Heat Treating of Lead and Lead Alloys :: Total Materia Article
Adding sufficient quantities of antimony to produce hypoeutectic lead-antimony alloys can attain useful strengthening of lead. Small amounts of arsenic have particularly strong effects on the age-hardening response of such alloys, and solution treating and rapid quenching prior to aging enhance these effects.

Hard cast bullets can be formulated of numerous alloy mixes (antimony, silver, tin, etc) containing some lead, but the alloys make the bullet much harder than pure lead. Pure lead has a Brinell hardness # of about 4. Most hard cast bullets will have a Brinell hardness # of 11 to 30 and as such are several times harder than lead.

Not to likely as deeply set as these terms are that it will change but to understand how a lead (Pb) antimony (Sb) alloy is "hardened" the correct terms must be used. What we are doing by heat treating or quenching from the mold is changing the grain boundaries within the alloy, one way to greatly enhance this effect is to use a "grain refiner".

H, or hard, leads are tightly compacted and contain more filler, which causes them to make the lightest lines, as only a tiny amount of graphite is released when the pencil is used. It takes a lot of pressure to make a darker line with pencils in the H category. At the other end of the pencil hardness scale is the B category.

Pure lead is 5BHN. Antimony adds about 0.9BHN for every % in the mix. Tin contributes very little to hardness, it adds 0.3BHN for every % in the mix. Its purpose is to defeat the surface tension of molten lead so that it fills mold details completely. Almost unanimous agreement is to mix in 1-2% tin. Pewter=tin, if you can find it.

Pure lead is often described as "dead soft". For all practical purposes, pure lead can't be hardened. To increase the hardness, other metals are added to lead to form a lead alloy. Adding tin will make lead slightly harder, but a lot of tin must be added to significantly increase the hardness, and this has two adverse effects.
