Given all of this new info I think I'd do this. I'd check the crown, or have a trusted smith check it. If that looks okay I'd try a proven scope. If that doesn't change anything I'd try pressure bedding the fore end. That's what I would do because it looks like you've done the work trying different loads. I hope that helps.
I actually just got in a new Vortex diamondback tactical 6-24x50 that I plan on swapping on it. I want to put the SWFA on my AR10. Maybe that will change something. I hope I don't have to pressure bed. Did a crap ton of work free floating the fore end of the rifle.
