Winchester Modest Rifle Primers forty one

Winchester NATO-Spec Army Primers 41 are the same primers used in the Lake Metropolis five.56mm ammunition. These primers are built to exacting specs for shot to shot consistency. All primers are regularly and rigorously analyzed for regularity and sensitivity at temperatures and circumstances much outside of the range of regular winchester 41 primers usage. Winchester guarantees meticulously-controlled weights of primer mixtures, consistency in measurement and excellent, exact measurements and tolerances for anvil heights and security in extremes of temperatures and humidity.
