The unprimed casings from Starline are an excellent choice for your next reloading project. Built in America under strict quality control, they're designed to be easier to reload and deliver better results in the field. They are constructed out of vertically drawn brass that minimizes variations in cartridge wall thickness, and their flash holes are guaranteed to be free of burrs so that you don't have to spend time cleaning the holes. Unprimed Brass is non-returnable. | Starline 270 Winchester Empty Unprimed Brass
