My guess is light charge or no charge first and then second and even a contributing factor could be the "tightness" of the barrel. Have you ever swagged a lead bullet down the barrel to see what the dimension your barrel is? I have seen some tight ones and have re-loaded 9mm bullets in those in the past. I would say older .38's had that issue mainly.
Every charge checked with a digital scale and every few charges spot checked with a RCBS 5-0-2. Then all cases were visually checked (with a flashlight) prior to seating.
