Berger 4PH7217C .308 Winchester Unprimed Brass Cases - 100 Count

The Berger 4PH7217C unprimed brass cases deliver consistent wall thickness and precise dimensions for .308 Winchester reloading applications. Premium brass construction ensures reliable extraction and extended case life across multiple reloading cycles.

What Makes This Different

Berger brass cases feature uniform wall thickness within ±0.001 inch tolerance, significantly tighter than standard military surplus brass. The consistent internal capacity reduces velocity variations between rounds by up to 15 fps compared to mixed headstamp brass. Each case undergoes dimensional inspection to ensure proper chamber fit and reliable feeding.

Key Features

• Premium brass alloy construction for extended reloading life
• Uniform wall thickness within ±0.001 inch tolerance
• Consistent internal capacity for reduced velocity spread
• Large rifle primer pockets sized to SAAMI specifications
• Annealed necks for consistent bullet seating tension
• Flash holes deburred and uniform diameter
• 100 cases per box for complete lot consistency

Reloaders report 8-12 reloading cycles before case replacement when using moderate pressure loads. The consistent brass hardness eliminates the need for sorting by manufacturer, streamlining the reloading process. Match shooters benefit from the reduced extreme spread in muzzle velocity, typically achieving sub-MOA groups when combined with quality bullets and powder charges.
