Winchester Little Rifle Primers 41

Winchester NATO-Spec Military Primers 41 are exactly the same primers used in the Lake Town five.56mm ammunition. These primers are designed to exacting technical specs for shot to shot consistency. All primers are consistently winchester 41 primers and rigorously tested for regularity and sensitivity at temperatures and problems much past the selection of regular utilization. Winchester assures thoroughly-controlled weights of primer mixtures, consistency in dimensions and top quality, exact measurements and tolerances for anvil heights and steadiness in extremes of temperatures and humidity.
