Well when they ask about SST's that alone means they are the Hornady offering of the bullet. The "Shockwaves" are the Thompson Center brand. I have SST's with a yellow nose. I started shooting them because of some comments Lee made about them a long time ago. He was not wrong. Super accurate I can say. And while I have yet to shoot something other then paper, if they do as Lee said... I would be real happy with them.
