Starline Brass 38-55 Winchester Unprimed Brass Cases 50 Per Bag

The Starline Brass 38-55 Winchester Unprimed Cases are premium American-made reloading brass from one of the most respected names in the reloading industry. These unprimed cases are produced to SAAMI specifications and engineered specifically for the classic 38-55 Winchester rifle cartridge, making them an excellent choice for handloading ammunition for vintage Winchester lever-actions, Marlin reproductions, and modern single-shot rifles chambered in 38-55 WCF.

Starline brass is manufactured in the USA from a signature 70% copper / 30% zinc brass alloy that is vertically drawn during production for uniform wall thickness. Each case runs at the standard 2.080" overall length (within a 2.076" to 2.082" tolerance) and features a .0072" average case-mouth wall thickness. A specialized heat-treat process enhances case strength and longevity, giving reloaders durable brass that holds up across multiple reload cycles.

This bag contains 50 unprimed brass cases ready for the reloading bench. As unprimed brass, these cases ship without primers, allowing the reloader to pair them with their preferred primer, powder charge, and bullet to assemble accurate, custom 38-55 Winchester handloads tailored to a specific rifle.

Starline has built its reputation on tight tolerances, consistent quality, and American craftsmanship. Whether you are a cowboy action shooter, a vintage rifle collector, or a hunter chasing meat with a classic lever-action, these 38-55 Winchester unprimed rifle brass cases deliver a dependable foundation for accurate, reloadable ammunition round after round.
