I will flag the 208gr or heavier.
Will stick with the 150gr ones. And then leave it with the 8.5gr trail boss at 1040fps.
Might have to modify slightly with cast projectiles but not by much if any

Has anyone tried using 2205 for subsonic loads with the 208gr projectiles in 308.
Trail boss didnt work so I might try 2205 cause it worked in the 300blkout

I'm hoping for mine to be a dedicated subsonic rifle.
And supersonic as a secondary option

I will have a 260AI and a 6.5 creedmore for any hunting requiring higher velocities

No you take the suppressor off and test to see the projectiles dont tumble. If they tumble they could hit the suppressor and damage it.
Once they shoot straight and dont tumble, then put suppressor...

I think mine is 8.5gr for the 150gr which gives 1030fps.
Haven't chronographed the 174gr ones yet

aetchell I will give you a start point with mine, but your barrel length and wear will show different speeds.
Most factory subsonic loads were for the short barrels on ar15s and were supersonic in...

Tested the loads today. The 208gr subsonic tumbled but did group at 25m. The supersonic 208gr ones worked fine.

The 150gr flat tip projectiles plus the 150 cmj ones worked as usual. ...

Not yet. Was getting there but there was the lockdown so haven't got anywhere yet. Had issues with them tumbling so need to sort them out first.
Have some 150s loaded up to see if they stabilise

I've been lucky so far with the 300blkout. They tumbled but luckily didnt hit the suppressor.
Will load some up and shoot to see if they tumble. Then I will shoot through the chronograph to...

I realise each rifle is different but im after a starting point for some load data for subsonic loads in the 308.

Im after some loads for the 208gr and 212 projectiles I have if they don't sell.
