I have been told 300 AAC/BLK is available in Super-Sonic. I have only seen Sub-Sonic labeling. Is Super available? How is labeled? Not counting current shortages, where can I get the fast stuff?

Paul F. · Answer

That is Supersonic ammo you linked to, supersonic is supersonic because your projectile is smaller /lighter (110gr, 125gr, 150gr) then your subsonic us bigger/ heavier (180gr, 200gr, 220gr) typically if its not labeled subsonic its supersonic
