Winchester .380 ACP Unprimed Brass Cases 100/Bag

Winchester Unprimed .380 ACP Brass Cases

Winchester unprimed brass cases are the foundation of quality handloads. These .380 ACP cases are engineered to exacting tolerances that ensure smooth feeding and positive chambering in your firearm.

Manufacturing Excellence

During production, each case undergoes annealing to achieve the correct hardness. This process creates cases that hold bullets securely while maintaining the flexibility needed during firing. You may notice a light stain near the neck—this is a natural result of the annealing process and does not affect performance.

What to Expect

• Quantity: 100 cases per bag
• Caliber: .380 ACP
• Condition: Unprimed, ready for your reloading process
• Quality: Manufactured to Winchester's exacting standards

Reloading Preparation

As unprimed cases, they require standard reloading preparation. The case mouth will need to be resized, chamfered, and deburred as part of your handloading process. Some reloaders prefer to run an expander ball through the neck in line with the sizing die for optimal results.

Occasionally cases may arrive with imperfect mouths due to manufacturing or shipping—this is normal and does not prevent successful reloading.

These cases are an excellent choice for handloaders seeking consistent, reliable brass for .380 ACP ammunition.
