Bolt or AR .
people tend to load Bolt a little hotter Vel. than a AR .

I used the following load in my 9in AAC upper

147gr fmj
17grs H110
COAL 2.095
LC 09" x1 processed from 5.56
Rem 7.5 Primer
1822fps(avg)

I didn't delve too deep into accuracy testing bet the load seems well suited for a blaster load. I did x2 five shot strings for a total of ten(10) shots fired through the chrono. High was 1846fps LOW 1814. Pretty consistent.
