Johnny, all I can tell you is that after being fully embarrassed by several boxes of shells, many of which sounded like a flock of ducks, and having to remove numerous wads from my barrel, I went home to cut the leftovers open, finding anywhere from a few flakes of PB to a full charge inside. A search for the cause led to my 9000G and a glance in the bottom of the powder reservoir showed me that the red plastic baffle was now black inside. An LED light confirmed that the black substance was in fact powder.
Suspecting an electrostatic charge, I connected a ground wire to the wall outlet near my loading bench, touched it to a bare spot on the loader's base and the powder disappeared into the bushing. I then permanently connected the ground wire to one of the bolts attaching the loader to the bench, tossed the baffle in the trash where it belonged and have never had as much as flakes on the inside of my power reservoir.
That was many years ago and I have not had even a hint of static buildup since then. And I now don't have to ground my loader as I have it bolted to an Automate.
Some time after that incident, an industrial electrician with whom I shot trap and I were discussing reloading and I mentioned my discovery to him. He was only surprised that I wasn't expecting that to happen. Since then, I've spoken with numerous shooters who had similar experiences.
