That's a weird result with H4198 in the AR & RARR. Same load in the same barrel length/twist averaged +75fps in the AR?

Did you notice they all were like that? Even stranger because of the results I fired supersonics out of both rifles and it was exactly reverse the RARR had higher velocities.

Nope that is strange. I zeroed in on the H4198 because I've personally had really good luck with it and was primarily interested in seeing those results... Pretty interesting - 5744 was over 100fps faster in the AR.
