Using Vibration to Settle Black Powder
For those of you that do not subscribe to the Single Shot Exchange Magazine, I just posted the article at the link below. The article was published in the August edition.

RE: Using Vibration to Settle Black Powder
Wayne,
I started out using a Dental vibrator that was formerly used to "mix"
amalgam for fillings.
It worked great for those early days of bullets seated well into the cases for usual GG bullets.
There was room in the case to dump the powder charge and then settle it with the vibrator.
BUT nowadays with very shallow seated paper patch bullets, the powder charges After Settling are within 0.060-0.070" of the case mouth. Works with a drop tube, but the charge would overflow the case at first before vibrating.
Of course, a person could turn a case extension to hold the powder
until it can be vibrated down into the case.
Meanwhile, I continue on with my 24" helical drop tube.
Works well for me.
The vibrator is still safely tucked away under the loading bench.

RE: Using Vibration to Settle Black Powder
I have drop tubes that range from 4" too 36". The one I use is 12" and it is made from 3/8" OD (not ID)copper tubing with a funnel that has a 3/16" opening glued into the flared tube and it has a 3/8" od X 1/2" ID reducer to fit over the case mouth. I can slow feed it or dump the powder in the funnel and it's like trickling the powder when it's empties. I found very lightly tapping the tube making sure all powder is in the case will raise the powder in the case
The reason a dog has so many friends is because he wags his tail instead of his tongue.

My drop-tube set-up is like Kurt's. A 24" long section of 3/8" copper tube, with a 17 caliber powder funnel fastened to the top. I drop the powder into a weighing-pan, then dump it all into the funnel, letting mother-nature dribble it into the positioned case below. No vibration. I have checked the powder depth in the case and the powder level is within 20/1000 of depth in each case.
Good 'nough!
That's my story, and I'm stickin' to it!
