Mounting between the shell plate and lock ring, the wear plate distributes pressure out over more of the shell plate giving your press smoother indexing and less flex while swaging or priming. It finishes off its accomplishments by replacing the ejector tab. No more need to deal with flimsy parts bending back causing your machine to crash. This also allows you to run a fully threaded die all the way to the shell plate in the last station, something other aftermarket ejection tabs prevent.
Parts are made from 4140 and given a coat of KG Gunkote.
