Digital scale nightmare.

to me a powder grain is a single kernel of powder, but I suppose by saying grain it could get confused with the measurement system being used (grain system)

Maybe use the word "granule" in lieu of grain or kernel? That's what came to my mind. A kernel is something that's at the center of something else, strictly speaking.

Interesting discussion. I had no idea about boards and such in these things. Then again, I'm also happy to live with +/- a tenth every now and then. When shooting at longer distances I figure they're must be factors affecting trajectory and flight path that eclipse being off by a fiftieth of a grain. Just my own POV. Please continue.
