    Ideal Alloy Recommendation

    Does anyone know what alloys IDEAL suggested before Lyman bought them out?

    Don't know exact answer, but if it exists (as an "official" IDEAL designation) it's probably derivable from a close look here:
    http://www.lasc.us/Fryxell_Book_textonly2.pdf

    Remember though, "IDEAL" went away as a company near 100 years ago. Thereafter it was Lyman.

    INCIDENTALLY: Can anyone tell me where the vaunted "Keith" 16-1 lead/tin alloy came to be known to have BHN of 12?
    My own testing says not much more than '8'

    Ideal Handbook #27, reprinted by Lyman just after they bought out Ideal and before they started doing their own revisions, states that 40:1 lead:tin is good enough for the average boolit, with 16:1 taking care of all hardness requirements except for .25 and .30 calibers with fast twists, where the judgement, backed by experimental data, of the caster/shooter must be employed for best results.

    There was no "Ideal Alloy" as such; not like Lyman #1 and #2.

    I only employ 3 alloys: Pure lead, 30-1 (effectively pure lead), and #2
    I've never found any reason (or any application) requiring anything else.
