With QL you can create loads that are on an the Optimum Barrel time (OBT). Then chrono the rnds, refine the load (based on MV) to get to the OBT and it might get you better accuracy.Originally Posted by frank1947
I say might because the OBT calculations are time based and do not account for barrel configuration, like a bull barrel vs. a field barrel. We go to heavier/different contoured barrels for a reason and this calculation has no means of including this variable.

Check it out it may work, a lot of the guys at 6mm BR and accurate shooter swear by it.
