Over the past few nights all of a sudden, the first stage where it punches out the old primer, my shells are getting destroyed. It is chewing off the ridge on the metal base and making it almost smooth. Any idea why? Thanks.
Check the shell lifter which is in the sizing collet... For some reason it is not dropping down enough and the shell is is being formed to a bullet like shape... Take the shell lifter out and clean ... some type of dry lubricate is best for it.
Check to make sure the shell lifter is free to move withing the collet AND there is no debris like a piece of shot stuck in the way or between the collet fingers. It also needs to sit properly in the fork underneath the base.
