Berger 4PH6060C 6mm GT Unprimed Rifle Brass Cases 100/Box

The Berger Bullets 4PH6060C delivers precision-manufactured 6mm GT unprimed rifle brass designed for competitive shooters and handloaders demanding consistent performance. Each case undergoes strict quality control to ensure uniform wall thickness and optimal powder capacity for the 6mm GT cartridge.

What Makes This Different

Berger's manufacturing process creates cases with tighter dimensional tolerances than standard brass offerings. The 6mm GT cartridge design provides superior ballistic efficiency compared to traditional 6mm cartridges, delivering flatter trajectories and reduced wind drift. Wall thickness consistency measures within ±0.0005 inches, contributing to shot-to-shot velocity uniformity that competitive shooters require.

Key Features

• Precision-drawn 6mm GT brass optimized for long-range accuracy
• Uniform wall thickness for consistent powder capacity and pressure
• Annealed case necks for proper bullet seating tension
• Flash hole deburring completed during manufacturing
• Compatible with standard large rifle primers
• 100 cases per box for efficient reloading sessions
