Casting today

[Canuck44]

I recall reading several years a go that while water quenching does harden the bullets if you then run them through a sizing die the hardening is diminished. Since I only cast handgun bullets I 've never worried about water quenching. Wheelweights have several alloy minerals in them like tin, antimony & zinc which makes them plenty hard enough for pistol velocities. Just use a good bullet lube and shoot at reasonable velocities and leading should not be problem.

No zinc but you have the other ingrieiants right. The tin when added to WW alloy will help in fillout the mold and is a hardening agent. Antimoney is the promary element that adds hardness to lead. Zinc in casting alloy is a nightmare to deal with quite apart from being lighter than lead.

Take Care

Well I went nuts today...

I don't have a clue how many .40's.... But there are 150 - 7/8 ounce Lee slugs, 100 - 1 ounce slugs and 75 Lyman 525 grn slugs.

I seriously HOPE I don't have to size all the .40's....

Party on!

If that's a LEE tumble lube boolit, you shouldn't have to.
I don't when I load mine.
