I enjoy experimentation. I started PC'ing a few months ago, and the first few batches were done by placing the boolits in quart freezer bags and then into a vibratory case tumbler. This worked good, but after some thought and reading here and other forums, I began to wonder if the electrostatic principle could be applied another simpler way.
I dumped 150 cast .357 boolits in a quart bag, added a couple of teaspoons of Harbor Freight Red, sealed it up, and then dragged it over a piece of carpet that lies in front of my loading bench. 30 seconds of dragging it back and forth (picture cleaning the carpet with a scrub brush), then a little hand tumbling of the bag, then another 30 seconds of dragging. I repeated this for 5 minutes, then dumped the bag onto a screen colander placed on a plastic tub to remove excess powder. I cooked them as usual, and they looked as good as my earlier batches.
That same static that snaps you after walking across carpet seems to attract and hold the powder in a similar manor as adding airsoft BB's.
