Winchester Tiny Rifle Primers 41

Winchester NATO-Spec Navy Primers forty one are the exact same primers used in the Lake Metropolis 5.56mm ammunition. These primers are crafted to exacting specifications for shot to shot consistency. All primers are consistently and rigorously analyzed for regularity and sensitivity at temperatures and conditions much over and above the number of regular winchester 41 primers usage. Winchester guarantees very carefully-controlled weights of primer mixtures, regularity in dimensions and high-quality, specific measurements and tolerances for anvil heights and steadiness in extremes of temperatures and humidity.
