Winchester Tiny Rifle Primers 41

Winchester NATO-Spec Military Primers 41 are precisely the same primers used in the Lake Town five.56mm ammunition. These primers are created to exacting technical specs for shot to shot regularity. All primers are continually and rigorously examined winchester 41 primers for regularity and sensitivity at temperatures and conditions considerably beyond the selection of regular use. Winchester assures thoroughly-controlled weights of primer mixtures, consistency in size and high quality, specific measurements and tolerances for anvil heights and security in extremes of temperatures and humidity.
