lead test

[686]

i have a analytical test report on some lead. it list the lead to be.

79.49% lead
3.77 % antimony
.04 % arsenic
16.7 % tin

how would this work for bullets? i know the tin is high. would you add something to make a better bullet and keeping it hard. this was mixer by a person that did shoot a lots of bulls eye matches and liked it for good pouring and hard bullets with air cooling.

Are you water quenching?

[686]

no, just air cool.

Making boolits for what (80 percent use, at least)? ... felix

I would cut it with about 4 parts WW for hard bullets or 4 parts pure lead for softer ones. That's a lot of tin and it is expensive to use too much.

what do you mean 80 % use ?

he made 45 acp bullets for match shooting up to 50 yrds. bulls eye shooting. i have not used any and know that is a lots of tin.

[felix]

For acp use, then add with 4 or 5 parts of WW, making 5 or 6 parts total. ... felix

that would be my guess as to what he started with was ww's and just added a bunch o' tin.
i would add more like 7 parts ww's if you need them harder waterdrop.

felix what type of bullet would this make as is? do you mean mix 4-5 lb ww with 1 lb. of this stuf ?

[KYCaster]

Well, according to my calculations...you can't get there starting out with WW. Looks to me like equal parts linotype, 50/50 and pure Pb.

I don't know what he had in mind, but I think most here will agree that's a terrible waste of Sn.

If you add 1 lb. of your alloy to 19 lbs. of WW you'll end up with about 1.3 Sn, 2.6 Sb and 96.1 Pb. Not exactly WW + 1% Sn, but it should cast well and be slightly harder than WW.

KYCaster are you saying what i have is the same as 50-50 ww-liontype ?

No, with WW and lino it would be impossible to end up with more than 4% Sn. It would take 1/3 Lino, 1/3 50/50 and 1/3 Pb to get what you have.

You don't say what you will be loading for. In any case, >I< like a little more Sn in my alloy, up to 3% (any more is wasteful), so cutting your alloy with WW makes sense - 19-1 will give a reasonable alloy, and anything down to 9-1 will be just fine. I would mix @ 9-1...

i will be shooting target loads under 1000 fps. 9mm--38spl--40--45acp. i do make my lead a little harder than some and air cool. i have people saying 3-1 up to 9-1 ww-to this new lead. i guess i will do sone testing.
i have a lee 175 gr mold that i know the size and weight with my normal lead. i have made some harder and can see the smaller and lighter of the bullet.
i will put some of this new lead in my 150 lb pot and start testing. test as is then add ww and test again. i will keep doing this until i get my normal mix. this will also give me some mixes of different dardness if i want to make more.
