    I have a mec 9000H that I just acquired. I'm having trouble with the deprime/resizing station, the shells want to hang up on the primer punch. Sometimes it knocks the brass off the hull or the next time it does it the shell doesn't want to release of the primer punch. I'm reloading green sts shells and I also switched out primer punches from my other 9000G and it still does the same thing. I also took apart the resizer and cleaned it and put never seize on the outer part of the collet. If anyone has any ideas why this is happening I would really appreciate it.

    thanks todd

    put a little grease on your finger and put it on the outside of the collet.
    thats all it will take

    I took apart the collet and cleaned it and put never seize on the outside of the collet. The shell is hanging up on the deprimer punch, that is what it is stuck on. The collet is free when this happened.

    The collet may be closing too soon. Review the adjustments on page 25 of the owners manual. If you don't have it, the URL is where you can find it.

    Would the collet closing to soon make the hull want to stick to the primer punch?

    There is a undercut machined inside the collet fingers, this recess is for the rim of the shell and without it the collet would size the rim along with the rest of the brass. It sounds like the collet is releasing too soon, before the punch has a chance to retract from shell. This undercut also holds the rim as the punch is rising.

    Figured out what was wrong with my loader. The collet was the wrong one, it was for some other loader that mec made and was for low brass shells. I bought this loader used and I guess somebody put in the wrong collet at some point in time. I pulled the collet out of my other 9000G and put it in and now it's working like it should.

    Thanks to everyone who was replying and offering suggestions.
