Satern Powder Funnel Aluminum Static-Free 50 Caliber

At first I was very unhappy with this funnel. Powder kernels would get stuck at the bottom and wouldn't shake loose. I had to literally scrape them out with a Q-tip. Was looking into returning it but decided to read other people's review of these funnels. One reviewer held the key! Apparently they can have residue on them that will stick to the powder flakes. He used acetone and a cotton swab to clean it and then said it was great. I used denatured alcohol and a Q-tip and low and behold!! Powder flowed through it like water with no sticking stragglers. It's been fine ever since. So 5 stars........just clean it first!
