Frequently Asked Questions

What is unprimed brass and can I use it right away?

Are Winchester unprimed cases suitable for precision reloading?

Yes. Winchester brass is manufactured to consistent specifications and is widely used by handloaders for target shooting, hunting, and vintage rifle ammunition development.

Will these fit my 25-20 Winchester rifle?

These cases are manufactured for the 25-20 Win cartridge. Confirm your rifle's chamber marking before loading. If you're unsure of your rifle's exact specification, consult a gunsmith or the rifle's documentation.

How many rounds can I load from a 50-case bag?

One case yields one finished round. A 50-case bag will produce 50 rounds once you've added primers, powder, and bullets according to your reloading data.
