Winchester Magnum Rifle Primers
Winchester® non-corrosive, all weather primers deliver fast, dependable ignition under any shooting condition. Without a good primer, the only that happens when your firing pin falls is that trophy of a lifetime walks away. Winchester tests their primers rigorously for consistency and sensitivity at temperatures and conditions far beyond the range of normal usage. Winchester magnum rifle primers maintain stability in extremes of temperature and humidity in both loaded ammunition or stored in boxes on the shelf.
