    I was recently offered #250 lbs of old plumbing lead(piping ,drains etc)I'd like to use it for making shot,but pure lead does not work well for shot making.
    how hard is plumbing lead compared to tire weights?

    Soft, You need to add antimony.

    I've read that truing to alloy lead with other metals...tin,antimony etc is
    difficult if not impossible

    Plumbing lead is dead soft, but, formulaes exist allowing you to mix with harder alloys and achieve a suitable result. Adding tin will give you the flowing characteristics you need, but, it will still be soft..

    Melt your soft lead and clean thoroughly, then add to wheel weight lead at a ratio of about 25 lbs per 100 lbs of ww lead.

    I have used this in the past, and it flowed through the machine well, and broke targets well, also.

    You can also use soft, or pure lead, to dilute some that might be contaminated with other materials that will not flow through the drippers. (tin, zink, etc) I've done this, too

    I use Super Hard Alloy (30%-Antimony,-70%-Lead). I recently made 100 lbs of Stick on wheel weights that are soft lead. I use a 1 pound Super Hard Alloy (30%-Antimony,-70%-Lead) to 10 lbs stick on wheel weights. Shot turns out well. 10Tenner

    Bvr Tail has it right. 75/25 wheel weights to soft lead. it will flow with no problem.

    10tenner, your percentage of antimony is way too high and is working against you. Good hard magnum shot will only have 6-8 percent antimony and anymore then that is hurting weight. Antimony is almost half the weight of lead which translates to less pellet energy. Check the weight of your shot drop using your 30% formula vs. magnum shot and you will see the difference.

    antimony= .242 lb. per cu. inch.

    lead= .410 lb. per cu. inch.

    Toolmaker,

    10Tenner's ratio is UNDER the 6% level...

    Take one pound of 30% antimony = 0.3 pounds antimony, alloyed into 11 pounds of total weight gives a 2.7% number for the antimony.

    Just saying...

    You are right!!

    I tried playing around with adding soft stick on wheel weights to clip on wheel weights. I could not add much and then slow drippers, larger shot, and not round shot. 10tenner
