I am having some issues with my MXX-123 drifting on me. Last night I was trying to do some loading and I was having to re-zero after each round. I have had issues in the past but nothing this bad. I do have the scale in the garage, but we had no wind and moving my hand around didn't seem to make it move either. I do have it sitting on the bench will all my other gear so maybe my powder thrower moving makes it freak out? I do have it plugged into a line conditioner and the temperature was in the low 60's upper 50's. Also, I have it programmed for "very unstable". Anything else to try?
