I have a Satern Liberty 20" straight fluted stainless steel barrel with their available headspaced bolt. I'm using 123 SSTs with 28.0 grains of IMR 8208XBR, both Hornady and Federal brass, Federal Match AR primers and a COAL of 2.266". The average velocity is 2545 fps and I can get 0.5 MOA if I do my part.
