Years ago, I read that rolling the necks of military rounds between two steel plates would break the sealant so that bullet pulling would be easier. I remember trying it on some US Ball ammo, using a flat plate on the bench and the edge of a piece of 1/4" plate to roll the case back and forth - was able to use either the press collet type puller or the inertial puller with a little more than normal effort to pull the FMJ's.
