300BO subsonic loads

[fullstream]

Anyone have any loads that you could recommend? I have H110 & CFE blackout currently. What bullets? Mainly for plinking.
Looking for any and all advice.
Will be shot out of ar with a 16" barrel and a banish 30.
Thanks Steve

Here's some loading data for subsonic 300blk. There are several options for those powders. It will depend on the bullets you'll be using. I've used those tables when loading 190gr, 200gr, 208gr, and 220gr. All loads have been subsonic and worked great.

My son is trying to work up something for his 300bo.. using CFE and 180g Berry bullets. Will let you know, unless he blows his gun up, as he knows everything and doesn't need advice

LilGun is also a good powder for the 300 blkout I believe
