I forgot to mention my OAL
2.15" using 21-23gn 62gn Horn SP
2.25" 27gn 62gn FMJBT Horn SP

These are my Quantified results. You should always use your own judgement. I was impressed with an AR15, 62gn rd moving like a 55gn. MOA groups which is amazing considering it was a PSA stainless, non-lined 16" barrel. I haven't had time to try my A2 results but it's exciting.
