You're down in 300 Blackout territory, maybe you could start with that loading data.
Here's the Trail Boss manufacturers (ADI) data:

Just noticed there's some old threads listed at the bottom of the page, one of which you started:

Yeah... been a while tho..
13-15 grains of Trailboss will be subsonic or close with the 208 AMAX in .308.
At sea level, stability is iffy in a 1 in 12" twist, but a 1 in 10" twist should work.
There are a few tricks to working up and shooting subsonic loads. TB often has issues keeping the velocity consistent. It's fun to play with, but accuracy and consistent velocity are challenging, especially the 1st shot form a cold barrel and getting things to settle back in after cleaning.
