Winchester WSR Primers 5.56mm NATO-Spec Military #41 Box of 1000 (10 Trays of 100) Description
Winchester NATO-Spec Military Primers ( Winchester WSR Primers ) are the same primers that are used in the Lake City 5.56mm ammo, and they are manufactured by Winchester. Winchester WSR Primers are manufactured to strict standards to ensure consistent performance from shot to shot.
To ensure consistency and sensitivity, all primers are regularly and extensively tested at temperatures and under circumstances that are considerably beyond those seen in everyday use. When it comes to primer combination weights, Winchester ensures uniformity in size and quality, exact measurements and tolerances for anvil heights, and stability in the face of fluctuations in temperature and relative humidity even for the Winchester WSR Primers.
Winchester WSR Primers are #41 Small Rifle Primers, which are similar to the CCI No. 41 primers and are utilized by the military and original equipment manufacturers of small guns. No matter what the weather conditions are, these non-corrosive all-weather primers provide rapid and consistent ignition in every situation.
Under order to ensure consistency and sensitivity, primers are continually and carefully tested in temperature and environmental conditions that are much beyond those encountered in typical use. Enhanced sensitivity for more positive firing in all guns, carefully regulated weights of primer mixes, consistency in size and quality, exact measurements with tight tolerances for anvil heights, and stability in extremes of temperature and humidity are all guaranteed by Winchester.
Winchester No. 41 primer ( Winchester WSR Primers ) is more sensitive, easier to seat, and more compatible with progressive and automated loading equipment than even before. Winchester primers have always incorporated modern non-corrosive and non-mercuric initiator mixes.
Military-style semi-auto rifles seldom have firing pin retraction springs. If care is not used in assembling ammunition, a “slam-fire” can occur before the bolt locks. The military arsenals accomplish this using different techniques and components—including different primer sensitivity specifications—from their commercial counterparts.
Winchester makes rifle primers ( Winchester WSR Primers ) for commercial sale that matches military sensitivity specs that reduce the chance of a slam-fire when other factors go out of control*. If you’re reloading for a military semi-auto, look to Winchester Military primers
