Starline 38-55 Winchester Unprimed Rifle Brass Cases - 50 Count

The Starline Brass 3855EUP50 delivers precision-manufactured unprimed cases specifically engineered for 38-55 Winchester cartridge reloading. These cases provide consistent wall thickness and optimal brass hardness for reliable chambering and extraction across multiple reloading cycles.

What Makes This Different

Starline manufactures these cases using proprietary brass alloy formulations that maintain structural integrity through 8-10 reloading cycles when properly sized. The cases feature uniform primer pocket depth and consistent case mouth thickness, eliminating the sorting required with military surplus brass. Each case undergoes dimensional inspection to ensure SAAMI specification compliance for chamber pressure safety.

Key Features

• Premium brass alloy construction rated for multiple reloading cycles
• Consistent case wall thickness within 0.001-inch tolerance
• Uniform primer pocket depth for reliable ignition
• SAAMI specification compliance for safe chamber pressures
• Clean, unprimed cases ready for custom load development
• Precise case mouth dimensions for consistent bullet seating

These cases excel in precision rifle applications where consistency drives accuracy potential. The 38-55 Winchester chambering suits single-shot rifles and lever-action platforms for hunting medium game at moderate ranges. Starline's manufacturing process eliminates the brass preparation time associated with fired cases, allowing reloaders to focus on powder charges and bullet selection for optimal performance.
