I used this to spruce up and charge my Hornady Lock powder dispenser and it did everything I wanted it to. First I cleaned the powder dispenser with a degreaser to remove the factory anti-rust oil and then I took this powder, filled the hopper and drained it back into the container that held the graphite. This makes my new powder dispenser look dirty as hell. But now it works as it should and now I have no issues at all with gunpowder sticking and as a result my charges are more accurate (within 0.1 grains) when I used to have throws that were 0.3 grains could amount. almost every throw. It's not perfect, but imo within an acceptable range of accuracy. This graphite is the consistency of powdered sugar or flour and will leak out of your powder dispenser in places you never expected, so I recommend doing it somewhere where cleaning would be easy or even better, but do it most likely outside it can be very dirty.
