Most folks will size after coating, so I am somewhat against the grain here, but if my bullets are sized the way I want them, I don't see the point in sizing after lubing...which is what PC is, so I am more concerned about the pre-coated diameter..
I think .002-003 over bore is ideal, but as long as the bullet is big enough to seal and grab the lands I don't see that it makes much difference otherwise.
Try using the Black plastic airsoft BBs for a more even, heavier coat.
