It looks to me like his mold already has the penta pin.
Lee used to sell a pan lube kit, with a small, shallow pan, approximately 6" in diameter, and perhaps 3/4" deep. I still use mine, and can stand up 30 or more .357 boolits in it for lubing. I use Lee alox, or Javelina alox, and a fired case to cut them out of the lube, cookie-cutter style. It's a simple process, but a little time consuming. I do this for my .35 Whelen, .45-70, .38 special, and 7.62X54. I'm not shooting hundreds of boolits at a time, so it works ok for me.
