Winchester Ammo WSC220SU Unprimed Cases220 Swift Rifle Brass 100 Per Bag

If you reload rifle ammunition, Winchester unprimed .220 Swift brass cases give you the foundation for building match-grade or hunting loads tailored to your rifle and requirements. These cases arrive ready for the full reloading cycle—sizing, priming, powder charging, and bullet seating—without the cost or lead time of factory ammunition. Each bag contains 100 cases, enough for a solid reloading session or to build inventory for regular range time.

Winchester rifle brass is manufactured to exacting tolerances and goes through an annealing process that strikes the balance between hardness and flexibility. The annealing ensures cases hold bullets securely while remaining resilient under firing pressure, which translates to consistent velocities and longer case life across multiple reloads. You may notice light staining near the neck—that's a natural byproduct of the annealing process and doesn't affect performance.

Before loading, plan to resize the case mouth, chamfer, and deburr as part of your prep work. Some reloaders run an expander ball through the neck in line with the sizing die to achieve uniform neck diameter. Because these are unprimed cases, you'll add primers during the priming stage of your reloading sequence. A few cases may show minor mouth imperfections from manufacturing or transport; inspect and set aside any that don't meet your standards before loading.

Frequently Asked Questions

What's included in the bag—do I get primers?

This is a bag of 100 unprimed cases only. You'll supply your own primers during the priming stage of reloading.

Why do some cases have staining on the neck?

The light staining near the neck is a normal result of the annealing process, which heat-treats the brass to achieve the right balance of hardness and flexibility. It does not affect performance or reloadability.

Do I need to prep these cases before loading?

Yes. Before you load, resize the case mouth, chamfer, and deburr. Many reloaders also run an expander ball through the neck in line with the sizing die for uniform neck diameter.

Is .220 Swift brass suitable for both hunting and target shooting?

Yes, .220 Swift unprimed brass is used by hunters and competitive shooters alike to build loads for their specific applications and rifles.
