The Winchester™ Large Rifle Primers deliver fast, dependable ignition under any shooting condition. The Winchester™ WLR Primers are constantly and rigorously tested for consistency and sensitivity at temperatures and conditions far beyond the range of normal usage.
Winchester™ feels so strongly about their primer performance that they guarantee better sensitivity and greater positive firing in all guns. Winchester uses carefully-controlled primer mixture weights, as well as precise measurements and tolerances, which result in greater stability in extreme temperature and humidity.
