Finally enough solid info to start a real thread. This last weekend I managed to chronograph five commercial loads and one set of hand loads thanks to Adam. The 16" AR is a Palmetto State Armory setup and the 10" AR is a custom build by a buddy of mine.
So - I was surprised at the low standard deviation from the 10" barrel. These were all supersonic loads this time. Next time I will have to test subsonic loads. Sadly we did not have a scope setup on the 10" upper to really test groupings.
