I have been looking at Lyman molds at gun shows and would like to know if anyone has a cheat sheet to cross reference the numbers so that you know for certain what caliber and weight it is you are looking at?

  The first 3 numbers of the 5 or 6 digit code identify the diameter(although it may not be exact),
  
  IE:
  
  358315 would drop a .358" diameter bullet.
  311299 .311"
  457195 .457"
  
  The last 2 or 3 numbers are generally just the order in which the design was produced.
  
  Castpics has most of the old Lyman/Ideal number info:

  Look under mould references on the left side of the page.

  I have an old Lyman reloader's handbook that lists and describes their cast bullets along with profile shadow pictures. This was the old spiral bound loose-leaf book prior to the book form that Lyman uses now. When I get to my reference library, I'll look up the number--maybe you can find one on fleabay.
  
  EDIT: I checked this AM. It's the 44th edition.
