CABL lead is homogeneous up to a melt
(a few tons). Differences are first found
between melts.
MC lead is heterogeneous within a bullet,
but melts are indistinguishable.
Huge qualitative difference.
CABL lead becomes heterogeneous at a
ton or more, whereas MC lead is
heterogeneous at 0.1 ounce.
The two types of lead are entirely different.
