You'll have to make do with an existing top punch meant for some other bullet, hopefully you can match it up closely, the lesson here is to buy molds that you can get matching top punches. Most good quality mold/makers offer a top punch, some are cut with the same cherry used to cut the mold. You can fashion your own perfect fitting punch by using a large one and fill with 5 min. epoxy, just before it hardens, size a bullet, if done right, the bullet nose will form a perfect impression. Let epoxy completely harden and viola!!
