I've never been to a benchrest match, but my understanding as well is that the boys who shoot for one hole groups don't weigh, they use a volumetric measure. And, just because electronic scales may read to .oooFA, doesn't mean they are either accurate or consistent to .05 grains. The number of digits to the right of a decimal are determined more by marketeers than engineers.
