if you really want a top system: https://autotrickler.com/pages/autotrickler-v4 and read at the bottom, they recommend which scientific balance to go with it. autotrickler v4 recommends the A&D FX-120i scale. Brownells carries them. https://www.brownells.com/reloading/powd...0302008005
this setup is what the top F-Class shooters in our club are using. So you're looking at ~ $1500 to get what these guys are using, but they're claiming weighing to the grain of powder with repeatability. I'm sure the A&D scale has recommendations on how to setup and use them to ensure the precision of the scale that's advertised.
more than I can justify at the moment, but it'll solve your repeatability and stability issues.

You can get the A & D FX-120i scale at a lower price than Brownells here:

It's still not cheap at $606.50 but if it lasts many years, it might be worth it.
Added comment: Looks like I should have read the rest of the replies in this thread before adding mine. I see the A & D 120i can be found at a lower price than the one I posted & that another scale (the one at Creedmore Sports) might be an even better choice.
I refuse to be victimized by notions of virtuous behavior.
