We routinely recommend two ways: coffee milling and ball milling. Both ways have advantages. To grind a single chemical (vs. a mix like black powder) using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25% full of potassium nitrate. Turn the mill on and come back in an hour.

How do you calculate speed and feed? Speed (RPM) = (Surface Feet per Minute x ) / Diameter of the Tool. Feed Rate = RPM x Chip Load x Number of Teeth. RPM = Of the tool or workpiece. Chip Load = The amount of material removed, per revolution per cutting edge. Number of Teeth = The number of edges, facets, or flutes.

Stubby, ball end mills are typically used to take light cuts at fast feed rates in titanium and stainless parts. Minimizing tool gage length helps maximize stiffness. According to Mr. Snow, light cuts are also less likely to introduce stress into the material, so parts with thin walls won't "pop" out of shape after machining.
