Got a Lee .45, 200 gr. SWC double cavity bullet mold from Midway. The forward driving band would not cast well from one cavity. I cleaned the molds with brake parts cleaner and tried smoking, Khrol oil, and Frankford Arsenal Mold Release. I re-cleaned the molds after each try. Same problem, same cavity. Used wheel weights and also tried reclaimed range lead.
I have 3 other molds of different calibers and have had no problems of this type.
I called Midway and explained the problem and they are sending me a new mold and they are not requiring me to send the old one back. I appreciate their great service.
