I've utilize used dryer sheets attached to a pistol cleaning rod adapted to take a 12 ga. cleaning patch holder to wipe the inside of the MEC plastic powder bottle. Also, I've put dryer sheets rubber banded to the outside of the powder bottle; you can still see the powder level as you're reloading. I've also put powdered (dry) graphite on the sheets and do the inside of the MEC powder bottle. No powder issues even when I have other static issues in the house. And by the way, before I ever handle powder, I touch my steel post basement support to discharge any static. Also, I have no carpet in my loading area. That seems to work for me. Now for metalic reloading, I've replaced the plastic tube on my RCBS uniflo powder measure with a stainless steel tube that I had made for me at storage tank supplier. No static with using it; since you can't see through it, I made a gauge to indicate the powder level. Darrell
