Powder sticking in powder measure

[DMF13]

I guess I'll try adding a ground wire.

I used half a can of that stuff on the powder drop parts, and wiped it all down with microfiber towels.

Sounds like you got that covered.
I can only wonder about your climate?
As an alternative approach, I did buy some of these vibrators and battery holders but never followed through to try them.
I know some people use aquarium pumps attached to the measure.

I have one hopper that I use almost exclusively with W231 for handgun loads. It is approximately 25 years old. The plastic is covered with stuck W231, but it is not stuck to any of the lower metal parts. My throws are always consistent, but yeah I really should just replace it. I’ve cleaned it before and as soon as you fill it up it sticks again.
