Thread: 1:7" twist 308 Who's running a ultra fast twist, super sonic and why ?

a mini-action on the other hand...

If you want to run subs (which for better or worse I seem dead set on trying) the best powder option for 308 by far is trail boss.
With the availability of it currently being terrible, and it only forcast to get more scarce, it's not the best option if subsonics are on the menu.

Yeh I'm down to my last 2 KGs of Trailboss so I will keep it for my
25 rimfire
32-20
38-40
44-40
And a few other modest old cases it really shines in

Yep. Trailboss works indeed very well for subsonic loads for 308. Was lucky to be able to get some and am set, but i see what you mean.
