    I recently acquired a Lyman "No. 45" combined Bullet Sizer and Lubricator Press.


    These use Sizing Dies, and their complimentary plungers/punches, referred to as "G" (Top Punch)..."H" (Die Body)...and, "I" (Plunger which slides inside of the Die and, which also forces up the Sized Bullet for removal ) which Dies proper, have a three-decimal-place numeral describing their internal diameter...so, all is well there.


    The 'Top Punch' or "G" has it's own enumeration, which I gather, co-responds to the numerals originally assigned as suffixes to Ideal, and, later, Lyman Bullet Molds, for whose particular Bullet shape, the numerically co-responding Top Punch is intended.


    So, if I understand this right, interpreting the Top Punch Number, or, finding the number of a Top Punch one is after, would be greatly aided by having access to a comprehensive listing, with illustrations of the Bullet's shapes, of all Lyman (nee: Ideal ) Bullet Molds, from their beginning, in order to tell what any given Top Punch would be suited to.


    Yes?

    If you don't find the top punch you want there is a a good workable fix. Place the bullet in question coated with oil in the sizing die and add some epoxy to top punch and press it down and smooth the epoxy out. Once it's dried remove the bullet and sand/file the epoxy and ya got a custom top punch. I heard some do the with hot glue as well.

    The better your top punch fits the bullet, the less chance of deforming/damaging the bullet when sizing/lubeing.

    Thanks lordgroom,


    Nice...that List is 'priceless'!


    Too...would not be too hard to make to suit, on a Metal Lathe, if one needed to.
