Thread: Lyman 429 677 round ball single cavity mold info needed.

  1. #1

    Lyman 429 677 round ball single cavity mold info needed.

    I found a Lyman single cavity round ball mold with the numbers 429 and 677 stamped on the sides, at a estate sale. I can't seem to find these numbers on any charts. I'm sure the 429 is the caliber but can't find the 677 on any charts for 429. Does anyone have any info on this mold. Thanks, Mike

    677 is the series (number count) of the that set on molds. Might be the 677 mold produced that month ect.

    You can easily judge the character of others by how they treat those who they think can do nothing for them.

    The 677 is a block serial number to keep the matching blocks in a pair together. It will be stamped on both mould halves. The 429 will be on only one block and it will be the round ball diameter.
