I have used a Redding 3BR with both micrometers for over 20 years. Zero problems and very repeatable. So for handgun you can't go wrong with this, but they are not cheap.
I added an RCBS ChargeMaster 1500 powder scale and dispenser combo about 2 years ago. I wanted the automation feature for rifle loads and the electronic scale gave me more capability. It has performed flawlessly during that period. I use the scale to weigh brass to sort by internal volume. But, it doesn't work very well with low volume handgun loads.
For easy to measure ball type powders the volumetric Dillon RL550B measures work very well.
Before I got the Redding 3BR I used a Lyman 55 powder measure, but was never happy with it. Looking back, I don't think I used the 3 adjustments properly to use the measure in the best way.
If you use long stick powders, you are going to get some shearing with any volumetric measure you use. Minimizing the opening size will reduce the shearing you encounter.
