Place a bullet on a metal plate and hammer it flat into a coin. Look for paint chips and failures. Now Hammer that coin into the cube and recheck for paint chips and failures. Metal fatigue or failure is normal the metal can crack with this test and that's okay. What you are looking for is paint failure and if there is even the slightest paint failure the bullet has failed this second coating integrity test.
