There are two ways around 800X's poor metering consistency without weighing charges. It throws consistently through a Belding & Mull measure and, with practice, can be dipped consistently with a hand scoop.

The Belding & Mull measure has a powder chamber that slides horizontally from under the hopper to a dump hole. An adjustable cylindrical measure that is very much like a black powder measure is used to transfer powder to the cases. They are liked by bench rest shooters who do not mind that they are slow. It's also good to have a Belding & Mull as an extra measure for long stick rifles powders.

I make hand scoops by wrapping a piece of stiff wire around a case's extractor groove, twisting it for double the length of the handle then folding it back for a stiffer handle. The case is shorted to throw the desired charge. With a little practice dippers are as consistent as any measure.

I have not used 800X in a long time.
