You can usually get spherical powders to throw ±0.1 grain or even better, but everything else will normally spread out a little more. After checking every fifth round, when you get about 30 of them, find the average. That's where your measure is actually set. Adjust accordingly, so half the errors are low and half high. That'll keep you closer to what you want.
