Winchester Ammo WSC4570GU Unprimed Cases45-70 Gov Rifle Brass 50 Per Bag

If you're handloading .45-70 Government ammunition, Winchester unprimed brass cases give you a reliable foundation for custom rifle rounds. The Winchester Ammo WSC4570GU delivers 50 unprimed cases per bag—quality brass that reloaders trust for lever-action rifles, single-shots, and other .45-70 platforms. Unprimed cases let you control every step of the reloading process, from primer selection through final inspection, so you can tailor ammunition to your rifle's performance and your shooting needs.

Winchester brass is manufactured to consistent specs, which matters when you're sizing, priming, and loading multiple rounds. Whether you're working up hunting loads for big game or precision loads for a match rifle, starting with quality unprimed cases reduces variables and helps you achieve repeatable results. A 50-case bag is a practical quantity for testing loads, developing accuracy, or building a modest stockpile without overcommitting to a single batch.

Reloading your own .45-70 ammo lets you fine-tune bullet weight, powder charge, and velocity to match your rifle and hunting situation—something factory ammunition rarely offers. Winchester brass cases can be reloaded multiple times when treated carefully, making them economical for shooters who are committed to handloading and willing to track and sort their brass between sessions.

Frequently Asked Questions

What caliber rifle does this brass fit?

.45-70 Government—a classic cartridge used in lever-action rifles, single-shots, and some modern bolt actions. Check your rifle's markings to confirm caliber before purchasing.

Do these cases come with primers?

No, these are unprimed cases. You'll supply your own primers during the reloading process, which gives you full control over primer selection and load development.

How many times can I reload these brass cases?

Winchester brass is designed for multiple reloads. The exact number depends on your load intensity, handling, and inspection practices. Always inspect cases for damage, cracks, or excess wear before reuse.

Is 50 cases enough for reloading?

50 cases is a good starter quantity for load development, testing, or small batches. Many reloaders cycle through brass multiple times, so one bag can support ongoing practice or hunting seasons with careful brass sorting and storage.
