optimized brass alloy maintains case life through repeated firing and resizing. Competition shooters rely on this consistency for long-range accuracy, and hunters appreciate the reliability in field conditions.
