Unfortunately the "paper ballistics" apply the same to both and it assumes BC's are accurate since I believe Litz measured both and the ABLR didn't live up to its stated .625 in a 1:10. But doesn't take into account elevation, ability to judge wind, shot angle, atmosphere, shooter ability, soundness of the chronograph, range finder, each rigs particular capability, scope, yada, yada....but we'll just assume everything is equal.

Have at it..........
