antimony ?

[gunslinger20]

Can antimony bought on ebay as a refined ingot be melted into a lead alloy to add antimony % to the cast boolits? I guess a better ? would be what is the melting point of antimony.

Get it at Rotometals and support one of our sponsors:

30% Antimony, in ingot form, and ready to alloy.

Highly recomended that you buy the 30% superhard instead of pure antimony.
Pure antimony is a royal PITA to deal with .
Besides that , the superhard comes with free lead in it already.

Monotype is also quite high in antimony, if you can find that. enjoy Mike

Rotometals "Super-Hard" is best since you know the exact composition and it is in a form that is easy to mix into any alloy !

"antimony ?"

I have some high antimony lead (19% anitmony, 2.5% tin and 78.5% lead - BHN 24) that I will sell you for $2.50 an pound. Checked with a metal gun at the local scrap dealer.
Let me know if I can be of help.

A fair and exceptable price.

Can a rookie ask, how much of this alloy to how much lead?

a good all around bullet recipe would be 4-6% antimony 2-3% tin and the rest lead or use clip on wheel weights and add 1% tin good for med to lighter magnum handgun loads or lower velocity rifles @ 1600 fps or slower

I'm going to try to lay this out for the non math whiz guys.
When trying to calculate percentages and how much of what , try to think in 100 pound batches. Then divide everything by the same amount like 1/4 or whatever.

First decide what you want.

Lets say that you want 2-6-92 tin-antimony-lead. That means that you want 6 pounds of antimony. One pound of 30% antimony has .3 pounds of antimony.
10 pounds of superhard would have 3 pounds of antimony and 20 pounds would have 6 pounds of antimony with a balance of 14 pounds of lead.

Figure the tin the same way. Say you have some 50/50 solder and you want 2 pounds of tin in the mix. 4 pounds of the 50/50 gives you that plus the 20 pounds of superhard now is 24 pounds in all.

You need to add 76 pounds of lead for a total of 100 pounds of 2-6-92.
A 100 pound batch is a lot for many folks so maybe a 25 pound batch is more reasonable.
Simply divide everything by 4. 5 pounds superhard, 1 pound 50/50 solder and 19 pounds of lead.

I really hope that this does not come across as condescending. I just wanted to show an example of how thinking in 100 Pound batches helps simplify things.

I am intrested. I sent a pm but dont know if it sent for sure so if I am repeating, sorry. How did you determin what the %s of the alloy was, I understand the BHN. How much do you want to get rid of?

Very good link Thanks
