flux for lead

[MosinRob 1]

Going to try to cast some lead bullets. Bought some soft lead. Now im researching that you need to flux the melted lead. Some use chemical flux but a lot say just use sawdust. Anyone have a good direction to point me in?

Soft lead is NOT a good thing to cast bullets from.

Antimony added to the lead makes a much better bullet material, though I can't tell you the proportions because IDK

sorry should have been more specific. Only being used for Blackpowder conicals and round balls

Little bit of candle or bees wax should do it......

You can add a roll of 95/5 solder IIRC to get your alloy correct. More info is available at http://castboolits.gunloads.com/

If I remember correctly, solder is mostly tin, and as other have said, antimony is also used frequently to make lead harder for cast boolits. Different recipes for different hardness needs for each type of boolit.

 

For ML shooting, pure soft lead is best.

Take the soft lead that you have. Heat to just below 700F (pure lead flows better with some additional heat since you have no tin to assist with flow.)

 

You can flux with Brownell's Marvelux, sawdust including California Flake Flux, used motor oil, beeswax, parafin wax or anything else that protects the surface of the metal from the air.

 

Flux is designed to keep the lead in molten state from oxiding.

 

Have fun.
