Lube the alignment Pins. Lee 2 cavity 9mm mold. Lee Info >Bullet mold lubing- Aluminum molds require occasional lubrication. A technique that works well is to have a glob of hard, stick-type bullet lube (like Lee #90007, but any alox/beeswax lube will work) about the size of a .45 slug rolled into a football; when the mold gets hot, touch one end to the aligning grooves along the sides of the mold block, on the underside of the sprue plate, and on the steel pins along the bottom of the mold block. Use sparingly, as if any gets into the mold cavity it will cause wrinkled bullets. Lack of lubrication will cause the mold blocks to mis-align, or the sprue plate to gall the top surface of the mold. Be sure to remember to "smoke" the mold which helps the mold release the freshly molded bullet without having to use "persuasion". http://castboolits.gunloads.com/showthread.php?t=88304
