I have been using a Lee PPM for over a year. Yes it leaks a little with fine powders. Not a whole lot. I put a sheet of paper under mine, and weighed to see how much leaked out after a loading session with Bull's Eye which seems to leak the most. 400 charges thrown. It leaked a little over 1.5 grains. I would buy a different powder measure, but mine still works well. It meters Varget to within two tenths of a grain, usualy being closer to dead on most times. Pistol powders like H-110, Bull's Eye, TiteGroup, and Acurate#9 meter to dead on every throw. The only powder I have used that does not meter well from it is Hi-Skor 800x which is known for not metering well from any volumetric powder measure.
