In the past I have only been casting boolits for my 45 but just purchased a mold for 9mm. I bought an RCBS 9mm-115-RN part number 82026. I cleaned the Oil off the mold with break cleaner before use and it drops bullets easily however I am getting flashing on the nose as seen in the attached pictures. When I hold the mold up to the light I can see a sliver of light in the nose of the cavity where I am getting the flashing. Since this is my first steel mold I have come here for advice on what to do. The gap doesn't seem to change if I really squeeze down on the handles. Any ideas?
Thanks
