I use a Chargemaster for all of my precision loading. I wanted to see how accurate it actually is. I know if you have a good solid mode, it’s not sensitive to minor variations. Anyways, it occurred to me that the beam is very accurate. However, judging the gap is hard. So I glued a sewing pin (minus the plastic doohickey) on the actual zero line extending it towards the beam. It is incredibly easy to make sure the beam is right on the point. Kinda like the Prometheus. Bottom line, the RCBS was close all the time but it seemed to throw heavy and light charges of the same weight, if that makes sense. Thought someone might can benefit from this.
