Winchester Ammo WSC22250U Unprimed Cases22-250 Rem Rifle Brass 100 Per Bag

Winchester unprimed brass for .22-250 Rem delivers quality reloading components for hunters and competitive shooters who demand precision and consistency. These rifle cartridge cases arrive ready for the reloading process—sizing, priming, charging, and seating. Each box contains 100 cases, enough for a solid session at the bench or to stock your reloading inventory. Winchester's manufacturing process includes annealing to balance the hardness needed to hold a bullet securely with the flexibility required under firing stress, so you may notice a light surface stain near the neck on some cases—that's normal and doesn't affect performance.

Reloading with Winchester brass means starting with cases built to tight tolerances and consistent wall thickness. The .22-250 Rem is a versatile cartridge favored for varmint hunting and precision rifle work, and beginning with quality unprimed cases gives you full control over every step of the reload. You'll size and shape each case to your specifications, chamber and debur the mouth, prime, charge, and seat bullets to your exact standards.

Expect that some cases may arrive with imperfect mouths due to the demands of manufacturing and shipping—this is typical. Your reloading die setup will address these irregularities as part of the sizing and finishing process. If you choose to use an expander ball ahead of your sizing die, you can run it through the neck to prepare the case mouth. With Winchester's reputation for consistency and these cases' proven track record among serious reloaders, you're investing in components that will help you build ammunition you trust.

Frequently Asked Questions

Can I use these cases for varmint hunting reloads?

Yes. The .22-250 Rem is a proven varmint cartridge, and Winchester unprimed brass is widely used by hunters building custom loads for varmint work.

What reloading steps do I need to perform on unprimed cases?

You'll need to size and shape the case to your die specifications, resize and deburr the case mouth, prime the pocket, charge with powder, and seat the bullet. Your sizing die will handle case mouth irregularities that may occur in manufacturing or shipping.

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

Winchester's annealing process—which hardens the case to hold bullets securely while maintaining flexibility under firing—can leave a light surface stain on some cases near the neck. This is normal and does not affect performance.

Do I need to use an expander ball with these cases?

An expander ball is optional. Some reloaders choose to run one through the case neck ahead of sizing to help prepare the mouth, but it is not required for the reloading process.
