Does anyone have a sub sonic load for a 150 to 168 gr bullet in 308 Win?

That's a lot of case volume for a very light bullet. Any specific reason to use those, and are you sure you don't want to hit the easy button and use something heavier?
Trail Boss or Tin Star would be the logical starting point since they're meant to take up case volume. With TB follow the guide and work down until you get there. I use Lil'Gun for bolt actions mostly, but I don't like to use it for very light charges like this one would be.

I don't have good loads for those light of bullets. If you go up to 190-220 I have subsonic loads for you. 4895 and Trailboss

That is light bullet even for a 300BLK subsonic load. Heavy (230 gr I belive), round nose bullets and Trailboss as mentioned above were subsonic for me, but pitiful ballistically.

Try this. Hopefully it attaches

Thank all our you
. I'm asking for my nephew. I'll have to get the "bullet ferry " to deliver some of my 190 and 220 Nosler's to him!

I shoot 220 gr rnfb bullets in mine

Bolt or gas gun? Also what twist rate? That's a big factor!!! My 5R won't shoot my 190 plus bullets at all. All key holing. It's a 1/11.25 twist.
My MRAD with the 1/8 twist rate loves the 190 plus loads

Try a 200 or 220 gr rnfb bullet-- they shot fin in my 1:11-- just can't use the tipped boat tail bullets in the slower twists

Just verify because the rnfb was key holing as well in mine. Nothing like a good old baffle strike when you run a can

the SR4759 powder was tough to get about 10 years ago , I don't know if you can even
still get it today .I used it in a reduced 30.06 load . I did use IMR4198 with a 125 grain Nosler ballistic tip in a 308 , for a new shooter .it was pretty accurate , and very mild .
you can try the Hodgdon 60% rule , using H4895 . I've done this with good results .

Hornady 220gr rnfb is 1.283" long @ 1050 fps with a 1:11 twist shows a stability factor of 2.17 at my altitude. Anything about 1.5 should be more than stable
Plenty stable-- tested with no can-- ok, shoots about 1/2 moa for me too.

I agree with the guys that twist is the other flaw of the 308. 300 BLK normally comes in an 8 or 7 twist, and has enough case capacity (without having too much) to get any .308 cal bullet I can think of up to 1050FPS. It's a round with a lot of limitations, but works really good at the thing it was designed for - subsonics.
There are bullets that will work in 10 twist 308s, it'll always be a compromise in the opposite direction - something meant to run fast trying to go slow:
Subsonic Ideas / suggestions
Starting to dabble in suppressed subsonic 308 Win. Since I have bunch of odd ball bullets figured they would be something to start with. My thought was to make the jacketed bullets like wide flat nosed cast bullets. From what read on line so far .250" Meplat 308 bullet at 1050-1100fps should be...
Long Range Subsonic loading
Like to hear anyone's tips and tricks on creating Long Range Subsonic loads. After some my research I would say greater than 100yds. Have been pretty successful out to 300yds with 22LR subsonic so a high BC bullet should extend this range. For me this will be for "fun" shooting for now! Below...
Subsonic long range big learning curve
So far going down my Subsonic long range learning curve , here are some things that worked so far for me. I have gotten to be proficient to 200yds so far. Use quality brass, neck turn if needed for consistent neck tension Short FB stubby bullet works best, use highest BC you can get being...
