Remington Ammunition X22604 Kleanbore Centerfire Primer

Primer cup dimensions are controlled to four decimal places. The priming mix is specially formulated for consistent ignition with a wide variety of powder types, and tested for reliability over a temperature range of -20 degrees fahrenheit to +150 degrees fahrenheit. Individual primer pellet weight is controlled to .01 grams. A unique tripod anvil design creates a larger "sweet spot" with maximum sensitivity - even with off center firing pin strikes.
