Forums Forums Ammunition Reloading Need help with setting up a Dillon 550C: wondering if something is potentially out of spec pertaining the shell plate bolt or the center hole. (bolt won’t go further in/screw in, and no, the brass tip set screw is not installed) more details in the comments. Thanks in advance.
