Starline Brass 3855EUP50 .38-55 Winchester Unprimed Rifle Brass, 50 Count

Starline Brass 3855EUP50 .38-55 Winchester unprimed rifle brass is designed for reloaders seeking dependable, reusable cases for their .38-55 Winchester rifles. Manufactured from brass and supplied unprimed, these cases provide a consistent foundation for assembling customized rifle ammunition. The standard-length case design is compatible with the Winchester case specification, making it a practical choice for established .38-55 Winchester reloading workflows.
The case mouth features thinner walls than traditional Winchester cases, averaging approximately .0072 inch at the mouth. This construction supports the use of a wide variety of bullet diameters and can be especially useful in tight-chamber and large-bore applications. Reloaders should always verify firearm chamber dimensions, bullet diameter, loading data, and overall cartridge specifications before assembling ammunition. Proper case preparation, inspection, resizing, priming, charging, and bullet seating procedures are essential for safe and consistent results.
Each bag contains 50 Starline Brass cases for the .38-55 Winchester rifle cartridge. The cases are intended for reloading use and are not loaded ammunition. Their large rifle primer configuration and brass construction make them suitable for reloaders who want to develop loads for hunting, target shooting, or general range use where the .38-55 Winchester is appropriate. Use current, reputable reloading manuals and follow all component and firearm manufacturer recommendations when working with this cartridge.
