Empty your powder bottle of all powder and either roll some shot around in it (make sure shot has been coated with graphite), or sprinkle a bit of straight graphite into the bottle and swirl it around to get rid of the static charge.
Adding a bit of humidity in the air, for those of you in the drier areas, will help cut down on static electricity.
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
go to Radio Skack and purchase an Anti Static strap and use it when you reload. It worked for me. I had so much static electricty in my house I was afraid to touch my reloader in fear of a spark would igniting the powder. Ground the reloader and ground yourself with the strap.
The static in the bottle don't bother near as much as it does in the hulls! Static in the hulls help that flying powder burn them up much faster during ignition. I now store my hulls in cardboard boxes along with a few of those dryer sheets and it helped a lot. Hap
