Where's the beef?
Ball is stuff like W748. It looks like little spheres or round things.
Extruded is stuff like IMR 3031 or IMR4895. It looks like pencil lead.
Yeah, I know what it looks like.
I couldn't find a quick reference for all of the common powders (similar to a burn rate chart) that says powder Brand ABC Name XYX is ball, flake, or extruded. Might be a nice addition to a burn rate chart.
