Working on a gadget to alarm when powder level in the hopper is low and also estimate how many grains are remaining. I have measurements for Dillon and Hornady powder measure hoppers, I have a couple Lyman units downstairs that I'll measure, I don't have any Uniflow powder measures any more though.
Anyone with a Uniflow powder measure, would you measure the outside diameter at the top of the powder measure hopper?
