Remington Premier STS Primers #209 Shotshell

Remington Premier STS Primers are a collection of individual parts that are put together within each Remington with incredibly precise tolerances. The priming mix is specially formulated for consistent ignition with a wide range of powder types, and the primer cup dimensions are controlled to.0001″. Primers are put through reliability tests between -20 and +150 degrees F. Even with off-center firing pin strikes, the distinctive tripod anvil design creates a larger strike area with maximum sensitivity.
