I am about the buy 1000 "AAC 5.56 NATO Ammo 77 Grain OTM" but I have no idea if they "shoot well" in my 223.

I have not shot the 77gr otm, but I have put about 500 of their 75gr bthp through my .223. The 75's seem to do pretty well for the price. Ten round groups about 1.25-1.5". I chrono'ed 26 rounds today, ES of 110fps SD of 27fps.
 
Another option for 77gr ammo, @h2so4 provided some Bone Frog .223 ammo loaded w 77gr hpbt for testing. My Tikka liked it… 18” barrel. Avg 2615fps. Max spread around 50fps over 20 rounds.
Shot 10 fairly quick, checked group
Shot another 10 faster, checked group
0.2 mil Right adjustment
Plugged in a BC of 0.350 and walked it out to 600, windage missed 1st shot at 6, corrected and no drama.
I believe those are loaded with the Barnes match burners. A buddy of mine shoots those through his 18” gasser with great results.

Yes Barnes. I was very impressed, for a factory load. , I wasn’t shooting slow on the second set of 10 and honestly wasn’t waiting for a perfect picture through the scope, just to say the 20 rounds group could have been smaller.
 
I wish those match burners had a better BC. It’s only .349, while a TMK is .418 or so
