I hope you mean 20 and 30 grains.

No, I'm pretty sure he means grams - my PACT digital came with 20 gram and 30 gram weights. I wouldn't really call them check weights; they're intended for use in calibrating the scale, and at one point you actually put both weights on together to give you 50 grams. I'd hesitate to "check" the accuracy of a scale with a 20 gram (= 308.6 grains) weight and then proceed to use the scale to adjust my powder measure to throw, for example, a 10 grain powder charge. Much better to check the scale with a weight close to the charge you want to throw.
