[QUOTE="kstrick, post: 341280, member: 11227"] OK guys. I had my powder charges weighed by a commercial grade pharmaceutical research scale. My RCBS Charge Master is weighing dead on. One weight was 45.5 gr on the ChargeMaster...pharmaceutical scale 45.53 gr. the other was 52.3 gr on the ChargeMaster ... pharmaceutical scale52.22 gr. So..we are talking about less than part of a single stick of IMR 4350. There is no way a balance scale can match this. Now that I know the scale is right on I have to figure out what else can be giving me the velocity variations. Maybe it is the chronograph. gun) [/QUOTE]
