Starline .38-55 Winchester Unprimed Rifle Brass, 50 per bag

Starline .38-55 Winchester Unprimed Rifle Brass (brand part no. 3855EUP50) gives handloaders a clean slate to build ammunition around, with no primers or dents from a prior firing to work around. Starline’s .38-55 Winchester brass holds to the standard 2.080″ case length used by the original Winchester case, but with thinner case mouth walls (about .0072″ average thickness at the mouth). That thinner wall allows a wider variety of bullet diameters to be seated, which matters in tight-chamber, large-bore rifles.
