Winchester Ammo WSC357SIGU 357 Sig Unprimed Brass Cases 100/Bag

The Winchester Ammo WSC357SIGU is a bag of 100 unprimed brass cases ready for .357 Sig handgun reloading. Winchester manufactures these shellcases to precise tolerances, ensuring smooth-feeding and positive chambering when run through your reloading press and fed into a finished pistol round.

These large primer pistol brass cases are sized for the .357 Sig cartridge and are intended for handgun reloaders who want consistent, factory-quality brass. The unprimed format gives the reloader complete control over primer selection, powder charge, and bullet seating, making them a solid foundation for range, duty, or personal-defense handloads built on the .357 Sig platform.

Each bag contains 100 pieces of brass unprimed cases. These are not loaded ammunition and are intended for use by experienced reloaders with appropriate reloading equipment, components, and current load data.
