BRAVO Dahermit!!! Yes!
A properly powder-coated projectile can be flattened on an anvil and the coating will deform with the projectile. It won't chip or flake. - So not paint.
Indeed a powder-coated round needs to be run through a sizing die before it is loaded or, due to the coating properties, it will likely be too large to chamber properly and will jam in the chamber. If it were just paint you couldn't run it through a sizing die and still have a PC'd round to reload.
