Winchester Ammo WSC9U Unprimed Cases9mm Luger Handgun Brass 100 Per Bag

If you're loading your own 9mm Luger ammunition, Winchester Unprimed Cases deliver the brass foundation serious reloaders depend on. These 9mm Luger handgun brass cases arrive unprimed in convenient 100-round bags, giving you the flexibility to pair them with your choice of primers and loads. Winchester's manufacturing process includes annealing to achieve the right balance of hardness and flex — hard enough to hold the bullet securely, flexible enough to handle firing pressures without failure.

As unprimed cases fresh from the factory, they're ready for your reloading bench. You'll notice some may have a light stain near the neck; that's a normal byproduct of the annealing process and doesn't affect performance. Because they're manufactured and shipped as loose components, mouth imperfections occasionally occur — but that's standard. Before loading, you'll resize the mouth, chamfer, and deburr as part of your normal prep routine. Many reloaders also run an expander ball through the neck in line with the sizing die for consistent neck diameter.

Winchester brass is a trusted choice for competitive shooters and handloaders who want consistent, reliable cases that can be reloaded multiple times. At 100 cases per bag, you've got enough volume to keep your press fed without excessive bulk.
