Nice to see another 1:7.5 16" option.
Since you asked about ABLR loadings, my current 129gr ABLR load for my 16" AA upper is 30gr of CFE223 at 1.648 BTO. I don't know the exact COAL but it fits in an E-lander Grendel mag. CCI 450 primers in Hornady brass. Leaving the barrel at 2365 fps, SD in the mid teens. The best I could get out of this combo is about 1" to 1.25" groups at 100 yards, which is perfectly fine for me since I consider this a hunting load.
After I burn through these though I'd like to try using AR Comp instead, the CFE burns dirtier than I like in the rifle. I also expect the velocity to drop a bit if fired in colder weather, since CFE223 is a bit temp sensitive.
