Hello Folks I have just received my new mold for my 300 Blackout it is a double 309- 210 gr hollow point from Cast Bullet Engineering, I am on the hunt for subsonic loads I will be using them in my Rem bolt action 1 in 7 twist, any help would be appreciated.

Give Accurate A1680 a try, in the neighborhood of 11 grains @ 2.20". I use this load in my 1:7 8.3" 300 Blackout. These have enough gas to cycle the action on a AR style rifle.

I am running 9.5 grains of CFEBLK with a 230 grain NOE cast round. Runs right at 1000fps.

In a bolt gun I would try a fast powder like bullseye or Unique. You dont need a powder that makes a lot of gas for an AR.
