I have a Lyman 356637 hollow point mold. The two mold haves are not concentric and the mold pin is too long, giving each boolit a hair lip. I sent it into Lyman for repair - the cavities are still eccentric, but they did replace the HP pin. They also graciously cross-threaded my mold handle screws and galled the screw head so I can’t set the mold on a table without scratching the surface (damaged screw threads don’t go all the way in anymore). Quality defects in manufacturing are understandable, but to further damage the product in your “repair shop” and refuse to make things right is more than I can accept. I’ll never buy anything new from Lyman again.
