Starline Brass 45-70 Government Unprimed Cases - 50 Count Bag

The Starline Brass 4570EUP50 delivers consistent, high-quality brass cases engineered specifically for 45-70 Government cartridge reloading. These unprimed cases provide the foundation for precision handloads that meet exacting standards for both accuracy and reliability.

What Makes This Different

Starline Brass cases undergo a proprietary manufacturing process that produces uniform wall thickness and precise internal dimensions. Unlike mass-produced alternatives, each case receives individual quality control inspection to ensure consistent neck tension and proper headspace. The brass alloy composition provides optimal balance between malleability for forming and strength for multiple reloadings.

Key Features

• Premium brass construction rated for 8-12 reloading cycles with proper care
• Uniform wall thickness within ±0.001" for consistent powder capacity
• Precise flash hole diameter of 0.080" for reliable ignition
• Annealed case mouths prevent splitting during bullet seating
• Large rifle primer pocket sized to SAAMI specifications
• Factory-fresh condition eliminates need for initial sizing
• Compatible with all standard 45-70 Government loading dies

These cases perform consistently across hunting applications from black bear to elk, delivering the case capacity needed for both traditional black powder loads and modern smokeless powder charges. The brass composition handles the substantial pressures generated by 405-grain cast bullets and 500-grain hardcast projectiles without primer pocket loosening or case head separation.
