The issue it appears with any powder dispenser these days appears to be accuracy versus speed.
Electronic scales today read at levels we never would have dreamed of 40 years ago. This unfortunately causes people to obsess about needless things
When we try to keep a charge within 1 kernel of powder, we complain about the system. Granted, my old beam scale could show this, but how accurate was it really?, I have no idea because i never weighed those charges from all those years ago on a modern electronic scale. My loads still work, but I don't spend as much time trickling each charge since moving to electronics.
What is the real difference in 1 kernel of powder?, Are there other things in your loading process that are causing more issues? Very Likely.
Are you measuring individual case volume to see if if one more or less kernel of powder makes a difference? Are all other aspects of your case prep, bullet bearing surface, etc. all exactly the same? If not, you are chasing unicorns. We have too much technology, way too much extra money, and not enough common sense in our sports in my opinion.
Now, lets ask the real question. Are you able to shoot the difference? Unless you are in the top 1% or less of shooters, I say quit obsessing over your process and spend more time pulling a trigger and learning. You will likely spend less time and money doing tedious tasks and having a lot more fun. You will also likely get much better results. Most peoples reloading efforts outweigh their ability to shoot but not their wallets these days.
I use an ST and while it is not without issues, it works for those who don't mind playing with the vast number of options. Is it the best? Only to those who say it is.
IMHO
