It was designed to be a subsonic round. My SBR with a 9inch barrel, jp capture spring, and omega suppressor is stupid quiet. The capture spring really quites it down a lot. Really the only thing you hear is the bolt going back and forth. I am shooting 220 gr Hornsby super performance with 11gr of accurate 1680. I am at about 1000 ft per sec.
