This discussion so far does not address the issue of whether an error of 0.05gr in a 55gr rifle charge is significant to accuracy. Varying humidity from a wet day to a dry day can cause error as much as the scale. As far as breezes, beam scales are at least as sensitive to wind currents as are the electronics. I've used the ultra-accurate lab beams in the double boxes that can weigh my signature.
This questiion is relevant, especially considering most bench rest competitors dip their powder charges when on the line, and don't weigh them at all.
