Winchester Ammo WSC45AU Unprimed Cases45 ACP Handgun Brass 100 Per Bag

Winchester Unprimed 45 ACP handgun brass cases give reloaders a reliable foundation for building consistent, accurate rounds. Whether you're loading for competition, duty practice, or general range work, these 45 ACP brass cases come in 100-count bags and are engineered to meet Winchester's quality standards. The cases are annealed during manufacturing to achieve the right hardness—tough enough to hold bullets securely, yet flexible enough to handle the firing cycle without premature failure.

Winchester's annealing process is designed to balance durability with performance, though you may notice a light stain near the neck on some cases—a normal byproduct of the heat-treating process. Incoming cases occasionally show minor imperfections in the mouth due to manufacturing or shipping, but these are easily corrected during your reloading prep work. Standard practice involves resizing the mouth, chamfering the case mouth, and deburring before loading; if you use an expander ball setup, it can be run in line with your sizing die to streamline the process.

These unprimed cases are a cost-effective way to reload 45 ACP when you already have your own primers, powder, and bullets. They're popular with handloaders who want to maintain tight quality control over their ammunition or who shoot enough volume to justify the time investment in brass prep and reloading.

Frequently Asked Questions

What preparation do these cases need before reloading?

These are unprimed cases, so you'll need to resize the mouth, chamfer and deburr the case mouth, and then prime them before powder and bullet loading. Some reloaders run an expander ball through the neck as part of the sizing process to further prepare the case.

Are primers included?

No—these are unprimed cases only. You'll supply your own primers, powder, and bullets as part of your reloading operation.

Why do some cases have a light stain near the neck?

The light stain is a normal result of Winchester's annealing process, which heat-treats the brass to achieve the correct hardness. It does not affect the usability of the case.

Can I use an expander ball with these cases?

Yes—an expander ball can be pushed through the neck in line with your sizing die as part of your reloading setup, though it's not required.
