I recently started casting 356-125-2R (Lee Mold) 9mm. The mold is working great but my problem is the top punch I am using top punch number 311. I am casting with straight COWW and water quenching them. I will put the cast boolits in the 356 sizer die and run the lyman 4500 down but when the top punch comes in contact with the boolit, it leaves a ring around the top of the boolit, like it is marking the lead. Is this normal or is there a trick I don't know about.
