I dont coat.

I dabbled with it a bit probably 20 years ago with colloidal graphite dag suspended in alcohol. This required literally painting the bullets, but worked the same way after it dries.
It works similar to mold prep.

Dropping them out of the bake is actually annealing/drawing them a bit; the temp to bake isnt high enough to treat the metal and is actually softening it.

I use a 200WFN for the 10 mm, heat treated to 28 BHN dropped from the mold.
I use AA9, but dont recall the charge.
