I use the same setup except the scale is a TRX-925 ($374.95 at Creedmoor Sports so it's over the OP's budget). The Chargemaster will drop up to a 1/2 gr high every now and then, and show good. I think powder falls out of the tube after it thinks it's done. Sometimes it tries to add a 1/10th and it over drops. Sometimes the Chargemaster's scale says it's dead on and it's not. It's good enough to drop with. Like digital mic's and calipers the 3rd digit of the TRX-925 isn't all that useful.The Creedmore Sports TRX925 is right up your alley. I've had one for over a year. Measures to .001.
