I was having an issue with fine powder sticking to the walls of my LNL AP powder measure. Tried the fabric softener trick which worked on my RCBS and Lee but I think the baked on powder finish in the Hornady isn't that great. It had a tacky feeling to it no matter how much I tried to clean it. I even tried paste wax but it still had a tacky feel to it. I'm guessing the paint was breaking down? Can smokeless powder do that?
I dug out the Dremel and a scouring pad wheel and stripped the paint from the inside walls of the powder measure. Then I used a felt buffing head with some Fitz polish to bring it to a shine. Wiped it down with some alcohol and then treated it with some paste wax so it was nice and slick. I even waxed the baffle and very lightly did the clear tube for the power measure.
I ran 100rnds of 9mm with Titegroup, dumped out the powder and no more issues with powder sticking to the sides.
