Looking for subsonic 300blackout loads (bolt gun)

[aubie515]

I see a lot of information about subsonic loads for 300BO, but what I need are some loads for my bolt action.

Rifle specs
1:8 twist 16.5" barrel.

I'm hoping someone has loads for 168,175,178gr projectiles as that's what I have on hand.

Has anyone tried using Trail Boss? I know it won't cycle AR15s, but was thinking Trail Boss or Lil Gun for powder.

Thanks in advance.

220 Sierra BTHP, 8.5 Lil Gun, 2.590 OAL, works awesome for me in a 16" 1-8.
