Product Description
Starline .357 Magnum brass is manufactured in the USA for reloaders seeking high-quality, consistent cartridge cases. Designed for the popular .357 Magnum cartridge, this new, unprimed brass is suitable for handloading ammunition used in compatible revolvers and lever-action firearms.
The .357 Magnum cartridge is based on a lengthened .38 Special case. Although the two cartridges share certain dimensional characteristics, .357 Magnum brass is longer and is intended for firearms chambered for .357 Magnum.
