What factory load 300BLK projectile weights will reliably stay subsonic out of a 9" barrel?

You'll need a specific sub load usually 220gr or up, iirc.  FYI , last I heard though there wasn't subs that expanded very well at the lower velocities. Good for plinking but you may lose a lot for hunting vs supers.

I saw some pics of Hornady 190gr "expanding" subs in gel and was not impressed.  :(
