>Machining Fundamentals: Introduction to Milling Tools ...
Ball Nose Mills have a radius, a hemisphere, or half of a ball (which is where it gets its name from) to give it a rounded end instead. Now there is a type of tool that lies somewhere between these two, which can be called a Bull Nose Mill or a Tip Radius End Mill, which has a partly flat bottom with a radius just around the edges.

>Size Reduction - an overview | ScienceDirect Topics
The size of the milling media (typically 20:1 for ball:powder diameter) also influences size, morphology and microstructure of the powder. To produce fine powders, it is recommended to mill in several steps while reducing successively the milling media size, as one milling step usually induces a particle size reduction of about factor 10.

Ball milling wet definitely mitigates the risk, but if you mill it dry I give it a pretty dang good chance of going off. That being said, @Katie, the fibrous nature of NC seems to lend itself to being more energetic. Lacquer grade NC is very powdery, whereas propellant grade NC is typically very fibrous like wood pulp. By milling the smokeless ...
