    You figure it out

    I'm new and need help please. I mixed this up and thought I had it figured out and I'm just plain lost...I think.
    I mixed 5.5 lb ww + 8lb lead + 4 oz tin.= 7.4 bhn on lee tester. Ranch dog tlc460425rf boolit. I wanted somewhere around 12bhn so I mixed another batch to try.
    batch no.two
    I took 2lbs of the above alloy and added 24 oz ww. Quinched boolits com out @ 10.4 bhn.
    Can someone tell me what % pb / sb / sn is in this alloy?I' guessing at 94-4-4. Is this anywhere close? To what extent are these going to age harden or soften.
    Thanks

    Lastborn,
    No, your numbers are not close. There is likely no more than 2%Sb and just a fraction of a percent of Sn in your second 'test' alloy.

    Plain old clip-on ww's, with maybe a percent or two of Sn, will get you exactly where you want to be. Test some air-cooled bullets before going to quenched bullets. I load a lot of full-power heavy 44Mag bullets cast from straight air-cooled ww's, and they shoot great and leave the bore shiny. Correct sizing is much more important than exact alloy. Good luck.

    Alloy #1 = 96.8/1.2/2 Pb/Sb/Sn
    Alloy #2 = 96.7/2/1.3 Pb/Sb/Sn


    Modern WW alloy is ~ 96.5/3/0.5

    thanks JR

    Thank you JR. Could you tell me the simple way to calculate that please?

    Convert everything to ounces and go from there...

    Doing the math shows that Jr81452's numbers are spot-on, and I also concur on the modern ww formula. Good job.

    Just convert to ounces, calculate the quantity of the alloy components in ounces based on percentages, and then calculate the component percentages based on the combined weight of all components. I hope that makes sense.

    Allowing for 0.5%Sn in the 88ozs of ww's, that's 0.44ozs of Sn (.005 x 88= .44).
    Add to that the 4ozs of Sn, and that makes 4.44ozs Sn (4 + 0.44= 4.44).
    The combined weight in alloy #1 is 220ozs (88ozs+128ozs+4ozs=220ozs).
    4.44/220= 0.0201818 That's 2.01% Sn in alloy #1 (0.0201 x 100= 2.01).

    That's how you calculate the Sn weight and percentage in alloy #1. Use the same process to determine the other component weights and then percentages for alloy #1, and then simply repeat it with the relevant numbers for alloy #2 (32ozs of Pb96.8/Sb1.2/Sn2.0 and 24ozs of Pb96.5/Sb3.0/Sn0.5).

    Hope this helps, good luck.

    Ok I think I got it

    I think my problem was I didn't convert everything to ounces.
    I love this forum. The experience and knowledge here is great and ya'll don't mind sharing. I know I'll have more questions.
    Thanks

    Use the calculator I sent you via email

    If you must do it manually, convert everything to grains at 7000gr/1Lb

    There is no need to convert to grains, and multiplication of each pound by 7000 belabors the math enormously. There is no mathematical benefit to be had by conversion to grains.

    Simply convert all weights to ounces, and you're set. Most folks in the US measure bulk lead and tin in ounces anyway, so conversion to another weight standard is an unnecessary additional step, and potential source of error.

    Good luck.

    Forgive me sagacious, I have OCD. Even 1 hundredth of an ounce is 4.375gr. Not nearly precise enough to satisfy me. When I measure out alloy metals into ounce coins I measure 437.5gr +/- .05gr. I'm just sick that way

    Jr, do they let you out of the home at night, or just during daylight hours?

    They only let me out at night, right after the air-raid sirens are sounded.

    Don't know why, but I convert to grains also. Just easier for me I guess.
