I doubt there are many handloaders on Mastodon, but just in case: folks frustrated with the attempt to revive #GRT after Gordon's unfortunate passing might find the Ballistics Swiss Knife useful. It has already replaced GRT in my use case.
I feed published load data from #Hodgdon, #Lyman, #Lee, #Hornady, etc, to BSK. If the estimated pressures and FPS line up I modify the load with my specific barrel lengths, projectiles, and charge weights. Make a ladder and chrono.
Disclosure: I have no connection to the project other than as a user.
Here's the finished device in action. It's used to load primers into a feeding tube, for #reloading ammunition.
A lot of similar devices have a built-in vibration motor. But I'm cheap, and I figure everyone has something around the house that will serve the purpose. A massager. An electric toothbrush. Some other sort of... device... that vibrates. None of my business.

The author announced it in this reddit thread.
I set up a few loads in it and it seems to work fine. Registration required, probably because it allows you to save/edit/dupe loads.
