Starline Brass 400 Cor-Bon Unprimed Cases - 100 Count Bag

The Starline Brass 400 Cor-Bon unprimed cases deliver consistent performance for handloaders seeking precision in this specialized bottleneck cartridge. Starline's manufacturing process produces cases with uniform wall thickness and proper headspace dimensions for reliable feeding and extraction.

What Makes This Different

Starline brass cases feature harder alloy composition compared to imported alternatives, extending case life through multiple reload cycles. The 400 Cor-Bon's bottleneck design requires precise manufacturing tolerances to prevent case separation, and Starline's quality control ensures proper shoulder angle and neck tension. Each case undergoes dimensional inspection before packaging, eliminating the sorting process required with lower-grade brass.

Key Features

• Premium brass alloy construction for extended case life
• Uniform wall thickness maintains consistent powder capacity
• Proper headspace dimensions ensure reliable chambering
• Clean, bright finish requires minimal preparation
• Small rifle primer pockets sized to SAAMI specifications
• Consistent neck tension for uniform bullet seating
• 100-count packaging with protective storage bag

The 400 Cor-Bon cartridge transforms .45 ACP platforms into high-velocity performers, making quality brass essential for safe operation. These cases handle the cartridge's 35,000 PSI operating pressure while maintaining structural integrity through multiple firings. Competitive shooters appreciate the consistent velocities achieved with uniform case capacity, while hunters rely on the precision needed for clean shots at extended ranges.
