My .223 is not an AR but it likes 65gr Sierra GK, fed case, fed 205, 28.0 gr of H380. Chrono's 2,800. This powder is a bit slow for general use in the .223 except with heavy bullets.
I've shot an unknown number of hogs with this load, most all head/neck shots.
I've shot 5 WT deer with this: 3 head shots 2 with lung shots. The lung shot deer required 2 shots each. The bullet mushroomed beautifully with good weight retention but stopped under the hide on opposite side. Not a good deer bullet IMHO.
