A 20" barrel should be getting in the 2500fps (762ms) area with factory ammo, so finding the right powder is the task. I have not read anyone getting north of 2600fps with an AR and 123s. Mid 2400s to low 2500s.
My 24" Lilja barrel finally picked up some speed and shoots 2508 avg with my reloads that are a little hotter than Factory (Factory ammo shot in the low 2400s when I first got Lilly) She runs slow as it is.
If you can duplicate the ES and SD, and groups well, then stick with it.
