The simple fact that ALL loads given by published sources (books, manufacturers' websites, etc.) are expressed as grains makes the use of milligrams by anyone to be much less than acceptable, useful, or accurate. It's almost like saying that "I have a 250,000 square inch lot which my house is on" rather than the equivalent in fractions of an acre (a unit everyone understands). Give us a break, already. Or, get really squirrely and use an analytical scale, calibrated in micrograms, along with its microgram weights. And wait five minutes for each weight check.
