I don't know but i'm thinking counting out those grains of powder would be pretty tough , especially with my old eyes. It's also friggin' difficult to cut off that final 2/10's of a grain so ya might just round up to .5 and just cut the last grain in half. It's a pain with ball powder though but i'm sure you could rig up a small vise to hold it in place while you cut it to get more precision . But if you round up that way you better check those primers :-) Man what a sarcastic bunch . Jack would be proud !!!
