That is a great looking set up. After shooting mine, I want another one, but lighter, like yours. Please post picks once you get it. Thank you.

2830fps with 80gr bullets, from a 'standard' 24" 223...hmm...

Any results with RL-15?

Seems my numbers are not reliable from my chrono. I did try both RL15 and Varget with both the SMK 80s, and The Amax 80s. The results were both very equal to one another. The accuracy seemed to be best at 24.8 GN of either at 100 yards. The reason I don't believe my chrony is that I was very careful in loading every bullet as exact as humanly posibble, and I was getting readings up to 80 FPS difference from the same loads with both powders. I think I need a new chrony. Either way, the rifle will shoot both bullets with both powders great. I will be sticking with the Amax bullets.

My next step would be to run your loads with other primers to see what you get. I had a 77 SMK load using Varget that was getting a sd in the teens and by using Fed Gold Medal Match primers brought the sd down into the single digits. But I'm sure you've already done this.

Yes. Federal Gold Medal Match primers is what I used. Thank you though
