Tests done previously on dry, clean pre-sized projectiles , showed that the coating will not adhere to alloy even if clean.
It seems, that during sizing, the alloy surface becomes sealed and the coating has nowhere to penetrate and stick.
If during sizing, if any lubes are used, like waxes and other, it would also cause coating to not stick to alloy.
Rinsing with solvents, may clean metal from lubricants used during sizing, but also, not completely.
Unless projectiles are vapour de-greased, I have doubts that in many instances, all lube components can be removed, unless solvent washes are done many times.
