Starline 38-55 Long Unprimed Brass Cases x100

The 38-55 Winchester Center Fire (WCF) is a unique example among metallic cartridges — through almost 125 years of production, until quite recently, 38-55 cases had evidently never been made correctly for use with conventional bullets. Starline recently solved that problem. For most shooters loading conventional cast bullets in guns with standard 38-55 rifle bores and correctly cut chambers, using the 2.125-inch long, thin-necked, Starline 38-55 Winchester cases can provide a significant accuracy improvement.

#3855 - 38-55 Brass (2.080") (Large Rifle primer)

The .38-55 is the standard length of 2.080" which is the same as a Winchester case. Case mouth has thinnger walls (.0072" average thickness at mouth) than the Winchester case allowing for use of the wide variety of bullet diameters, especially in tight chamber/large bore situations.
