Winchester WSC357MU unprimed brass cases deliver consistent performance for 357 Magnum handloaders seeking reliable, reloadable components. These factory-fresh cases feature Winchester's precise manufacturing standards and uniform wall thickness for optimal powder capacity and bullet seating.
What Makes This Different
Winchester brass cases undergo multiple quality control inspections during production, resulting in consistent case dimensions and weight tolerances within ±0.5 grains. The brass alloy composition provides excellent expansion and contraction properties during firing cycles. Each case features proper headstamp identification and maintains dimensional stability through multiple reloading cycles, typically lasting 8-12 reloads with proper sizing techniques.Key Features
