The bullets from Berger and Norma are something else again. The coating they put on does not come off unless the bullets are tumbled in pin media, which isn't good for the bullet.
I've found that the SS pins in a RCBS Sidewinder is the fastest and best way to remove any bullet coating (I've been using moly & hBn for @20+ years) - the Thumler tumbler does mushroom the tips.
