Anyone have data or suggestions for subsonic 240 gr cast bullets in 300 blackout?

I currently load the NOE 230 gr cast bullet with 10 gr of CFEBLK for 1000fps.  This should work for your bullet as well.

you can also use 10 gr. of acc.1680 for the same vel.   accurate 1680,cfe blk,,and shooters world blackout all have about the same burn rate.

I use 5 grains of Red Dot or Bullseye for a suppressed SBR upper. Accuracy is good enough for inside 100 yards on hogs, will cycle my AR and gives me full lock back on empty. Of course your weapon will be an animal of its own.
