Using Vibration to Settle Black Powder

[beltfed]

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.
