Winchester Small Rifle Primers 41

Winchester NATO-Spec Navy Primers forty one are the exact 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 winchester 41 primers frequently and rigorously tested for consistency and sensitivity at temperatures and situations significantly beyond the array of usual use. Winchester assures carefully-managed weights of primer mixtures, regularity in size and high quality, precise measurements and tolerances for anvil heights and balance in extremes of temperatures and humidity.
