Starline 223 Rem Unprimed Brass Cases - 100 Count Reloading

The Starline Brass 223REMEUP100 delivers precision-manufactured unprimed cases engineered for consistent reloading performance. These 223 Remington brass cases feature uniform wall thickness and precise dimensional tolerances that ensure reliable feeding and extraction across multiple reloading cycles.

What Makes This Different

Starline brass cases undergo a multi-stage manufacturing process that produces harder, more durable brass compared to standard military surplus cases. The controlled annealing process creates optimal neck tension while maintaining case head strength for extended case life. Each case features consistent flash hole diameter and primer pocket depth, eliminating the prep work required with once-fired military brass.

Key Features

• New unprimed 223 Remington brass cases ready for loading
• Uniform wall thickness within 0.0015" for consistent bullet seating
• Precise flash hole diameter of 0.080" for reliable ignition
• Standardized primer pocket depth eliminates pocket uniforming
• Heat-treated brass composition for 8-12 reloading cycles
• Compatible with all standard 223 Rem/5.56 NATO chamber specifications
• 100 cases per bag with consistent weight sorting

These cases excel in precision rifle applications where ammunition consistency directly impacts accuracy. The uniform case capacity reduces velocity variations between rounds, while the precise neck dimensions ensure consistent bullet release. Competition shooters benefit from the reduced preparation time, as these cases require minimal processing compared to military surplus brass. The harder brass composition maintains primer pocket integrity longer than softer commercial alternatives.
