In regards to the 223 and 53 gr Vmax, I couldn't get them to shoot in my RRA Coyote AR rifle. I used AA2230, Varget, Benchmark and H4895. Out of 100 rds only two loads went under a MOA, and that was with starting loads of H4895 and Benchmark.

50 amd 55 gr Vmax hardly shot over a MOA regardless of the load.
