Abstract
This disclosure generally relates to high-volume and cost-effective methods for producing non-spherical metal particles, particularly methods for producing metal cubes having rounded edges. The metal cubes having rounded edges are useful as ballistic shot in shotshell loads for hunting, where the particle shape imparted by the disclosed process packs to a higher density than spherical shot in the same volume.
