Did a search and couldn't find the data...
And...maybe this should be posted in the semi auto handgun section.
All else being equal
Say an AR platform with 10.5" barrel
Would the 5.56/223 around 3000 fps be louder than a 7.62x39 at approx 2200?
Logic tells me that once your above the speed of sound that there would be no significant difference.
