Starline 45 Colt Unprimed Brass Cases - 100 Count Bag

The Starline Brass 45LCEUP100 delivers consistent performance for handloaders seeking reliable 45 Colt brass cases. This 100-count bag provides premium unprimed cases engineered for multiple reloading cycles and precise chambering across various 45 Colt firearms.

What Makes This Different

Starline brass cases feature thicker case walls and optimized brass alloy composition compared to standard military surplus brass. The manufacturing process ensures uniform case capacity and consistent primer pocket dimensions. Each case undergoes quality control inspection to maintain tight tolerances for neck tension and overall length specifications.

Key Features

• Premium brass alloy construction rated for 8-10 reloading cycles
• Uniform case capacity within ±0.2 grains for consistent powder charges
• Precise primer pocket dimensions accommodate standard large pistol primers
• Factory-annealed case necks provide optimal bullet seating tension
• Compatible with all 45 Colt chambered revolvers and lever-action rifles
• Unprimed cases ready for custom load development
• 100 cases per bag for efficient bulk reloading sessions

These cases perform reliably across temperature ranges from -20°F to 140°F without case head separation or extraction issues. Competition shooters appreciate the consistent velocities achieved through uniform case capacity. The brass composition handles both light target loads and heavy hunting loads up to SAAMI maximum pressure specifications. Cases resize smoothly in standard reloading dies without excessive work hardening.

Technical Specs

• Caliber: 45 Colt (.452" bullet diameter)
• Case length: 1.285 inches
• Case capacity: Approximately 40.5 grains H2O
• Primer type: Large pistol primer required
• Material: Premium brass alloy composition
• Quantity: 100 unprimed cases per bag
• Manufacturing: Made in USA with quality control standards
• Compatibility: All SAAMI-spec 45 Colt chambers

Starline brass cases provide the foundation for accurate handloads that cycle reliably in single-action revolvers and lever guns. The consistent quality eliminates variables that affect accuracy and pressure curves. Serious handloaders choose Starline for load development work that demands repeatable results.
