Check. Drop them hot, right out of the mold into ice-cold water.

Look for Linotype, it makes brilliant bullets. Check with newspaper
printers and ask them how they dispose of their waste, you
won't regret it. The bullets will typically cast about 8% lighter than
pure lead. They can be used to 1800FPS without gas checks
and not cause barrel leading. If I remember correctly, lead is around 9
or 10 on the Brinnel scale and Linotype is about 28/29,
which is considerably harder. Linotype bullets are much better
penetrators and do not deflect off window glass like lead bullets
do. Don't ask how I know that.

And if you cast wheelweight bullets and dump them directly into a 5
gallon bucket filled with water,


I take it, you do this hot, as in right out of the mold?

then size and lube them within a day or
so..within the next 7-10 days..they will harden up to around Bn 30 and
stay that way for up to 4 yrs..after which they will slowly soften back
down to 13-15
