Thread: Mold numbers

  1. #1

    Mold numbers

    Up for almost 48 hours so forgive me if I sound like a moron. So Lyman and maybe rcbs have the last 3 of there mold numbers as the cherry numbers, I have no clue what the first 2-3 numbers mean or what the cherry number is. I understand there are charts some place but those posts elude me at the moment. Maybe a more competent person could put a nice pretty sticky togeather with all the good little info. Really want to get more molds for when Ive had the sleep to use them but Lee is all I know how to translate

    First 3 are diameter last three are cherry number.

    Cherry number is just what number mold design that is for a particular manufacturer. E.g. 429 244 casts a bullet that is .429 diameter and was the 244th mold design made by company (Ideal/Lyman in this case).

    This table has all the Lyman/Ideal moulds that I have ever tried to look up. It even has moulds that haven't been made for decades, and some sort of picture and average weight for each. http://www.three-peaks.net/bullet_molds.htm

    The designations for RCBS/Ohaus moulds is much like the Lee ones, 2-digit caliber, 2-3-digit weight, and an abbreviation for the boolit profile. Examples: 44 240 SWC (just what it looks like), 45 230 CM (230 grain .45 round nose flat point, I think CM stands for cowboy mould), 22 55 SP (55 grain .22 Spire point).

    Saeco/Redding and H&G numbers are more confusing than Lyman/Ideal. Just a single number of up to 3 digits, like the Lyman cherry number, and no hint to diameter.

    That shoild cover most of the non-custom moulds. I'm sure someone will fill in any I missed.

    So you could have a 429244 and a 356244?

    Generally no. The cherry designs for the older designs are dedicated to a caliber. There are a few exceptions where cherry numbers have been recycled, but the only cherry number I know of that covers a wide range of diameters was cherry #56 which was for their round ball molds, Ideal stopped marking their RB molds with the cherry number pretty early, but I don't know exactly when.

    The three peaks chart is good, but far from complete. I have a number of Lyman and Ideal molds that aren't on their chart, and have seen a bunch of others. Examples include (just in .313 diameter) 313445, 313492, 31357 and 313631.

    Download/print the three-peaks chart ...it has pictures of the boolits and descriptions....extremely helpful print out. Lyman will send a free catalog that has all the current moulds listed.
    Between the two you will have a good reference of Lyman moulds.
    Mould numbers are very confusing...sometimes there is no rhyme or reason to the system . Pictures of the boolits are worth 1000 words .

    Actually, No.308244 (designed for the .30 Luger) was the 244th design by Lyman/Ideal. The number 244 was recycled in 1953 at the request of Ray Thompson (designer of No.429244) because his new SWC design's intended weight was 244 grains. The two No.244 designs appeared together in Lyman/Ideal lists and handbooks from 1953 until 1957 (after which No.308244 was discontinued). While a number of Lyman/Ideal cherry numbers were re-used over the years, this is the only instance where two designs bearing the same cherry number were catalogued simultaneously.
