Winchester Small Rifle Primers 41

Winchester NATO-Spec Armed forces Primers 41 are precisely the same primers used in the Lake Metropolis five.56mm ammunition. These primers are constructed to exacting requirements for shot to shot regularity. All primers are consistently winchester 41 primers and rigorously analyzed for regularity and sensitivity at temperatures and circumstances significantly beyond the choice of typical utilization. Winchester ensures carefully-controlled weights of primer mixtures, consistency in dimension and high-quality, specific measurements and tolerances for anvil heights and steadiness in extremes of temperatures and humidity.
