Semisane
you can load 10 with 80 grains of powder, 10 with 90, 10 with 100, and 10 with 110, and be good to go for a range experiment with whatever bullet you're trying.
Just remember if you do that you can not leave the powder stored in that clear container for an extended period time... UV will deteriorate the powder... that's why powder comes in the opaque bottles or rupture cans - "no light"
