Nosler Unprimed Brass Features The Nosler Unprimed Brass is manufactured from the same quality materials and held to the same tight tolerances as Nosler s own loaded ammunition giving reloaders a trusted starting point for building .45-70 Government cartridges. Each case uses a large rifle primer pocket sized for standard large rifle primers and the brass is new factory production rather than once-fired or reclaimed material. Consistent case dimensions mean more uniform neck tension and more predictable ignition from one round to the next. This consistency is exactly what high-volume handloaders are chasing when they choose to do their own case prep rather than buying fully processed brass. This bulk brass ships unprepped meaning it has not been case mouth deburred chamfered or flash hole deburred and it is not weight sorted at the factory. That leaves those prep steps to the reloader who can tailor the case prep process to their own precision standards and equipment. The brass features a brass metal finish typical of new unfired cases and is packaged in a 50-count bag for manageable reloading sessions. For handloaders who want Nosler s raw material quality without paying for prep work they intend to do themselves this bulk brass is available for sale at GrabAGun.
