Most standard 147 grain are subsonic. There are also commercial subs available. Bubba Kitty (formally Tomkat) is good people. Andrews subs are decent. Ne er had an issue with them. I tried 308 and 223 subs from him as well.
What host and can are you using?
985 FPS 147g Speer Lawman FMJ and Gold Dots HP. I'd figure all 147 non-plus P 9mm would be sub-sonic.
