If I sit on a five gallon bucket it puts my eyes level with my beam scale. And I'm lazy.
On a beam scale, I set a web cam on a box of bullets facing the scale. I run the cam to my computer, and watch my computer while trickling. When you move your head the readout on a beam scale looks just a touch different. The web cam doesn't move, so it fixes that problem for the price of a 10 dollar camera.

EDIT: I just realized this is about reloading. Nevermind.
