Starline Brass 45 Winchester Magnum Unprimed Brass Cases 50 Per Bag

Starline Brass is well known among handgun reloaders for producing high-quality American-made unprimed brass cases, and the 45MAGEUP50 continues that tradition for the .45 Winchester Magnum cartridge. The .45 Winchester Magnum is a heavy-duty, lengthened version of the .45 ACP, and Starline's large magnum cases give reloaders the tough, uniform brass they need to push the round to its full potential in a suitable pistol platform.

These cases are drawn from solid brass in large magnum dimensions, with a trim length range of 1.191" to 1.196" that ensures consistent case dimensions across the bag. Each bag contains 50 unprimed cases ready for the reloading bench - no primers are installed, so you can select the primer type and load data that best suit your firearm and intended use.

Starline brass is sorted, inspected, and packaged for handloaders who demand reliable case dimensions for repeatable reloads. Whether you are loading for hunting, silhouette work, or simply stocking components for a future session at the range, these unprimed .45 Win Mag cases offer a solid foundation for quality handloaded ammunition.
