frater musI 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.
