Have any others tried this? I have and it does eliminate static "cling" and doesn't appear to have an effect on accuracy. The inner portions of the powder measure and powder funnels are a little dirtier with the powdered graphite but that is easily removed with a little tapping. The barrel is a teensy bit dirtier after 40 or so rounds but I clean the barrel after each shooting session anyway.

For those who are willing to experiment a little, this option might be an acceptable alternative to anti-static cloths and washing plastic materials with dishsoap.

Just an idea that works for me! Others might be interested.
