I recently purchased a new 17 Caliber RCBS powder funnel to better load 223 cases with H335 powder. My older RCBS 22 to 45 caliber powder funnel was just not small enough and leaked powder. The trouble I am having with this new funnel is the fine spherical H335 powder sticking to the surface and I can't seem to tap it enough to get it all down in the case. Does anybody have a solution for this sticking powder in a plastic funnel?
