I have been using an RCBS Chargemaster for the last 4 years and today as I am loading, instead of slowing down to trickle the last few grains, it ramps up to max speed right at the end throwing a big overcharge every time. I have tried restarting it, unplugging it, throwing different weight charges and recalibrating it with the test weights and it still does it. Has anyone else had this problem? Also, if it is messed up, does RCBS cover it under warranty? Ive got some matches coming up and need to load about 250 rounds in the next month and a half and the thought of having to go back to a beam scale makes me cringe.
