I shot a 10 round group at 100 yards last range trip to test the accuracy of AE's new loading advertised for M1A's. The ammunition was pretty accurate for the cost.
I shot the group from the prone off bipods with my R700A5. For reference the ammo shot .5 moa lower than the factory Hornady loading of 168 OTM. The "stray" round was not a "flyer". It felt the same as all the other shots and I was surprised to see the one round impact .6 MOA away from the center of the group.
Even if the vertical deviation of that single round proved anything, I'd still buy some to test in your Precision AR10's. It's a good load for the price.
ETA: I didn't realize this picture was so blurry, oops. That's a nickel next to the group lol.
Please don't buy it all! I want a couple more boxes first.
