Kept searching and found this idea:
You can also make your own using a regular funnel, copper tubung, a flaring tool and a hot glue gun.
select the right size tubing that fits the ID of your funnel, you can trim the funnel to enlarge the hole if desired. Cut the tubing to desired length. Use the flaring tool to flare one end of the tube. Insert the tube, with flare on top, through the funnel, in the direction of flow. Put a little hot glue under the flare to seal it to the bottom of the funnel, Then flare the other end for your case mouth.
Also bumped into several threads were guys used the vibration of their tumbler to shake the case. One guy said he used an old elec razor.
I have put my finger over a case mouth and gently tapped it on a hard surface to settle powder a bit deeper.
