Winchester Little Rifle Primers 41

Winchester NATO-Spec Navy Primers forty one are precisely the same primers used in the Lake Metropolis five.56mm ammunition. These primers are built to exacting specs for shot to shot regularity. All primers are frequently and rigorously winchester 41 primers tested for consistency and sensitivity at temperatures and problems considerably beyond the choice of normal usage. Winchester guarantees very carefully-controlled weights of primer mixtures, consistency in measurement and excellent, specific measurements and tolerances for anvil heights and steadiness in extremes of temperatures and humidity.
