Nice shooting, considering the conditions, ammo, etc.
I believe standard US 5.56 ball ammo is only required to be accurate to something like 2 to 4 MOA, so I don't imagine the AE223T will be too different. Handloading will definately help some. There are also a few factory options.
Something else to consider, its to pick the target to match your optics. I have targets designed for use with my 2MOA Aimpoint PROs, as well as Leupold CQTs, and it does tend to make a difference, for me anyway.
As for triggers, ArmsEast has some Geissele Triggers in stock that may be just what you want. They have a very good reputation amongst AR users.
