Hornady lists 31.7 grains of CFE 223 as max load for ARs. At 31.5 in my gun with COL at 2.360", I had no issues (more room for powder, but closer to lands than AR gun). YMMV. I purposely did not post this in the Reloading section since I don't want anyone to transfer what I did directly to their AR. Start low, and work up.
I consulted quite a bit with a very experienced and knowledgeable forum member before striking out.
I've included a pic of the center points of my OCW groups (3 shots each charge weight). I basically chose between charge weight 3 and 4 as a likely node candidate.
