I bought an APC power conditioner (noise filter /surge protector/voltage regulator)for the RCBS Chargemaster.... decided to weigh out some powder and see the variability.
Frankly it was amazing in that with the power conditioner and tweaking the settings of the Chargemaster (see the many other posts) I wound up more or less at +/- a single particle of RL 25 in 50 consecutive throws of up to 100 grains. It wasn't that bad without the power conditioner but 10% of all throws would be off by 0.1 to 0.3 grains ...most at the lower end.
I bought the conditioner for the stereo set up. Much better use now!
FYI. I paid 100$ online
