I have a Lee mold that needs to be dropping a little larger than it currently is. After much reading around here, I think this thread is what I'm going to try:

Is there somewhere local I should be able to pick up a small quantity of abrasive powder, in the 180-220 grit range? I figure that will expand and then I can just use toothpaste to polish the cavities back up.
Everywhere I look I can only find paper- or cloth-backed abrasives. AKA sandpaper. We have Lowes, Home Depot, and Ace here.
