Greetings,
Yours are not necessarily junk.
Just check the critical dimensions prior to use.
I have not seen any finished Berdon plates and they may be case hardened.
Cheers,
Dave
Berdon shell plates are not hardened and they are pretty sloppy too. I have several of the machines as well as some parts. None of the shell plates I have encountered are hardened. I have a Berdon 9MM shell plate, but I wouldn't trust it to hold a 9MM case. The sizing die would probably pull the case right through the shell plate. I recently sold a Berdon 223 shell plate that worked better for 9MM than 223. I sold it as a stop gap until I have new 9MM shell plates.
