You actually found some old AMAX and not the new replacement ELD-M?
I've shot limited amounts of both factory offerings and both were easily sub MOA.
I've done a fair amount of reloading with the ELD-M (chosen because I knew that projectile would shoot) and I keep flirting with breaking below 1/2 MOA. I got horrible velocity ES on the low end of the powder charge scale but good accuracy and ES once I got to the midrange and upward. I was using H1000 and if I were starting all over I wouldn't even bother with anything below 84 grains.
