CUP-8 Atomized Copper Powder is used to make non-lead bullets with a density
about 2/3 that of a lead core bullet. The copper powder
compresses well under moderate swaging pressures, and
forms a solid that can be handled. Typically the powder
is compressed inside a bullet jacket. If not, the compressed
bullet needs to be sintered (heated in an oven to fuse the
grains together). It will then shrink slightly, so the
original swaged bullet needs to be made over-sized. Exact
diameter control normally comes from running the sintered
bullet through a draw die as a final step.
