Winchester WSC38AS+U Unprimed Brass Cases 38 Super +P 100/Bag

The Winchester WSC38AS+U delivers premium unprimed brass cases engineered specifically for 38 Super +P handgun cartridges. These cases provide reloaders with consistent wall thickness and precise dimensions that ensure reliable chambering and extraction across multiple loading cycles.

What Makes This Different

Winchester brass cases undergo a multi-stage annealing process that creates uniform grain structure throughout the case body and neck. This controlled manufacturing results in brass that maintains structural integrity under the higher pressures of 38 Super +P loads, typically rated at 36,500 PSI maximum average pressure. The cases feature consistent flash hole diameter and primer pocket depth that eliminates the dimensional variations common in budget brass.

Key Features

• Premium brass alloy construction rated for multiple reloading cycles
• Precise case mouth diameter of .356 inches for consistent bullet seating
• Uniform case length of .898 inches with minimal length variation
• Large pistol primer pocket sized to .210 inches diameter
• Annealed case necks prevent splitting during bullet seating
• 100 cases per bag with protective packaging
• Compatible with all standard 38 Super +P chamber specifications

These brass cases perform consistently in competition environments where ammunition reliability directly impacts match results. The uniform case capacity ensures consistent powder charges translate to predictable velocities and accuracy. Law enforcement agencies appreciate the reliability factor when loading duty ammunition that must function flawlessly under stress. The cases maintain primer pocket tightness through multiple loading cycles, reducing the primer flow issues that plague softer brass alloys.
