I have a few that I made with 22lr cases .
Fill with lead and then drill some out.
If You remove too much a shaving of lead and a bit of heat and your back in business.
I tend to push my case down into the powder then scrape of the top once On a bit of straight wire stuck through my powder bottle near the top.
Seems pretty consistent.
1" or 25mm micrometer shaft might work a treat. They are 1/4" roughly in diameter.
Ohh yes.
Some shiny brass and ss.
Or just a nice ebony handle brass dipper from Harrods and an accompanying silver powder container.
All in a green felt lined Compartmented box with other implements.
Fetch my loading box Jeeves!
