Winchester Tiny Rifle Primers forty one

Winchester NATO-Spec Military Primers 41 are the same primers used in the Lake Town five.56mm ammunition. These primers are built to exacting technical specs for shot to shot regularity. All primers are continually and rigorously tested winchester 41 primers for consistency and sensitivity at temperatures and situations much over and above the selection of normal usage. Winchester assures carefully-managed weights of primer mixtures, consistency in size and high quality, specific measurements and tolerances for anvil heights and balance in extremes of temperatures and humidity.
