I use a Hornady powder measure for pistol reloading. I can get it consistent enough once the powder settles in the hopper.

I use an RCBS ChargeMaster for most bottlenecked cartridges. It seems more consistent than my powder measure for larger powder charges. Especially for stick powders. However, I’ll use the powder measure and trickle onto my 5-0-5 if I’m going for best accuracy.

Electronic scales are only as good as your calibration weights, if that.The first ChargeMaster was garbage for consistency and went back to RCBS. I’ve used the second one for almost 20 years. I did buy certified weights for calibration because the 2 that came with the device were slightly different from each other.

There is no substitute for using check weights, regardless of what scale you are using.
