Big rifle loads may usually be ok. Small handgun loads may not.

Most digital scales have the "engine" that is metric. Like anything digital, they dither with a fixed minimum amount, which is usually 10mg. 10mg is 0.15gr, and it is rounded up to 0.2gr. Worst case the indicated weight is dithering among -0.2gr, 0gr, and +0.2gr, but mostly the dithering is on one side. Of course there could be make and model that are native imperial to dither in 0.1gr. But they are relatively rare.
