— Yes, coating your grains in graphite actually reduce performance Graphite on it's own will slow the powder a little bit. The processing that goes into it, further slows the burn rate. Only sporting powders are tumbled and coated. This smooths the surface, removes the sharp edges, and makes the grains more uniformly sized.

This is what gives you smooth consistent lines when you hold a pencil and drag it across paper. Because graphite is soft and brittle, a casing is required to hold the material. Artists use graphite, not just in pencil form, but in powder form too. In powder form, graphite can be applied to paper using a brush, sponge or tortillion.
Commercial battery-grade graphite powder was bought from Sigma-Aldrich. Recycled graphite powder was subjected to ball milling for various times using a Retsch PM-100 ball mill employing a zirconia grinding bowl and ϕ 10 mm zirconia balls. The ball-to-powder mass ratio was approximately 20: 1, and the rotation speed was set at 400 rpm.

— That's when I spotted my graphite powder and thought that would probably work its way in with a few spins. (Giving an oldish pram a quick makeover before gifting it to my friend). My question is, do I need to try and remove the WD 40 before sprinkling the graphite. Don't want to clag it up.

— graphite powder is still a solid... you might as well use talc. if your bearings are higher precision than ABEC 5, even the tiniest solid particle will jam them easy. ball bearings are best lubed with light oil, nothing else (after removing factory grease) plastic gears can usually be run dry, its better than exposed greased gears collecting grit.

— I have balls I cast maybe 20 years ago, and they remain in the unopened jars, nice and bright. But if you are in the habit of often opening the jars to remove a few balls, you are putting fresh oxygen into the system, and the process begins anew. It works for long term storage, which is why I use smaller jars, holding maybe 8oz by volume.
