The Hornady powder cop die (Hornady #:  050063) is a simple powder check system that is easy to setup and use on any reloading press that accepts 7/8″ x 14 threaded dies. The die body acts as a carrier for the detection rod, and based on the load being checked, various heights can be used for placement of the white rubber O-Ring, which is used to indicate the powder level.
